Ive seen threads like this before, nut I couldn't get a good read on what to choose. I have a $430 budget and am torn between these 3 subs. My room is a 10x10x12 with 8' ceilings. My use would probably be a 65% HT, 35% M. The a2-300 got my appeal first, but I'm hesitant due to its gigantic size. I'm in college, so I'll be moving it around a bunch.
