Can't seem to find a review of that sub that isn't very positive. I'll be replacing a BIC F12 that is bloated and boomy. It can't hang with my Martin Logan Electromotions anymore. The XS15 narrowly beat out the HSU VTF-2 MK4 and the SVS SB-2000. I listen to music/movies 50/50 in a 13x13 living room. Any input before I take the plunge is appreciated.
