I know these sorts of questions come up all the time and there is no easy answer...
I have a set of Australian Axis speakers - LS88 and LS28 and a matching centre. The high frequencies on the LS28 and LS88 have all but disappeared - which I attribute to the aging Tonegen tweeter (94L65DS-03HD; 442TND).
I believe these tweeters were used in many speakers through the ages.
There is even a thread on re-doping them (or a very similar model):
How to Re-Dope Snell Tonegen/Foster Tweeters (Model E, J, K; gens. I & II) | Audiokarma Home Audio Stereo Discussion Forums
In addition to the re-doping, there is also ferro fluid that may or may not need to be replaced depending on if or if it isn't in there. In any case, I'm not sure if I'm up to taking these apart.
Anyway, have been looking for a replacement - unfortunately they have an in between cut out diameter (~94mm) and the LS88 has an extra magnet glued to the back..
Any ideas?
