@BEC So no cotton at all. I hope i did not damage the tweeters. I put the diaphrams on last month when finally they arrived then i got them off since they where too harsh and bright on my modified and recapped kg4. Then i put them back yesterday, adding the cotton there was inside the old phenolic membranes. They played beautifully all day. I just stopped them now. I will open the mid-tweeters again and take cotton off. How do i see if they are damaged?
