    Creates some awesome lows for my home theater setup. I like that you can adjust the output on the speaker itself. The auto shutoff is helpful to save on electricity.

      Hi KingFang, 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. Thank you for choosing SONY. ~Earl Sony_US

    I was not expecting this sub to fill the room with as much sound as it pumps out. Not to mention when correctly equalized the low frequencies dont distort nearly as much compared to other starter subs.

    I use this sub in my living room. I like the adjustments on the unit for bass response. Only drawback is it take a little bit to kick in, but overall no big deal. Really fills out the room that was missing with my older non-active sub. Sounds great!

    I needed to buy my father a new subwoofer as the old one went bad. Can't go wrong with Sony. A bit on the larger side, but what pumps out is exactly what we were looking for.
