Morel MDT29 Failure.

[hawkinsec]

Is anyone familiar with this tweeter? If so, is there any cause of failure which is more likely than any other in an old unit (possibly 30ish years)?

I can’t help with your question and am not familiar with your MDT29, but if you are looking for a replacement, Falcon Acoustics have a good selection of Morel tweeters. If you phone or email Gerry, he may be able to recommend a drop in replacement. Of course, you may need to buy a pair.

Greg. Thank you very much for the suggestion. I've been playing on ebay again and have made a bit of a boo-boo of checking prices of bits before bidding. I'm optimistically hoping that the item might be repairable, but will certainly contact Falcon if it isn't,

It is normally one of the two fine coil wires that break. Bob

Oh, nothing to do with ferrofluid then. That's going to be a few bob if I get them.

Eddie, thirty years isn’t a bad life of use. Trying to get exact model replacements or even getting it repaired maybe a false economy. I would firstly consider whether you can get a drop in replacement with current production and if you can, go for that long before considering anything equally old from eBay.

Seconded.

Hi Eddie, I'd try to get the exact one first if they are speakers that you care much about.
You've probably googled but Parts Express are saying they'll have them in at the end of the month so may be worth an email,

US I know, but see what they say.
Ferrofluid, yes probably dried out, but have you checked the coil with a meter?

Morel CAT298 Classic is the drop in replacement and available from Europe.

I have a pair of spare domes stashed away for the Morel MDT33s that are in my small "office" speakers.
I like that they do spare ones, a lot of makes don't I think and surprisingly reasonable price as well.
