Any chance of finding a new replacement for my CDM1 tweeters?


Their response has dropped significantly over the years, and after removal and inspection, the ferro fluid thick and "dried up" The speakers were never powered in excess. I think they are just old.


I used to love the sound of these, but now the lack of tweeter response is a real problem.


I keep checking this site, but the are continuously out of stock.

Are there any "alternate" brands that could be dropped in as a replacement?

Well, scratch that.


I took the tweeters apart again and was able to dig all the old dried up ferro "fluid" out of the voicecoil gap in the magnet. The gunk at this point is just mostly dried ferrous particles.


Sounds a lot better, with much more output, but I'll probably be looking for some new fluid, as the fluid was there originally for a reason, presumably to smooth response and help with cooling.

Hi,


I have the same problem with a pair of CDM

1 speakers. How did you remove the old ferrofluid, and did you ever replace it?
