I'm mounting two RB-3s on my back 'wall' (extends 15 inches down from ceiling). I've looked online for hours trying to find brackets that have everything I need- downward tilt (where the speaker will be postitioned I need as much tilt as I can get- up to about 45 degrees probably) and they need to be able to swivel left and right a little. And, of course, they need to fit the RB3. I've looked at Omnimount (75WA-IFK looks like almost perfect) but I'm not sure if they'll work- I wasn't able to see if they swivel L and R and actually fit the speakers. I've also looked at the Vantage Point bookshelf brackets but don't know if they'll work. B-Tech makes side clamping ones that I know could work, but they only tilt down 15 degrees (and their weight limit is right at where the RB3 is- 15lbs).
