Hello Frank,
We'll have to compare notes. I had damaged one of the Midrange drivers. After an extensive search, I found these at Parts Express. They fit perfectly, have a built-in gasket, and sound terrific. I bought a pair for the rear mids. I am really tempted to use them in the front as well.
The original mids are brittle and fragile.

Coastsider clued me in to how brittle and fragile they are. I guess I lucked out, so far. I originally bought these for the Walshes, only I discovered one was open. Since I always wanted a set of WTLC's I kept them anyway. Then I learned how to fix the Walshes and now I have a full set for the WTLC's, a full set of early silver ones for my 2000AXT's and a full spare set for the AXT's. I also have a pair of fried ones in the closet. At some point I'll have to open them up to see if I can make a spare set for the WTLC's.
After I pulled the woofers I measured DC resistance from the pot wiper, through the "midranges" to the common point on the fuse. Measured something like 3.7 ohms, IIRC. That's with the pair wired in parallel. Those Vifa drivers you used look like they'd work well, except they are rated 4 ohms. Do they offer an 8 ohm version? Also no idea how they compare efficiency-wise. I suppose the impedance would be in the 6 ohm rated range with the tweeters pot turned down, provided the efficiency works out. Seem like a good choice for the rears.
Mine still have the vinyl wrap on top, though it's bunged up a bit on the rear of one of them (the one I have working now), plus it shrank a little on that one. Today I took a Sharpie to the thin lines of MDF visible from the shrinkage. The vinyl is in great shape on the other one. The front tweeter arrived loose on that one. After seeing your post on gluing them in I glued it in today and weighted it down with a spool of speaker wire on top of a drinking glass. Both cabinets have a bottom corner veneer chip. Old English Dark Wood Scratch Cover stains the exposed MDF nearly the perfect color to hide the chips. The veneer looks pretty good with just a coat of Scott's Liquid Gold. The original bases only needed a cleaning and a couple small spots dabbed with the Sharpie to look good.
I've only played one Debbie Davies CD at low volume so far but the bass sounds pretty good with the bases turned for side exit on the bottom woofers and the speaker out in the room. So do female voices, piano and electric guitar. I have a Qb playing on the left channel for comparison. So far I'm pretty pleased.
The grilles still need glued back together. I still have one more woofer to refoam before I can try the other speaker. Since mine had the original yellow poly caps on both the "mids" and the Walsh, I left them - at least for now. The tweeters pot only took a couple twists to play clean.
So, what's your initial impression of yours? What were you using before?
