    Performs extremely well in an outdoor (covered) venue. Provides big bold and crisp bass in an outdoor area that is 1,600 sq./ft. Bass fills the entire space. Very pleased with this product.

    I got this sub because it was on sale, as I did not have a sub in my set-up and was not being picky. This delivered WAY beyond my expectations for the cost to the point that one of my friends who regularly comes over to do martial arts made a comment about how deep the bass was without knowing I had recently purchased a new subwoofer.

    I took advantage of some Black Friday ads and decided to replace my home theater with a 7.2 Sony receiver and this subwoofer. I have been very satisfied so far. Where my old Yamaha would bottom out and crackle at very certain tones or loudness, this Sony has delivered with no issues so far. For the sale price, it's hard to compete with this unit!

    These subwoofer is powerful enough to fill a whole room. It has lots of connection types in the back, one for it's own dedicated speaker wire and another using typical speaker cable, with positive and negative plugs. This unit also uses electricity, so if you want less cable clutter maybe this model is not for you, Overall a great purchase!

    I bought two of these subwoofers for my 7.2 surround sound system home theater. They sound absolutely phenomenal. Because of everything going on in the world I did not want to go to movie theaters. So I figured I'd bring them home. Now I have a theater feeling in my own house

    Connected to new Denon home theater and activates auto when there is a 5.1 or higher sound coded from Dish or internet. Good sound and was surprised to find speaker hook ups in the back to extend audio. I don't use additional extensions as have 7.2 surround to wall plates that feed wall mounted speakers.

    For the price I guess you can’t complain but I bought it to fill out my powered Klipsh bookshelf speakers and found it just dulled the vocals and instruments. I tried a few different positions, keeping it near a way to try and get the most out of it. I wanted to use it for recording so this just didn’t work out for me. I can say that it delivered when I threw on LL Cool J and Too Short. That’s why I am giving it 4 stars.

      Hi Cannon, we're sorry if the bass sound quality of our SACS9 subwoofer did not meet your expectations. We will have this opportunity noted as we always strive to make this a better experience. To improve the bass sound quality of this subwoofer, please ensure the connections have been correctly made. You need to turn the LEVEL clockwise to turn the volume up of the subwoofer. You may also find different sources will perform better than others due to different types of audio compression and transmission.

      Thank you so much for the 4-stars review and for choosing Sony!
