Tha is what happens when you open your heart on Audio Fora..... We tear it apart .. I would try the easiest. Move your chair a good foot or more forward and toe in your speakers more. See how you like it and take it from there. it may be much more substantial than anything else as well as easier. it would take at most two hours, I would not go moving things around , sealing doors and getting involved in a whole construction project.
Don-There seems to be a growing consensus that my soundstage would be better if I got the equipment racks out from being between my speakers and move them someplace else.
After thinking about it, even if I closed the door into my workshop in and relocated the door to the other side of the wall, my gear racks still would be in the line of fire of the speakers and I don't think it would be worth the hassle of doing the work that would be involved. I will move my chair up some and see if anything thing gets better.
