When I stand in front of my speakers the bass tightens up dramaticaly and is louder in general. But when I sit down it goes away. Is there any way to correct this? I have my speakers towed out slightly and about a foot and a half from the wall behind them. They are also tilted back slightly. I found this setup works best for imageing in my room but the bass thing is the only problem now. I didn't exactly now how to do a search for this particular question so I figured I would go ahead and ask.
