ok, so i thought i had a great deal on a hsu stf-1 that would tide me over for a few months, but that has fallen through. i have narrowed my sub choices down to the stf-2 and a2-250(size is an issue, else i'd just buy the a2-300). both of these subs have 10" woofer, and according to most of what i've read, the hsu will sould better w/ music and a2-250 may reach a little lower for ht. whichever one i choose will be going into a smallish townhome living room for now. also, i'm considering placing the new sub as close to my seating as possible as the neighbors have already beat on the walls w/ just my current polk psw10. hopefully the close positioning will still allow a good bass response, just at a lower volume. my uses are going to be 95% ht, so music performance is really not that important. do you guys think the a2-250 would be the best choice for ht in a small to mid-sized room where space is an issue, or would the stf-2 perform better?
