    Love these speakers. They really fill my home theater with clear deep realistic low range sounds. I especially like to view action/war movies where these really perform. Great buy.

    It has a ported 10” subwoofer in a relatively small enclosure. There is plenty of power for LFE in a surround sound system in an apartment. It was on sale and I used Best Buy points to make it an exceptional value.

    Love it. It has a great sound and features that are easy to control. I'm not a lover of a droning sub bass, which you can eliminate, and still have a truer bass sound that pops.

    Great and clean bass that rattles your walls! Paired this with a Sony AVR and instantly fell in love. If you're going Sony core, know that this bass plays really well, especially for its price.

    Easy to connect to my Onkyo receiver with a single RCA cable. Sufficiently bassy for the action movies I watch on a regular basis.

    Great low end sound and options. The sub cuts on and off (on auto setting) to save power. Other then the clicks you would enjoy this feature as it allows you to slow down power usage but when bass hit, it kicks all the way in.

      Hi Honest, we're glad you like the sound quality of our product. 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.

    I have several other more expensive subs. So, my bar is set high and this Sony 10" stacks up. The auto on feature (when signal is detected) works well and the punchy/responsive bass is a perfect compliment to the overall system.

    I had an old system that the subwoofer got blown. I ended purchasing this Sony subwoofer and I could not be happier. Make sure your system accepts active subwoofer and not only passive one.

    I purchased this subwoofer during black Friday sale because I considered the price a steal. I must admit that the bass this subwoofer is much better than what I expected for the price. I am very happy with this product. The only reason I don't give a 5 star rating is because of it's low power handling.
