Yep, one FMB attached to the back of the speaker (yes, I drilled holes much to my dismay, but after asking Amie et al for advice)and to the bottom of the cross-piece/shelf. THe shelf is about 1.5" thick, so I was able to screw the bracket in using 1" screws. I was able to get a very tight & snug fit so that the bracket was completely invisible.

Email me if you want some more info/details. I would send you a photo, but I've since changed things around after I got my 42" Sony.

Take care,
Rich
