Remember the Magneplanars (1) don't involve any acoustic compromises since they're specifically designed for on-wall wall mounting, and (2) have no effect on the wall except a couple of screw holes, easy to repair with spackle if you ever want to move. No holes and no concerns about wall depth. The MMG-W (in pairs) and MMG-C center channel speaker (not appropriate for your needs since the manufacturer says it works best with a little space behind it) are available from Magnepan for 60-day trials with full return; you risk only the return postage. That trial (of the still-available MMG, a free-stander) convinced me of the superiority of Magneplanar sound enough that I've ended up with the larger MG-1.6QRs.
