    This sub is great for small rooms. For larger rooms or for home theater I'd recommend a second sub or larger one.

    Got this on sale to go with a new Sony recover. I’ve read some bad reviews but this actually does a good job at putting extra bass in the room

    Could not connect properly and get proper sound from Edifier R1700BTs - they give slight some sound and they have Y splitter -and Sony have only 1 input RCA for specially LFE output. Pretty limited input-output capability for this price range. Quality looks ok but Sony brand wants too much for Name shield on it - feels like it.

      Hi there,

      Thank you for your review.

      We are really sorry if you are encountering an audio issue, and if the available connection of our SA-CS9 115W 10” Active Subwoofer did not live up to your expectations.

      We greatly appreciate your feedback.

      To ensure you have the right connection, check out the operating instructions of this subwoofer:
      https://www.sony.com/electronics/support/res/manuals/4533/45336601M.pdf

      Depending on the audio source, the bass sound of our SA-CS9 may not be so noticeable. However, you may try 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.

      Additional information:
      The SA-CS9 features an auto power on/off function. If there is no signal input for a few minutes, the POWER indicator lights up in red and the subwoofer enters power-saving mode. To turn off this power-saving mode, slide the POWER SAVE switch on the rear panel to OFF.

      If there is something that we can help you with, please email us at socialsupport@am.sony.com with the following details:
