    It’s just not powerful enough for larger rooms. I couldn’t hear the bass no matter where I placed the subwoofer and no matter how much I pumped up the levels. I think this would be fine in small spaces if you completely lack any low-end sound. I am using floor standing speakers and they produce enough low-end to drown out this subwoofer.

      Hi JacobPlano, thanks for choosing and purchasing our product. We're sorry to hear that you have an issue with your SONY unit. To obtain a better bass reproduction, we recommend you to install the subwoofer on a solid floor where the resonance is unlikely to occur. You can obtain a sufficient heavy bass reproduction from a single subwoofer. However if you use a couple of the subwoofers, you can obtain an even more effective heavy bass reproduction. Please follow this link for more details:

    It's a replacement for another subwoofer purchased that crapped out in just a couple of years and cost more to fix then buying this new Sony. Tried different brand this time.

    This sunny subwoofer is easy to use but not a lot of bass if you’re looking for it in a big living room area but it’s good for the price

      Hi Pioneerelite, we're glad to hear that like the ease of setup of 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. We appreciate your feedback. ˎIf the subwoofer is installed in the center of a room, the bass could be extremely weakened. This is due to the influence of the standing wave of the room. If this happened, move the subwoofer away from the center of a room or eliminate the cause of the standing wave, by installing a bookshelf on the wall, etc. Thank you for choosing SONY. ~Earl Sony_US

    Trying to decide between this and an Polk to complete my system. Couldn't be happier with my choice. Placed under an end table near a wall. Amazing adjustable bass lets you tailor it to the music you are listening to. Goes from subtle to room shaking and everything in between with a turn of a knob. Great speaker!
