    What a difference this subwoofer has. I had a Kenwood subwoofer but this one blows out more bass and the sound is incredible.

    Been eying this for a while to upgrade my system to 7.2. Price down again, so I went for it. Totally forgot to pick up a cable for it though, something else to research for the buck. If all works well, then I will add second sub (and cable) to receiver.

    Nice bass for the size! Def recommend Don't expect the same bass an 10" or 12" will give you. Best suited for average size living room...bigger living spaces may want to roll with 2 of these.

    Room filling base. We have a 22x24 living room, hardwood floors, and this 8" does everything we needed it to do. I need to add speaker spikes as it hits so hard it crawls and will unplug itself.

    I replaced a slightly defective Martin Logan subwoofer with this sub and am extremely happy. Great bass without being overwhelming. Easy to hook up and adjust.

    I was advised by the Geek Squad to "step up" to the next level sub woofer for just $100 more…And it literally sounds like a thunder storm is approaching!

    was replacing subwoofer 1000watt which was too much for the room. Best buy rep helped with finding the subwoofer I needed, saving me some money. Plenty of power/sound for the room
