    Great subwoofer for the price, wouldn’t get it if was anticipating it could bring the boom to a large area, but for smaller areas, it does have tight and smooth bass, not overkill and sounds wonderful at moderate to moderate/high volumes.

    I have this unit behind my couch in a dual sub woofer setup. I didn't believe it would add much to my movie experience being under $200. However I was proven wrong. On a very low setting this unit vibrates my chest and couch. Perfect for Action movies.

    I initially purchased one subwoofer but loved the sound that I purchased another one a week later. Both are in my media room and the kids are going crazy over the sound. It gives you the theatre effect and the rooms feel like it vibrating with the base. Highly recommend!

      Hi Kman37, we're glad you love our product. The 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

    My father has a Vizio soundbar, and it does great for increasing voice volume, but it was definitely lacking when he listened to his music. Luckily there was a subwoofer port so we bought him this Sony sub and it does an amazing job of adding bass to everything he watches and listens to
