      Hi KingFang, 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 is my second Sony sub-woofer so I assumed this one would be of similar quality, and it was. I admit that the price was a main factor since it was on sale at 50% off but, this is well worth the full retail price.

    Couldn't beat it for the price. I don't like to be overpowered, and this subwoofer suits my needs very well. It fills in the low frequencies I new I wasn't getting from my Polk towers.

    I bought this to replace a 15 year old sub that finally blew up. I use it in my basement on my home theater system and love the punch it has watching movies, TV and games or just crankin up the music, it all sounds so much better, and deeper! Great buy!

    Creates some awesome lows for my home theater setup. I like that you can adjust the output on the speaker itself. The auto shutoff is helpful to save on electricity.
