Hi boat,
I think I emailed you about this. Drywall anchors, those little plastic things you sink into a hole you drill in the drywall, then you put in the screw, and it expands the plastic drywall anchor. They work fine. Years ago, I used those to wall-mount a heavy pair of surround speakers in a house I owned. They were much heavier than the QS8s. Your plan for the cherry is a nice idea, but it isn't necessary. Glad you like your M22ti's.
