Epi Speaker Dating/ Serial Numbers - Emblem/Badge Changes

Two Steps

Has anyone found any information on dating Epi Speakers - specifically the 100's and all of their iterations?

I mostly am trying to figure out which logo/badge/emblem to source for a pair I am restoring.

Also, were Serial #'s chronological or did they start over per each version (e.g. 100v, 100w, m100, etc.)

Thanks!

There is no M100 per se. The M simply calls out model 100. There was a 100 and a 100V the only difference being walnut veneer vs vinyl which is what the V called out. In the beginning the serial numbers were sequential per model.

All of the walnuts had the original circular EPI logo like my avatar. I'm sorry I can't recall if it was exactly when the 100Vs started shipping, if not it was very shortly thereafter they went to the square EPI letters with the little sine wave thingy in it.

Huw may have exact time frames for you.
 
I asked Huw and he couldn't quite recall. I have the 100V that have a very low serial number - 3717. They also have the beefier cab - albeit still with the vinyl. It also has the Masonite woofer.

I have scoured the interweb looking for V's, W's, and regular 100's comparing serial numbers, woofers, and grill cloth. I seriously can't figure it out.

Were all the sine wave plastic block letters glued AND pegged in...? Because my grill cloth does not have a hole for the peg...

You're putting too much thought into this. The grille cloth appears to be original and the logos you need are the square block letters with the sine wave. I don't know what you are referring to regarding a masonite woofer. If you mean masonite tweeter, yours is the second generation tweet with the full size magnets and the leads entering at 180 degrees. The thought behind tweeter lead position was to have equal mass distribution on the tweeter cone. With the leads both coming in at the 6 o'clock position the thought was then you would have a greater mass on one side of the tweeter cone. By moving the leads transient response would be improved.

There actually were no 100Ws. When the 100Vs were introduced as a cost reduction step people started referring to the original 100s as 100Ws to differentiate between the vinyl and the real walnut veneer. The original 100s had walnut cabs, a butyl rubber surround woofer and the tweeter had the leads entering about 10mm apart at the 6 o'clock position. The grilles were hot glued to the cabs, not velcroed. The speakers pictured here appear to be from about 1975-76.
