    This speaker is small enough to fit just about anywhere, but still does a good job of adding some bass to the surround system.

    This is a great subwoofer! I ended up taking it back because it was so loud that it was too much for my cheap surround system. If you like to feel bass in your chest this is a sub for you.

    I like this as it hits with heavy bass and it's loud, the only thing so far it gets a little muddy at times, likely because I need to tweak it. 100% worth the money.

    I used to have a wireless Polk Audio sub that came with my soundbar. Once I got a new soundbar I needed a sub to pair with it. This powered sub is much better then the polk wireless one. It delivers excellent low end and if you wanted you can crank it up to really get the bass feel in your chest. Great compliment to any system and a good price.

    I bought this sub to add to an existing 5.1.2 system. It is fairly effective, but in the beginning sometimes it would shut off by itself even when the other sub was still on. I thought I had a faulty sub but after fiddling with the RCA cable I found that I hadn't plugged it fully into my receiver. After fixing that I haven't had any problems with this subwoofer. It sounds like what you would expect a subwoofer to sound and the auto shutoff feature is nice for saving on power.

      Hi Zustand, we're glad you like your subwoofer. SA-CS9 gives you deep, rich bass from this powerful active subwoofer, and it includes a built-in amplifier with up to 115 W power output. The unit is powerful and compact, perfect for easy installation in tight spots. Because of the reduced baffle area, the speaker minimizes sound field distortion for optimum clarity and precision. Thank you for choosing SONY. ~Earl Sony_US

    Works great for a small to medium space. It is ported, so keep in mind it’ll be boomier and less tight of a bass, which makes it better for movies than music. Recommended when on sale.

    Nice sound at a great price. It has way more bass than I’ll ever need, so much so that it can completely take over the low end. I use it for music and have to adjust it way back, but I would imagine for home theater it would be crazy.

    This sub gets poor reviews in audiophile circles, but as a casual enjoyer I think it's great. Set LPF dial to 80Hz and boosted 3.0dB on my receiver. It goes on sale regularly for $150, at full price it's a harder sell.

    This is the kind of quality I expect from Sony. For $200, this sub has really nice bottoms and great punch. Easily sounds as good as my Polk sub that cost twice as much. Just be sure to set the crossover knob to a lower feequency for the best sound. At a higher setting it does get muddy sounding.
