I'm just wondering if anyone has used Omnimount 20s to mount RTi4s? I've done a search here and not come up with any hits. I've seen the BTech B77 mentioned and it looks like an elegant solution, but given the requirement of a stud, I'm not sure they'll work for me. Also, they're not available in white, but that could probably be solved with some spray paint. I had my previous surrounds (Rocket ELT LRS) mounted via the Omnimounts and also have 2x4s in the ceiling for that purpose, but in order to do so, I had to drill into the base of the speaker about 1/2" to secure the brackets. Polk tech support says no more than a 1/2", so to me that's cutting it a bit close. It would be good to know if someone else has went this route successfully. The keyhole mount isn't really an option for my either. Thanks for any help with this.
