I'm looking for knowledge or advice on whether or not it would be a good idea to (dare I say it) drill holes in the back panel of my speaker cabinets to accomodate a mounting bracket. I'm attempting to position my Diva 2.1's on the back wall of my movie room and hope to keep them elevated as to not have them interfere with the rooms space. Can the weight of the speaker eventually cause a weak spot at the point of the mount? Any knowledge or input would be of great benefit right now, Thanks. Dan.
