    The sound quality of this Sub is great. I am thoroughly satisfied with this product. My only real gripe with it is that the length of the power cord is maybe four feet long. Naturally I needed five feet to reach the outlet, but I made things work. Otherwise, I am definitely satisfied with it completing my steroe set-up of a Sony receiver and two bookshelf speakers.

      Hi JohnA, 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

    Alex was fantastic. I came into the Best Buy store in spring hill, FL and the staff was very helpful in helping me find exactly what i needed. Not only did they help me get a better deal qith my premium plus membership but that saved me even more money than i expected. Very happy and very satisfied with everything best buy has to offer. Theyve helped with my smart phones, stereo systems and much more.

    I have an older surround system and lived for years without a subwoofer. What was I waiting for! My movie and TV watching experience changed the moment I plugged the subwoofer in. I'm glad you can put it anywhere in the room. The included cable was just the right length for connecting to my Amplifier. I'm glad I bought this.

    My Definitive Technology sub started buzzing and I needed a replacement. This Sony subwoofer is great at a significant savings over the Definitive. I feel it works better than my old sub ever did. I purchased this on sale and even at full price it would be worth it.

    If you need a subwoofer for a medium to large room, and you like action movies or music with extra bass, then I would highly recommend this Sony. This woofer probably could get 5 stars, although the only slight drawback is that it only engages when there is sufficient power (volume) to drive the cone, so there is no extra bass in lower volumes. If you want extra uumph in the medium to loud volumes, then this woofer is a great way to go.

    I use the subwooer for my 43" TCL TV., using the small class-D amp with sub-out and two desk top speakers. Now I have a nice balanced sound with clear strong low end from the system. I enjoy regular TV program and you tube music clips. I like this subwoofer very much.

    This SONY SACS9 Subwoofer connects well with the SONY STR-DH590 receiver. Sometimes, when the volume is very low it does not automatically switch itself on. Just turning the volume up on the receiver activates the auto-on feature. It can also be set to always stay on.

    Bought this bad boy to help with my new Sony 7.2 4K receiver and it does it's justice. Hearing explosions and making the ground shake or even when the T-Rex escapes his area in Jurassic Park never felt so scary. Pick this up if you're looking for a new and fairly cheap subwoofer.
