    I replaced an older and larger Sony subwoofer with this model and was a little worried it would not live up to the older model. I was wrong. I placed this in the corner of my home theater and it will rock the house if you want that. Very nice.

    For the price this subwoofer can't be beat. On-line reviews confirm what I have experienced. If you need a subwoofer, or as I did, need to replace one..this one cant be beat.

      Hi JohnA, 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

    We have a smallish open concept living room kitchen combo. This sub works great for us. Movies and music are enjoyable with the extra bass kick. Get on sale and be happy. The auto off function isn’t great when watching movies or tv. Shuts off too frequently. Easy to just keep it on.

    This subwoofer is unbelievable!! It is a bit bigger than I wanted but the power is crazy, The whole neighborhood could hear and feel it and it was shaking the whole end of the house from the room I put it in. Good thing there Is no "noise ordinance" where I live.

    I was going to buy two of these based on all of the positive reviews but opted to start with only one just in case. Turns out, one was really all I needed to achieve a theater experience. It would be difficult to find a sub as good as this one for the price.

    I have had several subs in the last few months but this is the best. Has pretty deep bass and it's not boomy. The best thing is it works good with movies and music. Let it break in for a few days and you will hear a big improvement.
