My pb10 just isn't cutting it. To get the proper bass that I'm looking for I've really got to crank the sub and it's just farting and to boomy. I'm looking to to upgrade to a nice 12" in the $500 range. I've been looking at HSU's VTF-2 MK3, SVS's PB12-NSD and ED's A3-300. I've been reading about them in the forums but haven't really heard to much in comparison. Anyone have input on these options or would like to throw in another recommendation? The room is carpeted and about 3000 cuft.
