Pleasently Surprising Oomph
Great sub! Connected this baby to my other Klipsch speakers via the sub out port and it worked instantly. (I did have to buy a separate insulated sub wire as this product does not come with one) I was able to get this on sale for 50% off and for that price it's amazing! The subwoofer is larger than expected, but I'm considering that a good thing in the end. (No need to upgrade in the future for me) The adjustable sound allows for subtle bass or wall shaking bass. All and all, this was more than I could have expected for the price!

Lightweight, good performance, rumbles the lows but with control
I don't have the world's best back so the light weight of this subwoofer relative to its size and performance was appealing. It has good extension and can reproduce quite low frequencies, though its EQ has a hump at about 55hz. You can EQ that out or just enjoy it, nobody is going to make you stop! Group delay is good for its size and rear-ported construction as well, better even than some vaunted performers in its on sale price range. Ample dynamic range for cinematic low frequencies and when dialed in, it has a lively and relatively quick low frequency reinforcement for music as well. I pair mine with Klipsch RP-600m (first gen, love them) and set the crossover to reinforce from about 60hz down. Its loudness has been more than enough for my space, it can overwhelm the living room it is in when movies rumble! Feel it moving that low low air into the kitchen and other rooms even. But, to be maximally fair, if you are in a very large room you might want to consider a larger diameter speaker model or perhaps a higher output unit. I've had zero complaints about it's output but it is somewhat conservative compared to the Reference Premiere subs and some competitors, and it has rock solid DSP limiting that stops it from exceeding its capabilities. In my personal use even with bass impact action films I have not met its limits!

Excellent subwoofer a definite upgrade from my original sub. Earthshaking bass round and smooth no distortion no baffling. Great buy

Very happy with it
Massive upgrade from my previous 12” powered sub. Looks great and feels very solidly built. The sound is great. For the price I could not ask for more. Has far more than enough power for demanding movie soundtracks and music. Might buy a second one to use one on each side as speaker stands for my floor speakers.

Klipsch has the reputation of being phenomenal - because they are.
Amazing - Did not realize how poorly my other Onkyo sub was responding, especially to deep bass when watching an action movie. It used to rattle and pop during those scenes - this Klipsch handles it like a champ. So much clearer and forceful. It also sounds great with music - although most of what I listen to doesn't have a deep, driving bass. Would definitely buy it again should the need arise.

Awesome
Subwoofer produces loud, deep, undistorted bass. Couldn't be happier with the sound, just two small complaints. It is quite large but also has a nice aesthetic to combat this so not much to complain about here. Second is that mine did not come with a rca cable. Luckily I had one to my existing 10" woofer, but still. Couldn't hurt Klipsch bottom line that much to throw in a basic rca connection cable.

Estou usando esse subwoofer em uma sala de 40m2. Ele tem a presença do subgrave muito nítida e forte. Mesmo em volumes baixos. Toca muito bem, subwoofer de impacto, muito top mesmo.
