I currently have my PB2 sitting behind a chair and I am concerned that the chair may be hindering the subs' performance. I have read a few posts with people talking about having PB2-ISD's set to 1/4 gain and -5 level in the receiver settings. Mine is set to -5 in the receiver, but I have the gain up to almost 1/2. Some people talk about having so much output that they experience the "fluttering pants" syndrome. Is this just exaggeration, or should my sub be doing this? I really want to put the sub in a corner, but my wife is a royal pain about it. She likes the reduced visibility the chair provides. I have followed Edward J M's setup suggestions to the best of my ability. As far as I know I have it calibrated correctly. Any thoughts?
