Hi Gang,
I have a VMPS LCR for my center channel speaker in my all VMPS home theater kit. It has the lower grade drivers made of ? materials vs the woven carbon fiber cones of the Megawoofers. I contacted Misco and they have a driver that is close overall with the obvious difference being six mounting screw holes vs four in the original.

Anybody have any experience with these latest version of the WCF drivers? Can I just drill new holes and drop them in? Any xo changes required?
TIA for any help.

These are sold but he lists the model number of the LRC woofer
I wonder if the 6.5” woofer used in the RM3o series 2 would work? It has a phase plug rather than a dome dust cap.
Perhaps others can chime in.
OK George, and thanks. So the one on the left in your pic is the MCM? Wooden phase plug?
