I did not have room in our 2 bedroom apartment to place the 634-VAC in front of my media center so I found this wall mounting option that works quite well:

(caveat: PM600 mounts into two adjacent studs therefore in my set-up the 634-VAC is visually slightly off-center a few inches over my 56' Samsung DLP. Can't move the DLP without pushing the tower speaker into the hallway beside the living room wall. Sound is EXCELLENT though.  Centering is something we will correct when set up the Home Theater in our new house ;-)

Peerless PM600 MULTI-MOUNT Heavy Duty Universal Shelf

This space saving wall mount is ideal for stacking A/V equipment such as DVD players, receivers, CD players and VCRs. This convenient unit is adjustable in width and depth and can support up to 49 lbs. It holds multiple electronic components in a compact format and even comes with a safety belt. We recommend you measure your electronic equipment to make sure it does not exceed the maximum width and depth ranges of this unit.

Features:

• Adjustable width up to a maximum of 20"  (The two "L" shaped arms make a perfect "shelf" at 18-20 in. width to hold the 634-VAC)
• Adjustable depth from 13.5" to 19.5" (13.5" is more than you need so the two arms "stick out" )
• Includes safety belt
• Comes with fasteners for wood stud walls
