    I don't need anything fancy for the room I have and this sub packs plenty of punch. I had an old HTIAB sub and I can really tell the difference. Just watching regular TV I can feel the bass this puts out. Connectivity and setup to my amp was an easy process.

    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.

    The is a great sounding subwoofer but you have to make some adjustments. This subwoofer provides plenty of floor banging bass and clarity. The only reason I'm giving 4 stars is because the sub sits directly on what ever it's sitting on, this takes aways from the clarity. I have to get a subwoofer stand to clean to audio up.

    This sub is good. It wont make pictures fall off but its not quiet. Bass can drop low but you probably want to turn the subwoofer settings up on your receiver and adjust the volume on the subwoofer.

    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.
