    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.

    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.

      Hi TechIT,

      That's awesome! It is really nice to hear you're satisfied with the amazing bass sound quality of your SA-CS9 115W 10” Active Subwoofer. You’re going to love the room-filling sound that Mica-Reinforced drivers can deliver. You’ll experience deeper, more precise bass reproduction than ever before and be amazed as your music and movies come alive!

      Thanks for purchasing our SA-CS9 and for choosing Sony!

    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.

    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!

    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.
