I picked up a pair of Celestion Ditton 44's last week courtesy of eBay... I tested them at the sellers house all okay, wired them in at home everything was fine then that evening one tweeter decided to suddenly go open circuit :scratch:
A quick dissection showed the actual voice coil was black & crumbled to dust when touched so repair was off the cards ! After some hunting around the net it seems others have had similar problem & the suggested replacement is the Seas 19TFF1. Some clever chap over on diyaudio has calculated the necessary changes to the crossover making the Seas a proper replacement instead of a bodge.
Anyway, I've just ordered the parts so will update when they're here & installed - I thought I might as well do a thread on it as its a common problem & lots of people seem to give up & flog the speakers without working tweeters which is a shame.
This is the original crossover:
And this is the revised crossover :
Its also worth noting this is compatible with both Ditton 44 & Ditton 66 as they share the same HF crossover & 4ohm HF2000 tweeter... The Seas 19TFF1 is a direct replacement for the HF2000 whereas the Hiquphon OW1 would be a major upgrade in sound quality but thats not my goal
