The measurements you posted here on 1/12 listed the T35B you tested at 7.8 Ohms. If the driver actually was a 16 Ohm unit it should measure about 11 to 12 Ohms with a DMM. The diaphragm in that T35B has apparently been replaced with an 8 Ohm one at some point. The replacement diaphrams for the T35/T350 have gone through a spotted history. There were some off-shore copies around with dubious quality. EV sold the original tooling to make them to Great Plains in Oklahoma some time ago, but last I heard they had trouble sourcing the phenolic base the voice coil is wound on, and they were not offering them until they could solve that.. Bob Crites had been offering some 16 Ohm ones he claimed were original old-stock EV, but you need to send the driver to him for a replacement. This begs the question of whether your other T35B also has an 8 Ohm diaphragm. You figure the crossover based on what's actually in the driver, so the crossover specs I supplied for a 4 Om woofer, 8 Ohm mid, and 8 Ohm tweeter should be valid. The power of 1st order crossover design is now in your hands, and you probably have a calculator on your cell phone that can do the arithmetic. Forget the online calculators for this.

You'd have to contact Bob Crites about the cap holders ( a hot glue gun is used by many ; ) and the terminals. You'd have to ask him if he'll do a T35B and what it'll cost. I'd just keep the 8 Ohm ones if they both match.
