thanks all... offsets are pretty tight range .. front left and right are -1 and have ctr, rr, rl flat (0).... boundries all set to free..... pretty consistent room (approx 30 by 20) with wall to wall carpet; 10 foot ceilings; and only one window (i.e. the mancave).... have tried input sensitivity @ virtually every level.... purchased a non radio shack spl yesterday and that did not help either... thanks for all the help...
