Hi Bans25,
As Jakewash has pointed out, the M22s can be placed as close as 1 inch from the wall behind. You could consider a pair of M22s mounted to the wall the Full Metal Bracket. When I did the double-blind listening tests to the W22s vs. the M22s wall-mounted with brackets, I was amazed at the bass output of the M22s (no sub was running and I thought there was. . .).
The W22s are very, very close to the M22s tonal balance. If you used M22s with the wall brackets, you'd have the versatility of being able to tilt and swivel them for an ideal soundstage.
Regards,
Alan
