Youthman, those look like they will workbut they say the will only accomadate only 11 inches deep speaker. I just measured the rb61 and it is 12.25 inches deep. What do you think?
"Handles a speaker from 5.5" to 11" Wide, up to 11" Deep and up to 20" High"
I am setting up a 7.1. RF82,RC62, RS52 for sides and the RB61s for the rears.
