15'x20x'10 (lxwxh) I will say that the room is not a perfect square. At the moment, I am happy with it simply because I only have the tv and the sub I have no additional speakers, no receivers etc. However I do plan to make those purchases soon and I was wondering if this sub is enough.3
As far was what I want it to do, well I guess that is the point. I do no know much about this stuff so I can not really tell good from bad. Perhaps you can prescribe some test with some music or sound track that would help me understand a good sounding sub from a bad for perhaps more accurate, what I should look for expect from my sub.
