    The sony subwoofer has a decent size, and it's just alright for a home usage. I like the power saver of the subwoofer because it automatically turns itself on/off.

      Hello SONDRA,

      Fantastic! We are extremely pleased to hear you are satisfied with the outstanding sound quality of our SA-CS9 115W 10” Active Subwoofer. To turn up the bass sound/volume, you will need to turn the LEVEL clockwise of the subwoofer. You may also find different sources will perform better than others due to different types of audio compression and transmission. We greatly appreciate your feedback.

      Hi BEAR, 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
