    My grille pegs are about 0.488" in dia. but perhaps they will stretch. I'd be willing to put some testing time in on those if you could enclose 4 of them with my next order :D

    Those may be and improvement over the factory dome backing pads on the Peerless silks and RD0 silks. I found a couple of them detached when I opened them up.

    The M&K tweeter looks like a sticky dome.😁
