I have a similar problem with my martin logan quest z's (for which a minimum of three feet from the wall is recommended. I placed ASC studio traps (www.tubetrap.com) behind each with good results. However, the speakers are still about two feet away from the wall. You might be able to get the Maggies closer than that. Good luck!
Speakers to beat wife-factor ?
I'm looking to replace my Klipsch Forte's with something more refined, but wife-factor requires placement very near rear brick wall, in a 12x14 room (England). Child-factor requires floor-standers -- boxes on stands wouldn't survive. Would like a Maggie-flavored sound, but is there anything that can deliver with its back to the wall and its feet on the ground? I want to keep the solid bass I have now with the Forte's, but want to improve the rest of the sound. Is my quest impossible?
