Thanks, Bill.
I was going to look for similar size Klipsch grills and modify them to fit. Do the magnets attach to the inset metal screws? I took a magnet to the frame and did not find any metal that would allow the grills to attach. Are you using the bi-wire connections from the Yamaha amp or a jumper on the speakers?
Also, I see your list of equipment above...just purchased the new Rotel 1592 integrated amplifier (My Yamaha A-1000 amp from the early 80's finally quit). Class AB w/200 wpc. Had to run a complete new circuit to get amperage needed. Pure, clean sound through the Klipsch!...looking to replace my Definitive Technology Mythos and Gems II.
Good Listening!
