I don't know what might be still available but since you are concerned about boring holes in the walls, I have seen stands for centre channel speakers that can be placed on top of a flat screen television(check Amazon.com). The stand is made by "Omnimount"(Model nbr. CCH 1B) The only issue is the weight limitation which would be a max of 15-20 lbs. The M2, in this case, would be OK.
