I put these into the studs and they're great for RC-10's! (and CB-20's FYI)

I also found drilling and screwing into the wall studs to be the right way. The "drywall" mounts would have worked for those tiny speakers but would not be safe for a 14lb one.
Thanks but the problem I had was specifically that there's not studs in my exterior wall. Just 3" of insulation (with wooden slaths on top, over which goes the drywall).
Maybe I should take time to show you guys what I finally did; maybe this could help others with RC- and CB- type bookshelves with threaded holes
So here's the problem area, where I have to mount an RC-10:
The ceiling is a tile drop-ceiling, the wall has no studs, so there's only the beam left, but it runs *parallel* to the direction where I want the speaker to fire.
This is my solution:
It's a sturdy 8-in L bracket for shelves. There's 3 5-in wood screws through the drywall and beam, solid enough to do chin-ups on it (if I was able to do chin-ups I guess). The bracket is installed with a downward angle (I couldn't do more with the space I have though). I drilled a hole (a bit too close to the edge, but it's still safe) in the bracket in order to be able to screw a 3/8"-16 bolt in the back of the speaker through it.
This is a picture of the speaker with the bracket but before mounting.
The tape is only to protect the finish. There's a washer on the bolt side, but nothing between the bracket and the speaker, so as to distribute pressure on as large an area as possible. In retrospect, I should find some sort of thin rubber membrane to put between the speaker and the bracket, to increase friction and limit vibrations between the tip of the bracket and the speaker. It does vibrate when I push the subs since it's so close to a room boundary.
And this is the end result with the RC-10 mounted. Very solid, and I think rather clean looking. I'm rather happy with how it turned out, and I'll probably use the same technique for eventual surround back speakers.
