    Works seamlessly with my receiver and current set up, right out of the box it is a solid unit, and really brings the movie/video game/music that you’re playing to life.

    These Subs are perfect for my house and for the price point. I am not audiophile status meaning $50,000 and up home theater setup, so I would not recommend these for that person, but for the rest of us they are not only good but they have lasted years. I have a lot of sony products because my other brands didn't last more than a year to a year and a half.

    I was looking to replace our sub at church mainly because of an offensive noise it made when no signal went to it for five minutes and it was shutting down. This one was simply unplug the old on and plug in the new one and it didnt cost too much either. Sounds great .

    Received this subwoofer as a Christmas present. Our old sub had gone out on us a while ago and we had adjusted to the audio without it. Since hooking up to the amplifier the audio is leaps and bounds better. We had forgotten what it sounded like to have bass with a movie. Overall this was a great purchase on my parents part and my wife and I are very happy to this point.

    KLIPSCH subwoofers are a very necessary element to Your KLIPSCH speaker network they all know each other and are designed to FLOW together flawlessly! You’ll need the Low’s when You reproduce music as in Symphonic music, Jazz, Rock or Soul; don’t forget that movie sound reproduction is essential in modern culture and when the sound drops (Deep Lows) in a movie so will Your audience!

    I bought 2 subs for a living room home theater (12 x 17') but found them a bit lacking for movies or music.I then moved one into a smaller room (11x12') and these sounded just fine.Using this with an Emotiva Ta-100 and 2 Bi+ speakers or with 2 Sony SS-CS5.Also suggest placing on a 1/2" wood platform if on a carpet.
