RC85i Install Problem (Studs too close)
Help!
I ran into a problem installing my Polk RC85i's! Thanks to an inaccurate stud finder, I discovered that instead of my studs being 8 3/4" wide, they're actually 7 3/4" on the rear left wall and 7 3/8" on the rear right wall, which makes the mounting space too narrow for the RC85i's.
What's worse, is that the RC85i's have six rotating cams that help secure the speakers to the wall. But ONLY the bottom two will rotate vertically. The other four rotate 90 degrees to the right, which means they won't secure the speakers because studs are in the way. BTW, these are 2 x 6 exterior wall studs.
At this point I need to purchase another set of in-wall speakers that will be no more than 7 3/8" wide and at least 12 7/8" high and will either mount to the studs or have mounting cams that turn up or down. Man, I've really CUT myself into a corner this time.
Thanks in advance for your help.

I have an older home as well, so I feel your pain. The width isn't really an issue for a replacement but the cutout height is....I presume it's already cut.
I don't have a pair of cams handy, or a wall but you may be able to shorten the upper cams with a Dremel. You may find it's loose but should be able to place a shim, prior to clamping.
Do you have some pictures of the working area?CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint. -
I had a similar problem when mounting my Modernos in the basement, but the walls are nonstructural, so I did some powercarving

Actually the house is brand new. The problem was the builder pulled a fast one on me and shortened the distance between the studs, making it impossible to fit the RC85i's without cutting the studs, which I can't do because they're load bearing.
The cam problem doesn't really have anything to do with the depth of the cam, as much as how they secure the speakers. The only drywall I have to work with is above and below the speakers. The bottom cams will lock into a downward vertical position, but the upper cams only go horizontal. And since there are studs in the way, they won't be able to lock into place.
If it wasn't for the cam problem I think the TC65i's would work fine. -
Update: I examined the RC85i's closer and it appears that I can simply cut-off the end of the cam holder, which should allow me to rotate the cam to the vertical position. The only question now is should I order the TC65i's or LC65i's. BTW, I'm matching these up with Monitor 30 front speakers and a CS1 and the rear speakers will be less than 2' from a perpendicular wall. Thanks for your help.
