I have a pair of Black Satin KLF-20 that are NOT consecutive serial numbers but both untouched.
According to sticker on the tweeter horns, one speaker was made in March of 1998 or after and another one is from August of 1997. Newer one does not seem to have any issues but older one does.
1. Mid horn cracked from threading it too far.
2. Front (motor board?) panel is loose and wouldn't take much to remove it.
Crossovers and drivers look identical between the speakers.
My plan is to re-cap crossovers, repair cabinet(s), repair or replace cracked horn and soundproof both units.
Soundproofing is where I need some advise. Foam stuffing is different between speakers and I'm sure there are better ways to silence those cabinets. I read here that people use material called Dynamat?
Does whole inside of the cabinet need to be covered with it? Are there different thicknesses of this product?
Before I read about Dynamat I was thinking to use foam drawer liner material from Home Depot. It is about 3/16" thick but does not have adhesive side, so I was thinking to use carpet seam tape which sticks to about anything. I'd like to hear suggestions.
Tweeter diaphragms. Should I consider replacing them with Crites Titanium? Big difference?
Mid diaphragms. Anything to improve there?
Anything else?
Thanks
