Hi all back after a few year hiatis

just ordered a pair of M5HP I had the M22, but had them wall mounted.

just wondering for those that have these what are the best placements you are finding. I know these have a wall mount option but am wondering is that would be too close to the wall.
My room has treatments etc
11.5 x 15.5 x 8 the room size.

really don't want to put them on stands as the one spot is where my sub is best

Anthem MRX520
M5HPv4
VP160HPv4
QS10v4
