I have a pair of M2's mounted to the ceiling in a 7.1 setup. I used some 3/4 inch plywood and some mounts from amazon that I got for 20 bux. I tried a different set of mounts that just could not take the weight but the one I have now work great. I looked at the FMB's but they wont hold the M2 vertical only horizontal.
You can see in this pic the small 3/4 thick plywood that I screwed to the stud (they were running the wrong way) then I screwed the bracket to the plywood.
I used monoprice ceiling mounts and painted them white using enamel paint and to me they look great. Enamel white looks just like your white stove when applied . The thing I like about the mounts was that where they pivot in the middle it has interlocking teeth so the speaker wont lean down over time . The last set I had used a ball and socket with little allen set screws and they just could not hold the weight.
