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.

Reviews: "The Klipsch Reference ensemble is pretty impressive for the money. It's a smoothly blended system for music, and the horns effortlessly put you in the middle of a film's dialogue and special effects..."

While the FTC power rating indicates power available on a continuous, long-term basis, subwoofers do not rely on that type of power. Instead, the amplifier is called upon to deliver large, short-term peaks of power to be able to support the wide dynamics required by today's digital music and movie formats. In addition to the required FTC power rating, we've provided the dynamic power rating as a better indication of the product's true performance.

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. 6 of 6 people found the following review helpful. Great Sound for Home Theater By Online Shopping Guru I see some of the ratings talking about the music sound quality compared to less expensive units. First of all, read the title of the item. It says Home Theater. I love the thundering response on this unit when I'm watching movies. Second, once you get the settings right on the subwoofer and your amplifier, the sound it great for music too. 4 of 4 people found the following review helpful. Superior subwoofer for the money By James Lafond Replaced an old Onkyo sub with the Klipsch KSW-12 to mach the rest of the Klipsch speakers i have. A night and day difference compared to the Onkyo,i mostly use it for watching movies and it has more than enough power,shakes the couch from 15 feet away with more power to spare. Awesome sub,A++++++ See all 16 customer reviews...
