In my quest for the optimum performance from my speakers I keep hearing from many that the first thing is to dampen the 811B horns.
I don't hear any ringing but I do listen in the nearfield and have some time to mess around.

Lots of info but what I need to know is where do I concentrate the dampening on the horns? Does it go on the back side behind the baffel, on the front side part that protrudes out, both? What is best.
Also I have heard alot about what to use but would like some advice from those who have found what works and is relatively easy to put on/get off.
Do I mix some tar type concoction, by sticky backed material, spray undercoating or what?
I do not wish to destroy my horns by cutting fins, nor do I want to destroy the looks of them by gooping up the exterior visible portion.
Don't know if others feel this way but at times I like to remove the grills and watch the speakers work while I listen, usually when I am getting loud, just seems to add to the pleasure.

Any help on this subject.

Thank you

Gary
