    This subwoofer exceeds expectations even in just a 2.1 surround setup. Just plug into the receiver and you are now set. Not to deep bass but enough to drive a decent loud home theater setup for any small or midsize room. Build quality is great at its price range.

    Great deep bass. I love that it detects when it is needed. It will turn itself off if there is no low frequency signal but then turns itself back on when one comes through.

    This Sony subwoofer was easy to set up. There were a few negative reviews of it. If you have the correct acoustics in your home, this sub works out great and is easy to use. You can't beat the quality of it for the price you paid.

    I am very impressed with the clarity of the bass I'm hearing with this sub-woofer. Although it does take a little floor space, the sound just makes it worth it. The price was very reasonable for the quality I received.

    Sony - Core Series 10" 115W Active Subwoofer - Black is a very powerful Subwoofer by itself, but paired with all the core series speakers and an extra Sony - Core Series 10" 115W Active Subwoofer - Black and the SONY STR-DN1080 is just ridiculously AMAZING.

    This subwoofer is replacing a non-powered one in a speaker set bought 20 years ago. This one requires its own power supply, has sound quality adjustment controls & rocks the house for sound & power. Like it!

      Hi Ruth, we're glad you like the sound quality 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. Thank you for choosing SONY. ~Earl Sony_US

    This subwoofer brings the boom! So much that my Wife thought it was thunder, lol! I adjusted it through my Sony Home Theater system. There is a slight delay when going from a quiet to loud sounds in a movie, but is acceptable because you get power savings when it's not in use. I bought this when it was on sale, but it would still be a solid choice at full price.

    We love our new sub! After many, many years of using a passive sub, this powered 10" blew us away. The only problem we have now is securing stuff on our walls so it doesn't rattle when we watch movies :)

    The Sony SA-CS9 Subwoofer works fine in my bedroom. It was easy to setup in a couple of minutes. My Vizio Sound Bar lacked the bass quality on its highest setting. The Sony Subwoofer completes the lower frequency sound for a good bass feel. The price was great for such a high quality item. I recommend Sony products anytime.

    This sub offers a nice design, easy setup, and loud bass. Easily incorporated into a home theater system with subwoofer cable. Knobs on back control volume and cutoff (50hz - 200hz). Another nice setting is power save mode, which will turn off the sub if no signal is sent from the receiver. The sub also looks nice and does not stick out like a piece of equipment, but as an accent to the room.
