    I’m so happy I got it, worth it specially when on sale. If you get one give it a little patience In the beginning because it needs a break in period and maybe few adjustments on your receiver settings and that’s it. I like it a lot makes watching movies way better.

    Replacing old Bose woofer

    Works great. Not looking for out of this world sound, but needed to replace old Bose Lifestyle system because not compatible with new stuff coming out. Did not want to replace speakers installed in wall. After much research, realized this woofer would fit the bill and compatible with new receiver and tvs.

    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

    Purchased this to replace two MartinLogan subwoofers that had failed in a five year period. The first MartinLogan failed within two years and the warranty replacement SW ailed a few months after the warranty expired. Went back to Sony.

    I only had the sub for about 2 weeks before returning it. The sub didn't seem to hit that hard and at times I barely noticed it while other times I did but it felt like something was missing. The sub retails at $200, however, it was on sale for,$100+ I had a $50 gift card so I only ended up paying,$50 for it. The sub definitely is not worth $200 but at $50 it was worth the purchase. I took it back bc the Polk psw10 came back in stock and it was only about $80 after the gift card and it received way better reviews. So I exchanged the Sony for the Polk and paid the $30 or so difference. The Sony is fine if you have no other option it is better then having no sub. I will place a comparison review of the Polk when it arrives this week.

      Hi ghmcmur, it is unfortunate to hear our SA-CS9 115W 10” Active Subwoofer did not meet your expectations and that it needs to be returned. We’re not sure which brand of amplifier/AV receiver you have this subwoofer connected to, however, please ensure the connections have been correctly made. You need to turn the LEVEL clockwise to turn the volume up of the subwoofer. You may also find different sources will perform better than others due to different types of audio compression and transmission.

      We will have this opportunity noted as we always strive to make this a better experience.

      Hi sheffdog,
      Thank you very much for your recommendation. We're glad that you like your new Sony - Core Series 10" 115W Active Subwoofer. The Sony SACS9 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 your purchase and for choosing Sony! - Marco Sony_US

    I bought a Sony SW before, 20 years ago, and it still works great! This one is a bit anemic but since it’s for my second stereo, I am not that hung up on quality. If that was for my primary stereo, I’d spend more money to get the performance. But again, good value for the money.
