    As soon as I heard the Base sound coming from this Sub Woofer I was Estatic. When I hear the base sound in a movie theater, I wish to duplicate the same sound at my house. This Sub Woofer comes Very Close.

    This will rattle your teeth if you have the volume cranked all of the way up. I use this in a 5.1 setup to watch/stream TV and movies and it does a pretty good job for my little basement setup.

      Hi Sajkal, we're glad you like 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

    This subwoofer does sound good and works well; however, the 'auto' power feature isn't great. It's supposed to turn off the unit when it's not being used, but the unit turns off too often which is annoying because there is an audible click when the relay switches it off.
