Default Repair?

Hi,

Mine are starting to go on some days. Click the image to open in full size.

Moca Audio in France will repair them The cost is 60 euro/tweeter plus shipping cost.

I purchased another pair on ebay with the idea of having a go repairing these myself. So far I have discovered that there is a screw in the middle of the rear (covered by a label) if you remove this, air can be pumped through to re-pressurize the dome.

What I need to do now is get a piece made that replaces the screw with a hole down the middle, I can then attach a tube with a cycle valve.

Watch this space!

with just 2-3 turns in this screw, you can pump in air (gently - you can do it with your mouth as well) and have a timeframe of ca 4-5 seconds to screw it tightly afterwards. Experiment a little and you will be able to do it easily
I managed to rescue 4 pairs of them, which I thought (for years) that were forever lost.

I wonder if there is a carburettor screw that could do?

The screw size is 2.4mm and the hole to be no more than about .5mm.
When the weather gets warmer I will have a go at making something in my workshop.

thanks for the info guys.
my tweeters still have output but it is low in level.am i right in thinking they are deflating because i can see the wrinking around the edges of the dome.i can still feel there is some pressure when i gently touch the middle area of the dome?
also do you guys agree that these have an unusually sweet sound but lots of detail.i have not heard these when fully inflated as they were in a pair of used speakers that i bought.

Hi fransiscan, your tweeters are definitely deflating... it happens to them all eventually. You'll find the detail will be fully restored when they are re-inflated although they will take a few days to get back the fluidity they are famous for. I hope you received my e-mail detailing the repair process, and take note of the caution on over-inflating. Once you have burst one, it's all over.
