Sry about not posting the speaker positions, but L+R are roughly 3ft in from the side wall and front wall. The center is on a shelf above the tv centered of the L+R speakers and the rears are roughly 5ft from where i sit in the corner in front of the bass trap. After playing around today, i may of found the problem, i calibrated using the receivers test tones this time which my settings were off by few dbs, but what was really off was the sub level. At nearly 10dbs off, the bass had returned with full force, so what am i missing here? The WOW disc said to calibrate the sub 3db hotter than the other channels and like i said, the test tones were plenty loud, but when it came to movies, the bass just wasn't there. Is my receiver inaccurate by setting the sub trim 10db louder and just never noticed any stress since i run dual subs?
