Paul,
The calculator I use is linked below. I still come up with 2.84 for the tweeter cap. Same as what was used in the Esquire 200 and Regal 300 with a 16 ohm T35B tweeter.
Using this calculator I'm also getting the 18-19uf for an 8 ohm midrange and that confused me from the beginning because the cap in there is 5.7uf and it appears to be original.
I think where we are getting crossed is that I'm assuming the tweeters are 16 ohms. Craig said at least one measured 7 point something ohms and that sounds like it is more than 8 ohms.
His 12W woofer does appear to have a number or letter stamped after the 12W like what EV did with the 15W/15WK Drivers to designate a different impedance for different enclosures like the Regency or Georgian.
And with the readings Craig provided I have to assume that the 300011 also has a 4 ohm woofer, 8 ohm midrange and 16 ohm tweeter.
In my friends EV Two's from around the same period I don't remember seeing any badge or designation on those mids either but I do know they didn't put out much. I even sent them to EV when they were still in business because I thought they were faulty but they said they were OK.
The woofers in my Esquires aren't marked with a model or impedance and they weren't in the usual EV lineup of drivers. I think they are 12BW or 12BWS and they are 4 ohm.
Seems to me that EV came up with some special drivers for some of these bookshelf speakers because they are infinite baffle types of enclosures.
The woofer is less efficient and the mid didn't have to compete so why toss in a more expensive T25 to only cut it back so much?
The T35B was already less efficient than a T35 so they probably let that fly because it did give you the option for more "sparkle" at the top.
That 4 ohm woofer, that may have a longer throw, must have lead to using
different impedance drivers to get a workable system balance.
Pure speculation on my part but I can't come up with anything else.
