    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

    Very good bass sounds, however, it’s a little delay in auto power on it takes for the volume to go up for it to come on.

    I should have bought two at the sale price. Nice complement to my stereo system in my garage gym. Bringing up the low frequencies makes the music sound much louder and richer without having to crank up the volume overall.

    Bought a house with built in speakers but no subwoofer. Didn't want to spend a lot, because may eventually re-do all audio in the house - this fit the bill

    I bought a new TV and receiver to use with my old speakers. All of the speakers worked, except for my sub. I tried different wiring, but never could get it to work. So I bought this one for $159. I am very happy and it adds that sound that I was missing.

    Sound is tremendous. Room filling bass. Best part is that speaker can be adjusted to automatically shut off/ on when no signal is received. This took a little getting used to while watching movies. But definitely a nice feature.

    Upgraded from an “all-in-one” Sony surround setup to individual components and the sound is so much better. More deep and immersive and goes with projector nicely. I’m using two subs for better performance.

    Got this woofer for under $100 and think it's worth every penny. Perfect for small and medium sized spaces. I'm using mine in a home office, paired with Edifier bookshelf speakers. Nice rich bass with no distortion. Would recommend!

    we purchased the Sony Subwoofer a few weeks ago. Our previous one which we had for about 8 years, also a Sony, finally gave up. Needless to say, another Sony was the obvious choice. And as expected the sound quality is fabulous.
