Why not horns?

I have a neophyte question. (I admit I have not read every
response in this thread, maybe it's been touched upon .)

For a smallish mid- or tweeter horn, mid in particular,
would it be desirable to coat the metal casting with
some kind of goopy damping/deadening material ?

I have some horn mids I bought long ago to experiment with.

Thanks !

Given that my Lascala's might not be the "perfect" horn system, it was amazing how much more I wanted to, and did, listen to music after aquiring them, and, with each and every modification. I still own many "other" speakers that have taken up space in 2ndary systems(sold more than kept), but the system that draws me in are the horns. Aquire a pair (Fortes are not much 2nd hand), although I prefer the Lascala over all other Klipsch at this respective price point. The bass horn makes a huge difference over others....Just my opinion. And yes, I have a child that went through college, as well as other bills, so I understand the monetary constraints.

Horns blow.

I still see Lascalas around under $1k. Altec A7 to me the better design also under 1k. Altec model 19s about 1.5k, K horns about 2.5k. All good loudspeakers lots of other options in horns under 1k if you buy used, pro-audio or vintage.

Someone is showing a great deal of immaturity, as well as showing up late in the game.
