Congrats on the new speakers.

I just ordered a second set of M5HP's to replace my M60s but had that nagging "maybe this is where I should get LFRs" thought as I was doing it. One of my concerns has been clearances as well... it's been tough getting even the M60's far enough from the front wall.

What kind of spacing from side & front walls do you have ?

M60ti, VP180, QS8, M2ti, EP500, PC-Plus 20-39
M5HP, M40ti, Sierra-1
LFR1100 active, ADA1500-4 and -8
