Measuring low resistances becomes tricky, as you can check by shorting the test leads of your DMM together and see what reading you get. When set with a range low enough to read typical speaker impedances even the resistance of the test leads becomes a factor, as well as how clean the speaker terminals are, and how good a connection you have on them. So we're talking Ohms in the above test? It seemed like you switched uF for Ohms in one of the other posts. With the readings you have here it seems that the T35B's (which you previously stated were labeled as 16 Ohms) have both had their diaphragms replaced with 8 Ohm ones. The mids also appear to be 8 Ohm units. It looks like the original crossover is not appropriate anymore, and certainly the tweeter L=pad/treble control will not be either if they are 16 Ohm units, as turning it up or down will actually change the crossover frequency as well as changing the volume of the treble. The terminals on the mid and tweeter should be marked, look for the color of the washers at the base like on the woofer (though they may be faded by now). Some EV drivers are marked T1 (+) and T2 (-), some had push open spring loaded terminals with red or black plastic caps.
A correctly designed crossover and appropriate L-pads will certainly improve the sound of these speakers.
