So my VP100 & M22 are in the mail, and in the mean time I'm wondering about mounting them on my "typical" drywall wall. I am sure I can get a stud for the VP100, but I'm not sure yet about the M22's. Can these speakers be mounted using the bracket only screwed into drywall? I have seen the mount for the VP100 and it looks like the mount is wide enough so I can get at least one screw into a stud, but I can't tell how the M22's mount (but I'm guessing there isn't much room left and right with the M22 mount since the speaker is hung vertically). So if I can't get a stud for the M22, are there wall anchor's available that will work with the mounting brackets for the M22?
