      Hi Hydrox2000, 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

    This thing has the potential to scare your neighbors that there’s a bomb going off in your house. If this isn’t enough of an endorsement, I don’t know what it. It’s what every sun should be.
