    I would give a 5 star except one pesky nit pick. I wish there was a way to increase the amount of time before it auto shuts itself off. I usually mute my sound bar during commercials. During that short time it cycle's off. I'm just afraid that it may wear itself out. I don't know, guess we'll see. You can turn that function off with a switch but that's why I wanted that feature cuz it's in a tight space to reach. Other than that it has separate adjustments for volume and Hz control which allows for nice fine tuning along with your sound bar adjustments.

    It’s a great starter sun and really sounds pretty good, but when I compared it to other subs in the same price range in my opinion it did not preform as well as the others.

      Hi keeneland101, we're glad you like our product. 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
