I think that the FMB would give you enough standoff to use regular M22s, however, the M22 is not a light speaker and I would consider upgrading the mount inside to speaker with large washer and nut to hold the extra weight and prevent over tightening pulling it through. Reason being is that someone had a VP150, I believe, give out and fall off the wall. Admittedly it took 5 years and it’s possible the mount had been over-tightened and started pulling through from the start. But I would do it for peace of mind.
Though I haven’t gotten them yet I do plan to use FMBs to mount my M2 wide speakers one I stop being lazy and or tripping on the milk cartons.
Cheers,
Dean
