A few years back I rewired the woofer panels on my 2.5's. The wires were beginning to come loose from the mylar en mass so I set out to rewire & re-glue everything down. Got one panel done but half way through the other, the old 23ga aluminum wire had a little more flex than it could take and it snapped on me. I made a repair, finished the job and everything worked so I thought I was in the clear. Life was good, I was enjoying my Maggies but slowly the imaging started to move over to one speaker. After troubleshooting everything I measured the speaker resistance and found one was measuring at 12-ohms! Since it was winter, I got distracted by the dark side (box speakers) and dallied there for a while. After blowing both EMIT's in my Infinities, the voice of reason said get out the re-wire kit I had previously ordered from Magnepan and get on it. After all, It was just one panel that needed repair. A tedious job for sure, but the hard part is done.
While the 3M 30F dries I'll put my stands back together and assemble the crossovers.
It's been a few years, but the Maggies will sing again TODAY!

Thinking back a few years ago, I remember seeing some posts where people with certain Maggie ribbon tweeter models (like the 2.5R) were mounting the ribbon tweeters on separate panels, placed next to the woofer panels. This was to isolate the ribbons from vibrations and allowed the ribbons to be aimed at the listener independently of the woofer. This seems especially useful in a smaller room.
First crazy idea of the winter. Carefully cut the speaker between the woofer & tweeter then join the panels with a hinge. This wouldn't do anything for isolation but it should help the imaging and soundstage in a small room.
Any thoughts?
Which ever way this works out, I'll know whether to make my ( coming this Spring I swear ) hardwood frames one or two piece units.

Don't chop up the original frame. Get hardwood boards and build a new frame with good rigidity and some thought put into securing the bass panel eg. in a clamp between two frame layers so that the structure can drain vibrations from the magnet board. Then do a separate narrow frame for the ribbon.

This is where I usually chime in and say " Too late, it's already done , but not this time. Having made hardwood frames for my MMG's, I can tell you there ain't nothing sacred about Maggie MDF spring boards, uh, panels.
