I dug the EPI tweeters I have out of the driver drawers, figure I’ll try and run limp on them shortly. Here they are with the Dynavox woofers I plan on pairing them with:

I wonder if I’ll need human speakers to rebuild them, one has a little damage showing and this version has ferrofluid IIRC.

They are stamped Dec, 1979 on the back:

I’ll post in this thread as I slowly figure this build out.

I only have a year on those tweeters. Darn!

I’ll be watching your progress…

Figuring an easy place to start, I put the Epicure ‘air spring’ tweeters on the limp jig and ran a stepped sine:

Looks like an initial pass, guess the ferrofluid is likely ok. Listening to the sine tones, they sounded fine to me.

Interesting too, the resonance seems like 1900-2000, which is the crossover point of the Epicure 10 speaker they came from.

I’m just going to move forward using them as is, and see how this works out.
