I was going to say that! The ferrofluid replacement may prove to be the solution. Not difficult to do, just handle all the tweeter components carefully.
yes, I have had them apart and noticed the fragile thin metal ring on the dome that seats into the fluid. already cleaned the old fluid out so speakers ran about 3 hrs. since flutes in and tweeters re-assembled without fluid. I may be good to go with the flutes and just new fluid. may not post again until that done but still appreciate anything else you wish to tell me. thanks again.
