    I would also find or make out of bolts, a 1/4" steel dowel and screw them into epoxy filled holes to locate the speaker.
    Hey thats a good idea. It sucks holding a 30 lbs driver with one hand while threading in screws with the other hand. Having the studs there and then just using nuts is a good idea

    Really compelling suggestion on the dowels and clamps. It really eliminates the tolerance stack-up that was building up close to the speaker cutout. Plenty of space and meat with the clamps (plenty far away from the edge). I went ahead and got the JBL MA-15 clamps. Pretty nice deal on eBay, and they look like an excellent choice. No need to keep fussing on that one.

    Sounds like you recommend steel dowels rather than wood?? Is the concern not getting the speaker against the rear face of the baffle and snapping off the dowel?? Better safe than sorry, I guess...

    .......then just using wingnuts...... and to make it easier still, make a wrench from plastic pipe. The one I use most is 3/4" dia. x 6" long with 3/16" x 1/2" notches. I started painting them dayglo orange when they began growing 'legs' and disappearing.

    Right, those or similar was what I was looking for. Surprised Google didn't find them for me.

    Well, threaded rod in my case after finding out how hard it is to cut the drill blanks used for 1/24th scale slot car drive axles; but yeah, something I can drop heavy drivers on without worry.
