    It's a decent subwoofer to add bass for a sound system but highly recommend saving your money and going with a PB-1000 instead. Blows this out of the water and the only subwoofer I would recommend under 500.

      Hi Munchkin,

      Thank you for your review.

      We are so sorry if our SA-CS9 115W 10” Active Subwoofer did not live up to your expectations, and that you recommend a different subwoofer brand.

      Depending on the audio source, the bass sound of our SA-CS9 may not be so noticeable. However, some of these issues can be fixed by adjusting the LEVEL control (clockwise) to turn the volume up of the subwoofer so that you can hear the bass sound a little more than before. You may also find different sources will perform better than others due to different types of audio compression and transmission.

      If there's anything we can do to help or you need technical assistance on our product in the future, please email us at socialsupport@am.sony.com with the following details so we can best assist you.
