Default Rare Snell Type 1 - Broken Tweeter

I have a pair of these excellent speakers.

After years of enjoyment, the right tweeter gave up.

Wire from the voice coil to the negative post is broken, but I also cannot get continuity across the voice coil. Damn!

There are no markings to identify this tweeter (just like the 10" woofer).

The front plate is 90 x 110mm and the voice coil is about 1.25"

The mounting holes are 9cm x 7cm.

Any recommendations on a repair service?

Thanks,
Dan

Too bad Speakerdoctor has left us. The clips on the woofer look like Peerless. You might inquire over at the Classic Speaker site. Maybe Audax with a rectangular face rather than round? Madisound could maybe help. Or Meniscus. Another thread brought these to mind just in the last week or so. A very original take on how to make music happen in an ordinary room. Do they have a little ramp that goes to the floor in front of the dome?

I see you are well aware of classicspeakerpages. Is the tweeter pole vented and damped with felt? Ferrofluid?
The ramp is not so little but I only ever read about these, maybe in Audio magazine

There's an article in High Fidelity magazine (these were on the cover Oct 1981)

These are damped with felt backing and ferrofluid.

Sounds like Dynaudio/Morel with a custom face plate

Speaker Exchange in Tampa ( Speaker Exchange - Speaker repair, replacement, recone, refoam, parts and diy kits. ) said the tweeters look like Peerless or Polydax.

I'll send them both down and report back on results.

The tweeters look alot like late 70s, early 80s Audax tweeters (polydax in the US). I might still have some of these, but there were a large number of variations with different characteristics. Without an actual number trying to find a substitute will be a crapshoot.

You have a working one you can get clues from?

One is working. It has dc resistance of 5.8 ohms.

These are hand marked 13E and 13P on the back of the magnets on masking tape if that is any secret speaker builder code.

The woofer is 10 inch in this 2 way speaker.

Would the High Fidelity article give any clues?

Thanks,
Dan

You are looking for a nominal 8 ohm tweeter. There were also variations in the number of voice coil layers, and dome material.

Likely best to find a pair of something close and then tweak the XO if needed.
