Hi All, After reading so many positive reviews of the SV subs I ordered the SVS 25-31PC+. It arrived yesterday - wow this thing is HUGE. I placed it in the corner where my older sub used to be and hooked it up to my Denon 3802. All speakers set to small, crossover at 80Hz as before, set gain level at about 1/2 and gave it a try. I played a couple of bass-heavy scenes and ... wasn't impressed overall. While the bass was definitely there and I could feel the vibrations I thought it was boomy, not tight as I expected. I know that I haven't fully calibrated it yet (will do this weekend), but I think the quality and tonality of the bass wont be affected that much by the calibration. I think it's probably the fault of the room's acoustics, but I can't really do much to change that. Does anyone has any suggestions or opinions before I decide whether I should return the sub? Thanks, RuslanM.
