    I purchased this Subwoofer two years later after I purchased the SONY sound theatre package. I can see the difference with and without it because now the surround sound is always present every time I use the TV or listen to the radio.

    It produces deep bass, but there isn't a lot of power there. A lot quieter than I expected.

      Hi TimP, Thank you for the feedback on your experience with your SACS9. While we're glad to hear that you like the deep bass sound, we regret to hear that the power output did not live up to your expectations. To ensure optimal listening experience, check that this subwoofer and
      components are connected correctly and securely, turn LEVEL clockwise to turn the
      volume up, and check and recalibrate the subwoofer level on the connected audio system. Hope this helps and thanks for choosing Sony! -Sam Sony_US

    Maybe I just haven't found the right setting yet but it's not quite what I was hoping for. I was hoping for a harder punching bass to add that thump from the kick drum. But it definitely adds depth to the overall sound from the whole system.

    Never had one before so didn’t really know what to expect - had to tweak some of the settings on the receiver - set some speakers from large to small and change the decibels from -8 to 10. Now seems to be working fine.

    This subwoofer has a tight low end to capture and allow you to feel sounds such as thunder from lightning or the blast from a bomb going off or when listening to music the deep bass from a drum set and the rythem from a bass guitar.I highly recommended this subwoofer.

    Good sounding subwoofer but returned it due to clicking sound related to speaker sleep and wake-up mode. Purchased a klipsch subwoofer and wow…big improvement in sound.

      Hello JorgeA,

      Thank you for the review and it is unfortunate that the unit had to be returned. There might be a problem with the speaker connection with your speaker. Thank you for sharing your experience and we hope you will consider Sony again in a future purchase.

      Regards,
