    I am going to roll out some adjectives like brawny, hefty, mighty might to describe this SONY sub-woofer. It replaced another brand and it was money well spent. It provides a great distortion-free bottom to my recorded and streamed music as well as movies, television and other streamed content.

    I purchased my first Sony AV Receiver in 1992 and it did not have a subwoofer. This subwoofer is a perfect match for my new Sony AV Receiver. It really fills the room with clear thundering bass.

      Hi zz30fg, Great! We're glad you like your new subwoofer. SA-CS9 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 choosing SONY. ~Earl Sony_US

    Works as advertised, Nice unit. BUT...it's heavy, however, all of them are. The controls for volume and frequency rotate too easily. It's too easy to change their settings by accident. Everything on the back should be labeled in a contrasting color like white. I have to use a flashlight to read the printing.

    I hooked this unit up to my system and it rocks the house. I like the fact that I can leave it plugged in and turned on it has a standby feature that shuts down the amp until it sees power to the speakers from the amp.My old Infinity sub amp blew up because it didn't have this feature.

    Had my old Sony 10" sub 20 years now , still kicking. I retired it to the rear on the 7.2. Put this little guy up front and couldn't be happier, fills the room nicely and doesn't bottom out.

    First of all, I’m not sure if my issues are from purchasing an open box item. But the power saver option doesn’t work as indicated. It’s suppose to shut off when not in use- but most of the time it shuts off and on during use. The power delivery is weak and the low range is not there. Bass gives strength and warmth to ur music but this ain’t doing it. It replaced and old Sony bass box which was half the size and less watts but sounded way better. Unfortunately I had to get a new receiver and the old bass wasn’t powered. Look elsewhere

      Hi Pets,

      We are really sorry if our SA-CS9 115W 10” Active Subwoofer didn't live up to your expectations and that it had to be returned. This is certainly not the news we'd like to hear from you.

      Regarding the auto power-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. This feature can be turned off by sliding the POWER SAVE switch on the rear panel to OFF. And depending on the audio source, the bass sound of our SA-CS9 may not be so noticeable. This can be fixed by adjusting the LEVEL control (clockwise) to turn the volume up of the subwoofer.

      Your feedback matters to us as it helps us improve our products. We are sorry for the inconvenience, and we hope that you'll consider Sony again in your future purchase.

      Sincerely,

      Romeo Sony_US

    No issues at all. I bought this to replace a 20 year old Polk. This Sony sounds almost as good. But I expected that, as the Polk was a higher end sub. I’m using it for a 5.1 surround system just for watching movies.
