Regarding overtightening of the mount-to-speaker bolt- when I mounted my qs8's with the FMB's, the speaker kept wanting to rotate in relation to the mount and I found myself torquing that bolt more than I would have liked in order to get the speaker to stay put. I hereby suggest some "teeth" or friction surface of some kind where the mount mates with the speaker. Perhaps a rubber pad. I feel that would give a more secure (feeling at least) connection with less torque on that bolt.
