      Hi MoviesatHome, we're glad you are enjoying 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 is a good value budget subwoofer. It sounds good for what you pay but dont expect it to shake the walls and shatter windows. Im currently using this sub connected to some powered bookshelves for my computer. No complaints so far and it works great for the purpose intended.
