Logitech Z680 5.1 Computer Speakers (5-Speaker, Silver) Review

Average Reviews:

(More customer reviews)I have wanted to go digital for long time. My Logitech Z-5300 was an amazing set of speakers, however its lack of digital inputs/outputs isolated its potential to the home PC. Finally, the price of the Logitech Z-680 dropped to an affordable price.
I sold my Z-5300s to another student in my dorm, and purchased the Z-680 from Amazon.com. Amazingly, I received the set within 2 business days via UPS Ground. Needless to say, I am immensely satisfied with Amazon.com.
Thankfully, I had recently purchased a Philips DVP642 player as well, and after reading that the video coaxial RCA cable was the same as the digital audio coaxial, I was all set and ready to go.
So far, I have tested the DVDs Matrix: Revolutions and Lord of the Rings, The Return of the King. I was amazed by the quality of the sound. However, I agreed with the other reviewers that the bass was a bit boomy, especially in Matrix Revolutions. This can be easily remedied by lowering the level of the subwoofer.
When playing my DivX encoded AC3 movies, I saw that changing to Dolby Movie Mode 2 was almost the same as having true Dolby Digital 5.1 surround sound. It did an excellent job of separating the audio tracks among the voice, music, and sound effects.
Edit 9/25/04: Please read my latest update which explains the difference between Dolby Prologic Decoding and Dolby Digital 5.1. Knowledge is Power!
I have yet to hook my Z-680s to my home PC, but there was very little hiss while my set was hooked up to my DVD player. The hiss was certainly not loud enough to warrant annoyance or disturbance.
Update 9/06/04:
I hooked the system up to my PC via coaxial s/pdif. There is no hiss at all. However, when using the analog connections, there was a very noticeable hiss. I could even hear it 3-4 feet away, which became very irritating.
Trust me, if you buy the Z-680s, do yourself a favor and use the coaxial connection. You won't regret it. I have decided to leave the Z-680s as my personal home theatre system as opposed to hooking them up to my PC.
Last note: the Philips DVP642 is the perfect complement to the Logitech Z-680s. You cannot go wrong with them. Having the two items has been a blast.
Update 9/16/04:
Still loving the Z-680s. I have it hooked up to my suitemate's Xbox, TV, and the Philips DVP 642. Since the Xbox and TV both use analog inputs, I used the handy RCA to 1/8 converter included with the Z-680s. I also purchased a 1/8 splitter. I am considering purchasing the Xbox Advanced AV Pack to utilize the optical connection on the Z-680.
Warning: the subwoofer has become ridiculous...after breaking in the speakers for two weeks, normal levels of bass not only shake my whole 5th floor, but the 3rd, 4th, 6th, and 7th floors-no kidding! Surprisingly, the 4th and 6th floors received the most impact--those vibrations go a loooong way! Remember, if you buy this unit, keep the bass at 20%, unless you are watching Star Wars...then pump it up!
Update 9/25/04:
There have been claims that Logitech has been falsely advertising their product as having true Dolby Digital 5.1 when allegedly, they only had Dolby Prologic II decoding.
Now, there is a big difference between the two. The Dolby Prologic decoding technology has been around for a looooong time; I can remember it since 1991 when my family purchased our first home audio set. Dolby Prologic takes stereo channels and converts them into a surround sound environment--to good effect, but nonetheless hardly comparable to true Dolby Digital 5.1, a more recent technology which directs its sound with far greater accuracy to all six channels, frequency, clear separation of effects and dialog, and clarity than Dolby Prologic.
I too, became a concerned consumer after hearing these rumors on forums and consumer reviews on Newegg and here on Amazon. My product box did not dictate clearly whether it had one decoder or the other or both, so I decided to call a Logitech technician. Thankfully, the the Z-680s came equipped with the ability to decode both Dolby Digital 5.1 and Dolby Prologic II.
So when you are playing a DVD you should see "Dolby Digital" appear on the LCD screen of the Digital SoundTouch Control Center. The Dolby Music/Movie Mode that you see when you are playing mp3s or watching a DivX movie is the Dolby Prologic II decoder at work and works very well to its credit.
In a side note, screw Dolby Digital and stick to DTS, the other digital surround sound option the Logitech Z-680 offers, when playing DVDs if the option is available. I have had a greater experience with DTS 5.1 decoding with the Z-680s in the 10 movies I have watched in comparison to Dolby Digital 5.1. DTS makes great use of the surround sound even in movies such as Zoolander [which otherwise makes very little directional use of the rear speakers]. Even my five suitemates agree that DTS has a richer, fuller sound and because of the variety of DVDs we watch during the weekends, it is difficult to say that we are influenced by placebo. There IS a difference :-).
New Setup:
Analog Input - from T.V. & Playstation 2 with stereo splitter
Optical Digital Input - from Xbox
Coaxial Digital Input- from Philips DVP642 DVD Player
Update 10/05/04:
Here is a brief comparison between Dolby Pro-Logic II and Dolby Digital 5.1 using two selected movies:
Dolby Movie Mode with DivX encoded movie Man on Fire:
Voice/Dialogue - mostly center channel with slight residual sound from front left/right speakers.
Music/Score - Evenly divided among front and rear left/right speakers
Sound Effects - Non-directional, evenly distributed. During the gun fight scene when the girl is kidnapped, Pro-Logic II simulates a surround sound effect of gun-fire, making it multi-directional.
Dolby Digital 5.1 for Man on Fire DVD collector's edition:
Voice/Dialogue - Isolated to center channel
Music/Score - Directional music: fades from front to rear speakers or vice versa, varying from scene to scene.
Sound Effects - Directional. Isolated use of rear speakers from rear left to rear right when cars drive by. During the gun scene mentioned above, distinct sounds of bullets "whizzed by" from front right to rear left speakers.
Dolby Movie Mode with DivX encoded movie Star Wars Phantom Menace:
Voice/Dialogue - mostly center channel with slight residual sound from front left/right speakers.
Music/Score - Evenly divided among front and rear left/right speakers
Sound Effects - Non-directional, evenly distributed. Surround sound lightsaber effects can be overpowering as a "large hum" especially with the Z-680's powerful subwoofer.
Dolby Digital 5.1 for Star Wars Phantom Menace DVD:
Voice/Dialogue - Isolated to center channel except in large rooms, echoes can be heard in surround speakers.
Music/Score - Directional music: fades from front to rear speakers and vice versa varying in scenes.
Sound Effects - Directional. Spaceship travel from rear left to front right. Close-up light saber swings begin from rear left and travel to front left, front right, and ends with the rear right speaker.
Update 10-24-05:
OMG! I finally got AC3 to work-but I don't know how! Well, I was playing the Casshern DVD back-up encoded with XVID and AC3. I didn't expect the AC3 to work, so I set the audio effect to Movie Mode. However, I suddenly was hearing discrete audio from my surround sound channels. Bewildered, I went up and listened closely to the center channel, and then the front left channel. Hmmm, either I was having a really good Prologic decode or this was playing in Dolby Digital! I glanced at my control pod and I couldn't believe my eyes--it stated it was decoding in Dolby Digital! Wow! Now I am going to check on all of my AC3 encodes...this is too cool.

Logitech Z Cinéma Advanced Surround Sound System--2.1 Speakers Review

Average Reviews:

(More customer reviews)Logitech Z Cinéma Advanced Surround Sound System--2.1 Speakers
Logitech's Z Cinema Advanced speaker system is an incredibly designed high performance product. I own several Logitech speaker products, as well as others by Creative Creative GigaWorks T20 2.0 Speakers, Altec Lansing Altec Lansing FX5051 5.1 powered speaker system with USB connection, Klipsch Klipsch ProMedia 2.1 THX Certified Computer Speaker System (Black), Harmon Kardon Harmon Kardon SoundStick II 3 Piece Speaker System, and others. I can honestly say, this is a very impressive unit that is well designed for its task. If you have a media center PC setup, this set will make you very happy. Not only is the speaker system ridiculously powerful, the included software is a huge improvement over previous Logitech entries. The included remote rounds out the system and puts virtually all your audio and video applications at your fingertips.
This speaker system will fill a key market niche. The integrated satellite speaker and subwoofer design has more components than meet the eye. Each one-piece satellite speaker has an integrated mid-woofer and tweeter. So these are much more than traditional 2.1 bookshelf speakers. And when you position the speakers as directed and turn on the software surround sound, the sound quality coming out of these approach that of 5.1 systems.
Pros
+ Control your media center PC with a great all-in-one solution and awesome remote
+ Great performing speakers with a ridiculous 35 watts of RMS power per channel, 180 total RMS output
+ Beautiful black and silver speaker and body design
+ Two tweeters and mid-woofers deliver surprisingly crisp sound with or without surround
+ 110 watt subwoofer is simply monstrous and easily fills large rooms with good acoustics
+ Awesome included remote with media center controls and great features
+ Nice integrated support for apps like iTunes, WinAMP, RealPlayer, Yahoo Jukebox, Pandora and Picasa
+ Remote can be configured to work with any multimedia app or to launch a different media player
+ Very sturdy cables and housing are designed to last a long time
+ Power converter integrated into subwoofer so you can connect with a regular power cable
+ Good looking orange back-lit volume and surround indicators on the right speaker
+ Very nice price point for fully integrated media center speaker system and controls
+ USB cable connection is clean and easy - requires on-board port connection
+ Included standard ports for headphones and auxiliary connections (3.5 mm)
+ Simple instructions and plug and play performance for basic use
+ Very modest hardware, hard-drive space and memory requirements for Logitech software
+ True 24 bit digital audio
+ hardware warranty
Cons
- Perhaps overly sleek minimal design could have been improved with physical power and volume controls
- Very heavy system requires extreme caution and should be installed with care and help if needed
- No simple volume controls on the remote, instead included in adjustment wheel
- Would have been ideal to include a few more ports, such as HDMI and S-Video, on the subwoofer
- Satellite speaker cables, while very thick, could have been longer for more configuration options
- No real expandability of the system is apparent; no obvious ports for other satellites or devices
- Many people still demand RF remote capability, this one is only IR
- Those who don't need the remote for Media Center PCs may opt for 5.1 systems at this price
Installation
Installing this guy is simple based upon the included quick start guide. What's cool is that even before the Logitech software is installed, once you make your connections and turn it on it's automatically recognized as a regular speaker system. You don't need Windows Media Center for this to work as a speaker system. This is awesome, and amazingly a lot of the Media Center buttons still work too.
But just note that in order to really take advantage of this guy you will want a Media Center capable PC, with either XP MCE Microsoft Windows XP Media Center Edition 2005 SP2B for System Builders, Vista Premium Windows Vista Home Premium with SP1 or Vista Ultimate Windows Vista Ultimate with SP1 installed.
Installing the Logitech software allows you to have desktop control of the speaker settings, including enabling surround sound. It also allows you to see the options to toggle between the different media applications, including iTunes and WMP among others. You can change settings and really get some control over your MC PC.
Physically installing this guy can be a challenge. First of all, this is a very heavy unit, mainly because of so many integrated components built into the subwoofer body. This is probably a sign of good construction, but handle with care.
The satellite speaker cables are long but could have been longer. The included diagrams give you the impression this was really well thought out for desktop or workstation installs. However, if you have a component center or cabinet for your stuff, you need to be patient and creative to get this set up.
The speaker cables could have definitely been longer to accommodate more setup possibilities. However, in terms of durability and shielding, these are some of the thickest strongest cables I've had come with a speaker system.
The subwoofer body has a silver rimmed front-piece that is not flush with the body housing. It's not a huge deal, but you have to kind of set it up either with the front piece hanging off your component shelf or rested up at an angle. Perhaps this was intentional based upon the lower configuration location noted in the included diagrams.
Sound
The power level output of these speakers is sick, to say the least. Some will be hung up on the "simulated" surround sound feature, a gimmick that has been tried before. Still, even though I was initially unsatisfied, I learned that if you set these up in the right acoustical setting it does perform well. There are two possible setups. For the basic workstation setup where you are literally seated at your media center PC, it works awesome. For those, who like me, want to set this up at an entertainment center, you have to center the system in a somewhat square room with unobstructed walls. Then you can get the surround sound feature to properly bounce in your room.
The total RMS power of 180 watts includes a 110 watts RMS Subwoofer with each satellite speaker producing 35 watts of RMS output via the mid-woofer and tweeter pair. That means your total power output is something like 400 watts, which is really in AV power range.
But the sound is clean. The built in amplifier is well tuned for multimedia sound applications, including gaming. If you have a good on-board sound processor, you should be fine. If you experience any sound effects, definitely take a closer look at your hardware and setup.
Some may feel that you can only get surround sound out of 5.1 Logitech Z-5500 THX-Certified 505-Watt 5.1 Digital Surround Sound Speaker System or 7.1 Onkyo SKS-HT540 7.1 Surround Sound Speaker System systems. Still, I prefer 2.1 system with high quality components over 5.1 systems with small and disappointing satellites. There's a lot of nice 5.1 systems out there, don't get me wrong. I own several. Still, this system sounds better than a lot of those. Definitely have to test drive it to hear the difference.
Features
The power adapter is nicely integrated into the subwoofer, so you power up via a standard plug, no power bricks so many people hate. The speakers have right and left noted on the bottom. The right speaker comes to life when you turn it on with the remote. It has a nice orange read out that shows when it's on, the volume level and surround sound setting. The right speaker also includes jacks for headphones and auxiliary connections.
I really wished they would have also added physical volume and power control buttons and knobs. That way, when I want to hook up one of my MP3 players, I wouldn't need the remote to turn it on.
The Logitech software is actually vastly improved for them. I've not always liked some of the integrated software in the past, but this one was a huge improvement. The only minor negative I can give it is that it is automatically included in the startup folder even if you install the software with the option of not turning on at startup. So you have to manually remove it from your startup if you don't want it on all the time, a minor inconvenience.
The remote is the nicest part of this set functionally. For those with Universal remotes, you may wonder why you need this. This remote allows you to access your multimedia apps seamlessly. You can set up 4 presets, though it's less than intuitive.
You've also got some basic navigational buttons that allow you to go back to your previous app. There are included buttons for shuffle and repeat plays, and...Read more›

Antec Soundscience Rockus 2.1 Review

Average Reviews:

(More customer reviews)I recently bought a 27in iMAC and was not satisfied with the speakers that came with the monitor. I intend to use my desktop monitor to watch movies in my bedroom and wanted a more powerful sound system. I was looking for something within the 150-200 range and was deciding between the Bose Companion 3, Harmon Kardon Soundsticks, and the soundscience Rockus. Bose is obviously a known brand, however, it's a bit expensive and I really didn't want to spend that much on speakers. The Harmon Kardon sounsticks are beautiful but these speakers have been on the market for quite some time and I wanted a newer technology. What initially drew me to the Rockus is the chrome finish on the speakers which looks great in my room. After reading about the 3D sound technology, I couldn't wait to test these speakers out. And it does not disappoint, the sound is crisp and despite what some reviews may say, I thought the bass was pretty powerful. I turned them up and walked out of my building and still heard the thumping from the bass. Loved the 3Dsst technology, it really brings action movies to live and enhances the movie watching experience. I've also connected these speakers to the tv in my living and it sounded great as well. You can also easily hook this up to your ipod, iphone, ipad, and other mp3 players. I switched it to music mode and it sounded 100 times better than my speakers on the iMAC.
Overall, the speakers look and sound superb! You cant really go wrong with these, I recommend this to anyone.

Acoustech H-100 Cinema Series 500-Watt Front-Firing Subwoofer, High-Gloss Black Review

Average Reviews:

(More customer reviews)I was very hesitant to buy this speaker but I had just lost my old one and money was very tight, so I did'nt have much of a choice. I researched it at Bic's web page and every audio page that I could come up with. I did'nt read one negitive thing about it. The only thing I could say that may turn someone away, would be that this is a sub for a normal,(small to medium) size room.
The encloser, grill and speaker all look very high quality, very nice fit and finish.
The sound that comes out is quite good, of course your placment will change the sound to your own tastes.
I have it set up to about one half volume and to the parameters of my receiver, it fills my room with full rich bass and responds beautifully to movies, I turn it down for music because I don't really like my music with bass as the focus.

Listeners who want to treat themselves to the best in home theater sound need look no further than the Acoustech H-100 front-firing subwoofer, which reproduces powerful, room-filling bass. Featuring 150 watts of continuous power output (500 watts peak) and a 12-inch, front-firing, long-throw woofer, the H-100 makes movies sound explosive and gives music a deep, full-bodied appeal--all without causing unwanted boominess or distortion. The subwoofer delivers a wide frequency response of 24 to 200 Hz, along with a max acoustic output of 115 dB SPL (sound pressure level). It performs particularly well when teamed with Acoustech's other home theater speakers, which are customized to match the subwoofer's output.
A further bonus stems from the sub's striking rear-vented cabinet, which is outfitted with a high-gloss black finish (think piano surface) on the top and bottom. The finish adds extra flair to the sub's design, as does the copper color of the woofer (revealed when you remove the grille).
The H-100 measures 15 by 17 by 18.25 inches (W x H x D) and weighs approximately 42 pounds. It's also covered by a two-year warranty on parts and labor.

Yamaha YST-SW315 10-Inch Digital Pro Series Subwoofer (Black) Review

Average Reviews:

(More customer reviews)I picked up the Sony 8" (SA-WM250 100-Watt) Active Subwoofer recently, and it's quite nice (especially the price at under $100.00). But this smaller system can't hold a candle to the Yahama. This 10" system pumps out clean, crisp base and its cut-off option allows the user to limit the higher frequency response of the sub-woofer (and let your mid-range speakers do the job). The result - a pretty massive, well defined bottom that can be as subtle or as "in your face" as you like it and which will nicely compliment just about any existing audio/visual system.
Because I use a pair of smaller AAD speakers, I keep the volume level for the subwoofer at below 50%, but the frequency cut-off a bit higher (110 hz out of max 140hz) for a nicely balanced, very full sound. Another nice feature is a bass button selection for either (i) music, or (ii) movies. The latter provides maximum bass response - suitable for achieving something similar to what you get in movie theatres - the rumbling bass that lodges in your stomach. The former, music option, is ideal and very complimentary to my existing stereo arrangement.
If you're unhappy with the response of your shelf speakers (want more oomph?), you'll love this Yamaha subwoofer. It'll add depth to your existing system, and add real luster to your audio-video setup. I recently re-watched "The Two Towers" on DVD using the Yahama - the experience was truly like a return to the theatre.

Yamaha's YST-SW315 offers 250 high-efficiency watts--enough power to deliver shattering, movie-theater-like bass effects. Full enjoyment of Dolby Digital and DTS surround sources requires deep, clear bass. This is especially true with 5.1- and 6.1-channel sound, because the ".1" channel is dedicated to the bass frequencies. That means you not only need a subwoofer, but a high-power subwoofer capable of handling extremely low frequencies. The YST-SW315's down-firing 10-inch driver translates power into clean bass sound, and the YST-SW315 boasts a frequency response of 20 to 160 Hz (-10 dB at the extremes of the range).The YST-SW315 delivers high power at deep bass frequencies, with excellent stability and low power consumption. This is made possible by the sub's highly efficient PWM (pulse-wave modulation) digital-drive power amplifier. The amplifier achieves superior conversion efficiency by minimizing power loss from the power transistors. It delivers stable audio power while minimizing AC power consumption and heat production. As it requires no output filter coil, it's extremely quiet with low distortion.Yamaha's patented Advanced Active Servo Technology (Advanced YST) generates incredible bass from small speaker enclosures. This system uses negative-impedance feedback in the amp and a Helmholtz resonator in the speaker to provide strong and accurate bass.QD-Bass (Quatre Dispersion Bass) technology uses a down-firing driver with square, pyramid-shaped reflective plates to radiate sound efficiently in four horizontal directions. The reflective plates (not used in other brands' down-firing subwoofers) negate any effects caused by the floor surface and reduce resonance between sound waves reflected from the floor and the unit. Most other systems use circular cones, but the YST-SW315 avoids firing sound into the legs of the cabinet by radiating in four directions. Changing the height of the pyramid varies the acoustic load, permitting relatively simple high-cut adjustment and improving bandpass properties. QD-Bass also grants greater freedom of placement, since the sound radiates with equal effectiveness in all directions.The user-adjustable, continuously variable high-cut filter sets the highest frequency the subwoofer will deliver. It can be set anywhere from 40 to 140 Hz. For instance, if the filter is set at 75 Hz, only frequencies 75 Hz or below will be delivered by the subwoofer. This allows the sub's output to be matched to the lowest reproducible frequency of other speakers in the system and the room's acoustics for a seamless presentation.The rotary volume control permits the perfect matching of the sub's output to the overall volume of the system. The YST-SW315 has a signal-sensing circuit. When the subwoofer detects an audio signal, it turns its power on. When it senses no signal for several minutes, it shuts itself off.Yamaha's BASS (Bass Action Selector Switch) tailors the sub's output for video or music at the touch of a switch. Two sets of inputs let the sub accept either line- or speaker-level inputs, while a handy phase normal/reverse switch makes it easy to phase the subwoofer with the other speakers in your system.Three-way speaker terminals accept banana plug and a variety of other connectors, as well as speaker wire, and the YST-SW315's thick, rigid MDF cabinet reduces vibrations and resonance. The speaker's handsome black-ash finish blends in with room decor and complements many furnishing styles, and it's magnetically shielded so you can place it near a TV or computer monitor without degrading the picture.What's in the Box Subwoofer, user's manual, and warranty information.

Clark Synthesis TST429 Platinum Transducer Review

Average Reviews:

(More customer reviews)This is one of those products that you are either crazy about or just couldn't care less about. I recommend this product for Any kind of audio or A/V application. With the correct amp this product adds a dimension to the enjoyment of music you don't even know is missing until you turn it off.
No denying it is expensive especially when you consider you still have to buy an amplifier. However, I have tried other tactile transducers, notably the Buttkick LFE, that cost much less, and there really is no comparison. Please note, this is a review of the Clark Synthesis Platinum, their most powerful tactile transducer. The effect produced by the Clark Platinum unit is immense. It's akin to pulling the switch on a low RPM power drill only to find that you have more torque than you need, Lots more! The Buttkicker unit never approached the output of the Clark Platinum and under the same levels of amplification tended to bottom out. Furthermore, I have had 4 Clark Platinum units in use for over 3 years now, (one of them over 5 years), without a single problem. The Buttkicker eventually gave up the ghost; after two years of use there was finally no dicernable output from the unit, at amplification levels that had the Clark Platinum units practically bouncing the couch off the floor, (which I suppose should happen if a T-Rex walked into your multi-media room/theater). In defense of the Buttkicker company, they make what might be the best tactile tranducer amplifier around. The amp is comparitively inexpensive, has Lots of power, and the added versatility of user controllable frequency response filters. I have two Buttkicker amps powering two Clark Platinums (wired in parallel) each with the gain control set at a notch below half power. This gives the amp plenty of head room for those particullary troublesome passages.
I suggest you try it. If you don't like the effect, try it at differnt levels. If you still don't like the effect, well...you won't have any trouble getting rid of it somewhere but I can pretty much guarantee that someone in the family is going to like it so mount it into the frame of their favorite chair, (see Clark Synthesis website for mounting suggestions). They'll thank you.

Velodyne DEQ-15R 15-Inch Powered Subwoofer (Black) Review

Average Reviews:

(More customer reviews)This is the third sub I've owned, but the first Velodyne. It was purchased to enhance a new speaker system for the surround-sound in the living room...which is 18' X 16' with 18' ceilings. It's a big, open room that opens to a kitchen on the side. The previous speakers were DefTec 7002's with the build-in subs, and it never sounded right in the living room -- horrible bass, poor dialoge, etc. Not the case here at all. The sub setup was super easy. Immediately the entire system sounded better than the others I've had, and provided focus, "thump", and low-end effects that I've missed in other movies. I popped in the new Star Trek on Blu-Ray and, pardon the pun, was immediately transported into the movie and off the sofa because of the better sound-intro, explosions, and the like. My wife noticed it as well and remarked that it was like "seeing a movie for the first time".
Music was equally good, and since the sub has separate settings for listening types (as well as 90 degree phase adjustments) it was really easy to get fantastic low-end sound on different songs and music types --- she likes country, me not so much. Rock, some jazz. It all sounded great. Authoritative. Like it was easy to go low and not muddy the sound. Since a sub that big can punch you in the chest if you let it we found ourselves turning the volume down a bit and adjusting the crossover so it didn't become too much. Great buy for the money. Great sub.
Highly recommended.

Big bass doesn't have to mean big hassle if you choose the DEQ15R 750W powered subwoofer. It's the ideal combination of technology and an intuitive interface. It includes a remote control with front-panel feedback, and one-touch Auto-EQ bass correction with an included microphone. It's great bass, made easy.

Klipsch Synergy KSW12 12-inch 105-watt Powered Subwoofer Review

Average Reviews:

(More customer reviews)Having heard this sub while back, I have to agree with the first reviewer. It's acceptable for HT use, but poor for music; regardless of their nonsense about dynamic power.
Although, movies may get away with "large, short-term peaks of power", many music will demand nearly constant, power. In virtually all movies, special effects and sound tracks last only a few seconds; all most all of it is a dialog between the actors. Certainly, there is no bass in dialogs. Music is different. I mean, how often do you hear a couple note of bass, followed by few more notes several minutes later?
I'm not sure where some of the reviewers get their information, but there is no such thing as a "crisp & sharp" bass. Crisp & sharp implies, fast rise time, which means there are significant higher harmonic(high frequency) contents in the sound. Anyone who understand the concept of harmonics and Fourier series should understand this. The "crisp & sharp" part of the "bass" comes from the satellites. The most common reason why some bass sounds muddy/boomy is because of poor integration between the satellites and the sub or due to the standing waves caused by the sub-room interaction.
I also don't get how anyone can get "imaging" from a mono sub. Even if you use two subs, low frequency sounds are difficult to localize. This is the very reason why you can place the subs significant distance from the satellites.
The rattling of the object in the room has EVERYTHING to do with the bass, regardless of the distortion. Obviously, the reviewer has never experienced the room pressurized by two 15" subs driven by 1000+ watt pro-audio amplifier. You can barely hear it, but you will definitely feel it. If you have never heard/felt a real sub, then you really don't have a good reference point to judge the other subs. All you can do is note the significant improvement KSW-12 made over the original 8-inch "sub".
That being said, the KSW-12's low end of the frequency response is bit lacking for an "almost-high end sub". It seemed to struggle with the loud rap, as well as the classical music. For movies, it wasn't as bad. It handled most action scenes well, but combat scenes with exaggerated explosions, the sub clearly ran out of gas.
Objectively, the specs are some what misleading. Why would anyone spec the subs at 1/8-space? I've seen half and 1/4-space specs, but 1/8-space? Also, how dynamic is the "dynamic power"? This sounds too much like my plastic 2" 100 watt(PMPO) multimedia speakers I had back in college.
In short, KSW-12 has respectable volume, but is unsuitable for continuous music with significant bass content. It also doesn't have the low end impact. It's spec are completely unrealistic and you won't get anything near the listed spec in a typical living/family room playing music, or movies with heavy action sequences. In the end, it's only a bit better than a typical consumer level 12" sub.

REVIEW: Complete a powerful home theater system with the deep, driving bass of the Klipsch KSW-12 powered subwoofer--perfect for combing with high-performance Klipsch Synergy Series surround sound configurations. It couples a 12-inch driver to the floor for optimal performance. This subwoofer's high-output, down-firing design "grips" the air and fills a room with low frequency energy that's heard and felt with undetectable distortion. The built-in discrete MOSFET amplifier and 12-inch fiber-composite woofer are as efficient as they are reliable. It provides 105 watts of FTC-rated continuous power, and it has a dynamic power rating of 440 watts. (Dynamic power indicates the actual power this amplifier will deliver to the woofer under normal operating conditions.)
The woofer is composed of a Santoprene rubber surround with a fiber composite cone which enables Klipsch subwoofers to deliver on their promise of extended bass response and maximum reliability. This subwoofer accepts LFE, line-level, and speaker level inputs, making it easy to add to the Quintet Microsystem, the Synergy System 6, or any other Klipsch inspired arrangement. The KSW-12's jet ash veneer vinyl finish creates a deceivingly subtle exterior for its earthshaking sound capabilities.

Logitech THX-Certified Speaker System Z623 Review

Average Reviews:

(More customer reviews)I love listening to music and watching movies on my computer, but I have always relied on relatively cheap speakers (or even my built-in laptop speakers) to provide my sound. I decided to order these speakers and take my music and videos to "the next level" and see if these speakers could deliver the loud, clear, and rich sound I expect from more expensive stereo systems and speakers.
Below are my positive and negative evaluations of the Logitech Z623 speaker system.
Positive:
- The subwoofer is huge, and provides a nice, rich, bass sound. I am amazed at the loudness and clarity of the bass.
- The speakers may seem little, but they produce a big and rich sound, with very little vibration or feedback.
- The overall sound quality and clarity is impressive. When I listened to my favorite songs, I heard sounds and instruments I had never heard before. Watching videos with these speakers has opened up an entirely new (and great) listening experience!
- To test the unit's power, I turned the volume on full blast (with the computer volume turned on full as well) and the sound was pretty much flawless. I didn't hear any rattling or feedback. These speakers are pretty loud, and definitely loud enough for what I need.
Negative:
- The cords are a little short, but not too short as to be annoying.
- The unit is large (the entire set weighs about 22 lbs). This means that moving the speakers and subwoofer is a little inconvenient. I am used to moving speakers around with my laptop. I really can't do this with these speakers.
Overall, this is a great speaker system, and I am glad I upgraded from the cheap speakers. Until now, I didn't know what I was missing using cheaper speakers. I plan on using these speakers any time I watch a video, listen to music, or play games. Their loud and rich sound has turned my computer into a powerful stereo system (I want to throw a party just to show them off!). If you want to take your listening to the next level, these speakers are for you.

Sony SSF-7000 Floor-Standing 4-way Speaker with 8" Woofer (Pair) Review

Average Reviews:

(More customer reviews)Purchased and Received these speakers just a couple days ago. The free shipping was great considering the weight of the speakers.
They are great! No complaints here. I was upgrading from my original aiwa speakers (made by sony) in my home entertainment system. The difference is amazing. Highs mids and lows are all great. I always recommend a powered sub woofer, I do have one. However, if you get these speakers you can get by without one.
My listening interests are varied. I have listened to Kiss, ELO, The Hollies, Peter Frampton, Supertramp and some classical on these speakers so far. I have also viewed a couple movies using them. All sounded great. "Do You, (Feel Like I Do) sounded GREAT! All the ELO was crisp, clean and clear. The only "booming," as mentioned in the other review, that I heard was while listening to "Long Cool Woman In A Black Dress" by the Hollies. However, it did appear to be a bass sound that was appropriate with the song, not anything abnormal. But then again, it may just be different taste.
Oh, and the picture shows the speaker as looking more of a grey than black. They are black, not the grey like the picture shows. that is good since my tv and all my entertaiment system units are all black.
My advice is you cannot go wrong with these. If anything changes I will update.

ButtKicker BK-LFEKit Low Frequency Effect Kit with Amplifier for Home Theater Review

Average Reviews:

(More customer reviews)The Buttkicker is a "tactile transducer", meaning it turns sound into shaking. It's just one of four players in that niche; the others are Clark Synthesis, Aura Bass Shaker and Crowson. But the Buttkicker is the best; the Clarks are less intense and less concentrated in the low frequencies, the Auras are $20 units with all that entails (such as lack of shake and lack of finess) and the Crowsons are purely under-couch devices.
The Buttkicker adds a bit of shake to your home theatre. It doesn't replace the subwoofer, but sort-of turns the floor into a lower subwoofer. And I love it. But there are some things you should know.
It needs a LOT of power, so this LFE Kit (with Amp) is probably the best choice to start with because you can't drive it from your receiver.
Second, one LFE Kit will do a sofa nicely, but if you, like me, mount it under your floor, you're gonna need two. Possibly more, but probably two. Because that's a LOT more mass to shake, and otherwise they'll be maxxing out and making a loud knocking noise. (You can drive up to four Buttkickers with a single Buttkicker Amp.)
Third, it's not like riding a rollercoaster. You'll feel the floor shake from loud sound effects, bombs, etc., but don't expect magic. It makes the movie more real, but it doesn't toss you around.
All that said, it's a great addition. If you can afford the cost-of-entry, you'll be amazed how shallow the system feels with it off.

Ideal for movies, music, and gaming, the ButtKicker LFE "silent subwoofer" lets users experience realistic special effects and concert-quality music without waking the kids or disturbing the neighbors. Rather than emitting loud rumbling sounds during each explosion or heavy bass passage, the ButtKicker simulates the "feeling" of the effect through your couch, chairs, and other furnishings, letting you sense the low without the excessive volume. The device accurately mimics the sensation of many natural and manmade sounds, such as earthquakes, thunderstorms, rocket launches, waves, explosions, tornadoes, volcanoes, dinosaurs, sound effects, and all styles of music.
The Buttkicker installs easily, including under chair or couch mounting to create a tactile experience.

ButtKicker BKA300 Wireless Home Theater Kit with ButtKicker Advance and Power Amplifier Review

Average Reviews:

(More customer reviews)I purchased the ButtKicker BKA300 based on prior reviews here. This is my first time owning one of these systems. The intended purpose of was for more immersive movie-watching and playing on a PS3. The kit was setup with a HDTV using the line out on the TV using a Y-adapter to split between it and a 2.1 (two satellites one sub) speaker set. The rumble unit was setup under one of the four rear legs of a three-person sofa.
Watching live concert music on the Palladia channel really gives the feeling of being there. I started noticing that on regular TV programming one can hear muffled sound on most dialog as if the sofa was the speaker. This is a bit distracting, and an annoyance that could be addressed by sound proofing the furniture a bit.
The blu-ray version of The Dark Knight has some loud low frequency passages that causes a loud metallic thump. At first I though it was bouncing against the furniture or floor, so I took a couple of mouse pads as a quick fix test and put them in between the floor and another between the rumble platform and the sofa, but it did not fix the problem. I then watched Pirates of the Caribbean, again on blu-ray, fortunately not much of an issue here.
Gaming on the PS3 was another issue. Playing Call of Duty 4 with the rumble kit really brings gaming to a whole new level. Unfortunately, once I went online, grabbed a sniper rifle and aimed at someone, every heart beat the game produces started causing the metallic thump. I had someone else play while I tried troubleshooting the problem and noticed it was coming from inside the rumble module as if it was bottoming out. A few days later a family member was playing Resistance 2 and the module was not working. It had stopped working within an hour of playing, and was very hot to the touch. Once it cooled it worked again so it appears that it disables to prevent damage. I tried multiple settings for several days, lowering the "volume" on the amplifier, selecting different modes (music,movie,game,) but was not able to fix the problem.
Ultimately, I decided to return the unit. Really disappointing, I recently learned from reviews of the bigger brother (400 watts min, 1100 watts max) unit also bottoms out; this one is 50 watts. I may still give it a cautious try.
