I have looked at the links to Pinpoint and Omnimount and they both look good for the job. Only a minimal distance from the wall is required (about 2" is loads). We are also in the process of developing a wall bracket for these products but it will not be available until the spring. Both the M3s and the M22s can have screws installed in the cabinet without risk of damaging the speaker. I would suggest a screw that has about 1" of thread in the cabinet and definitely predrilling the holes.
