    Great audio response and deep bass. I'm having an issue with Some things not triggering the sub from Netflix on Roku. I'm not sure if this is a subwoofer issue since other shows/Roku channels are doing great. As of now, I would recommend...which says a lot for me, having avoided Sony audio often in the past.

    Sub sounds fine, not as good as a $300 sub, but no where near that in cost. Good value.

    I purchased this subwoofer for my new STR-DH550 Sony Receiver and it's very compatible with each other. It sounds superb with my 5.1 home theater speakers. The subwoofer settings allows you to set a perfect bass sound for any type of set-up. This subwoofer should last a lifetime for any owner.

    Bought this to replace a subwoofer that had been purchased years ago as part of a fairly low cost home theater system. This is such an improvement over what we had - it sounds great and we are really enjoying it. Doesn't crackle like the old one.... Made me want to replace some of the other speakers as well.

    Have this in my garage, 12’ ceilings and about 650ft2. IT sounds pretty decent although it struggles with low bass…mid bass it really shines. For $115 on Black Friday I couldn’t pass it up.

    I’m pretty happy with my purchase. This isn’t the loudest subwoofer, but this does a pretty decent job with the low end, and makes my system sound very balanced with what I have. I wish there was a remote to turn the sub on and off. The standby mode hasn’t worked very well for me. It would turn off ok, but has a problem turning itself back on when needed.

    This subwoofer is an excellent subwoofer for the clean quality low bass frequencies it produces. When you compare the price with the competition, this Sony subwoofer wins out. It's hard to find a speaker that does this good of job for this price.

    Bought a new surround system and the old subwoofer would just hum. Tried cables, connectors and rerouting cables, still hum. Bought this one and used the same cables and no hum at all. Love the bass sound too!

    When this subwoofer was hooked up to the sound system, it was magical! A rich, full sound emanated throughout the room. It was not overwhelming but balanced with the existing surround sound speaker system.

    I have two of these now... I had to get a second to max my receiver at 7.2. It sounds great; even on carpet it isn't muffled, and the second one, in a corner, isn't "boomy," either. They're a little quiet out of the box, but nothing a couple adjustments on my receiver couldn't fix (which you should be setting anyway).
