I want to thank Jeff Hedback for his input and Dave and Gregg from PI Audio for their help and acoustical panels.
As my system improved I noticed that the right sound stage seemed not as forward as the left, with Jeff help I verified that it was the lack of acoustic panels on right side of room. At the time Jeff did my original acoustic consultation it wasn’t particle to put panels in front of wood stove. With Dave and Greggs help I designed removable panels using their acoustical panels.
I now have a balanced sound stage that starts about 2’ past each speakers and arches back and up to about 5’ high at the very back of the room.
Wife still needs to dye fabric to match other panels. My deal with wife is I can put up any acoustical treatment, but she gets to cover them with her choice of fabric color and design.
I built box out of 1/2" ply and 1x6 put dampening on back panel, covered it with foil faced denim insulation with 2" air gap between back of PI Audio panel and insulation.
