(Part1.)Great sound, and performance to cost. I have only had the sub for one day and am still experimenting with room placement, but it does fill my 15'x15' room with better than movie theater bass. My room naturally does not have good acoustics, so the performance is going to be affected so. The size and weight does make it fairly hard to move it around, but for me, i am willing to sacrifice ease of movement for performance. It preformed well on some bass heavy songs and bass testers and on some movie clips. I need to do some further evalluation on how accurate the bass is( remember my room has poor acoustics's). So far i have had a problem with things in my room shaking, like the door knobs or other speakers banging against the wall. I have A LOT of loose things in my room, its very cluttered, so that doesnt make for good sound. I have to clear out every thing that is not tied down to reduce rattling so i can hear the bass clearly. Ill get back when i have fixed up my room.
