I have my H.T. set up in a 14' x 17' room with the speakers about 8' apart and the Subwoofer in the right corner, about 6 inches away from each wall. About 12' back is my listening position on an L-shaped sectional couch. The couch is placed so I sit in the prime listening position on one end of the couch that is parallel to the plane of the TV screen and front speakers (obviously) My problem is this: In this position the bass from the sub is pretty good, but the lowest frequencies are a little weak here. When I sit in the corner of the sectional couch, I am sitting left of center of the prime listening postion but the sub produces the most even output here. The lowest notes can be heard with the most clarity. I have tried turning the volume of the sub up while in the prime listening position, but it only increases what I hear there already - plenty of mid to upper bass, but not enough low end. I have turned my sub in various postions in the corner, to no avail. I thought about trying the left corner of the room but the sub cable isn't long enough. Any thoughts?
My theory is that the sectional is acting like a "funnel" funneling all the lower bass waves into that corner of the sectional. Is there any way to adjust the phase of the sub to get better output at the listening postion? Any other suggestions? Am I suffering from a case of pesky room nodes? Am I crazy?
Speakers: Mission 774 Sub DefTech PF15TL
One other question: In theory, won't the strongest output from a sub placed in the corner be in the diagonally oposite corner of the room?
Thanks for your thoughts!!!!
