Vintage EV ElectroVoice speakers

[OldMan]

I am looking at some vintage EV speakers.
I already have the woofers: SP15A
Midrange: Which is better, 1823M or 1824M?
Tweeter : Which is better by order T35, T35A, T350, T350A?

Thanks,
Ken

You may not get many responses on your questions, unfortunately- while I'm old enough to be familiar with those drivers, most of the forum participants have probably never heard of them.

By the standards we use today for selecting components for projects, there's little published measured data on the EV drivers (distortion plots, anyone?), and I've forgotten what I used to know about the differences in mechanical construction between, say, the T35 and T35A, though my vague recollection is that they improved the diaphragm material and support- but how it varies from the T350A, no idea. You'll probably find the two T35's interchangeable in a given design, as well as the two 350's, but not 35 to 350.

I did some consulting for EV back in the 70's, but it was electronics, not speakers.

Your best bet for information is probably some google searches.
