I bought this T5 Subwoofer to go with my Edifier R1280DB's bookshelf speakers. WOW! Great sound! I mean I was already happy with the 1280's but adding the T5 adds a whole layer of depth. I was so impressed that I moved them out of my office (was using the 1280's as PC speakers) and into the living room. Hooked up to the TV, the sound is fantastic. When the action in the movie moves from one side of the screen to the other, so does the sound. That cool stereo effect I was not getting from my old soundbar. Then there's the bass rumble from the T5 during the action scenes. I just love it.
