Hi folks I am new to the Axiom forums but have been an owner of the AX 1.5/1.2 speakers for quite a number of years (12+). I am looking at upgrading to the Epic Grand Master and have some questions re the M22 Bookshelf speakers. My Speakers will actually live in a built in wall unit on a shelf. The shelf is 12 inches deep and with the speakers being rear ported, I wanted to see if anyone out there has similar setup and whether or not the sound is affected by only being 3-4 inches from a rear wall. 3-4 inches cause I understand the specs are the speakers are 8 inches deep so in a 12 inch shelf, we'd be left with 3-4 inches behind.
