Wall mount hardware for M-Audio BX8a's?

Please pardon if this question belongs in another forum. Can anyone recommend a source for brackets to enable wall-mounting M-Audio BX8a's? Changing the layout of my studio recently left me with no options for floor stands. To complicate things, the BX8a's are heavy-- approx 22lbs each, they're deep-- approx 14" with an XLR connector protruding from the back, and have no integral mounting hardware. Screwing into the cabinet goes against my better judgement, otherwise I'd likely try a solution like this: http://www.mountsandmore.com/asp/show_d ... MP2-OM0068 The monitors were obviously intended to rest on a shelf at ear-level (as I've used them until now), but my only option is to wall mount 'em . Thanks in advance for your suggestions.
