Photon,
I'm about 5 feet from the wall behind me when seated, behind me is a row of cabinets and a counter. The space above the top row of cabinets have been stuffed with insulation then the space have been sealed of with cloth creating a very nice bass trap. Its about 12" deep 24" tall and about 20 feet long.
I read the OP was wanting to treat the wall behind the speakers with something to create depth in his soundstage my reason for suggesting the RPG or similar
As alway, Good Listening
Peter
