    Plugged into the receiver, used the included audio cable and got just the low end kick I needed. Took a little bit to tweak the level, but I don’t need to once the sweet spot was found. Hood value for me.

    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.

    Reasonable priced SUB. Sounds great! It doesn't turn off automatically... if no sound is detected after awhile though...? It, does have a switch on the back. I, just hooked a smart plug too it instead.

    When this thing goes on sale, and you need one. GRAB IT. It makes sound so much more wholesome. Yes, there are bigger and better ones out there, but for the price and value of what I paid for it, I'd buy it again if it blows.

    Great value, to add bass, to your system. Watch for special pricing. to make the acquisition even better. Use careful attention when adjusting the cross-over and volume dials, to optimize the clarity, and to minimize distortion.

    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.

    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.

    Sony 10 inch Core subwoofer has 115 watts of surporting bass to match your specific speaker set up. Perfect for a small room, gaming, movies, wirh good bass sound. A little pricey, but it is a sony subwoofer after all. When a 12 inch subwoofer is too much for your space, this cone firing sub will do the job. I always know Sony products are good quality equipment. Basically a plug and play speaker with little to no adjustments.

    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.

    I've never owned a subwoofer before because I don't think they truly represent the music as recorded as well as a well balanced set of speakers. However, I never sit down and solely listen to music so I wanted something that would boost the bass spectrum across my living, dining and family areas to compliment my 3-way Sony bookshelf speakers. The key to these speakers is the pass filter that allows you to dial in the right frequency for a specific listening area. They are killer!

    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!

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.

    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.
