    I waited for this to go on sale because I really did not need it for my stereo system, because my from speakers have large subwoofers themselves. However, I wanted to check that box and I bought this. Works well except I need to figure out how to calibrate the auto on feature because it doesn’t always cycle on, when I want it on and have the other speakers working.

    I was presently surprised by the performance of this speaker. I bought this to replace a broken $700 subwoofer in my home theatre system and this Sony performs just as well.

    Loud

    This sub is very loud and reaches some lower frequencies than most of the subs I looked at. However, at loud volumes the bass does not stay crisp and clean. It can actually get rather distorted at loud volumes, which is a turnoff. I got this for $100 and don't think it is worth any more than that.

    It's connected to my sony strdh190 and it runs great. Only thing is that it gets a little hot on the top of the sub vent, but I'm not sure if thats normal or not.

      Good day, Bhavnoor!


      Thank you for purchasing Sony SACS9. It brings us joy knowing that you liked our audio products and we appreciate you for that. Regarding heating issue or the unit gets a little hot, normal operation should have the subwoofer feel warm but not hot. A faint odor is normal for a little while but not long-term. Make sure that your SACS9 is in a well-ventilated spot. If you feel the heat/odor is excessive or above average, please feel free to contact us and we'll be more than happy to assist you. You may send us an email at socialsupport@am.sony.com with the following:

    This item goes on sale on and off. It is a 6 Ohm speaker so remember to get the right speaker wire gauge and set receiver to 6 Ohms if necessary, and to update your receiver that you have a subwoofer.
