I got some QS8's from the FO recently. They came with the T brackets.
BUT - the brackets are designed to impossibly close tolerances, and if the corresponding brackets on the speakers are mismounted by even a fraction of an inch or a degree or two, they do not work at all. I grabbed a file and made the necessary modifications in 15 minutes or so, but was a little frustrated. The fine folks at Axiom said they are looking at a redesign of that part.
I would agree that the FMB is functional overkill and aesthetically worse than flush-mounting.
