Repair Wharfedale purple tweeter ???

Just picked up a pair of very cool Wharfedale w60c's. The woofs and mids are great. The tweeters are a problem and I'd like to stay with original if possible rather than replacing.

The glue has separated on the purple plastic tweeters.

One of the tweeters works (pics are of the non-working one). It's still wired but the voice coil is just resting in magnet - yet it works.

I'm thinking maybe I can just glue the plastic edges back down. How could I align the voice coil? Is there a high freq tone like is used to align vc's on woofers when re-foaming?

That leaves the 2nd tweeter. I'm thinking I can resolder the vc wire. It broke so it's not long enough. It looks like there's room to solder an extension because there's plenty of room under the plastic cone. Is there anything I should watch out for if attempting this?

I definitely want to try to restore them so I appreciate any advice.

btw - I had heard that Wharfedales had sand for weighting. In fact, the previous owner believed there was sand inside these. No sand, 1/4 plywood on both sides of 1/2" plywood for a full inch total. Very heavy and solid indeed.

If sand filled, it is the back panel only. The sides, top and bottom are of regular construction. Do a search as I thing the cementing of the tweeter has been discussed before. The tweeter you have is known for the delamination. The later tweeter with the grill corrected the cement problem.
 
I searched, but couldn't find any info on cementing tweeters. I'll keep looking.

I can't seem to get the solder to adhere to the voice coil leads on the tweeter. I sanded the ends pretty thoroughly, but no luck. So I'm off to the electronics store tomorrow to find some type of clip or something.
 
In an ignorant fit of impatience-induced resourcefulness, I used strong, clear finger nail polish to "re-glue" part of a membrane (edge) that had come loose from the magnet. Most of it was still connected, but part was not, so alignment was not a concern for me. I applied the polish liberally, but carefully. After it set and dried (you can tell by the lack of smell), I did a second treatment. It fixed it right up for me. (I have a nice set of W30DMkIIs that are on my home office desk as a daily listeners.)

search "Wharfedale purple fried egg tweeter" (or something similar) here (Google's AK search is sometimes better) and you might find more info.

Good Luck!
 
Was wondering if anyone would know if there are any tweeter diaphragm replacements that would fit the Wharfedales fried purple tweeters?
The voice coil is one inch.

THX!
