hi Paul

i had already Altec horns, and comparing them to wood horns, they really sound poor. What i really doubt
is if someone is able to hear the difference between  high gloss finish/ high porosity surface of horns.
I really doubt abought that. I  cannot imagine that there is a percievable difference.

Maybe you have access to lashes of stone at home or next to it. Get a well polished one and a rough one, without any "mirror-like" surface. Place one besides your speakers in the area of the 1st reflection and listen. Then change that lash for the other one and listen again. You'll see that being the same kind of stone (granite or marble is as good as any other stone for this simple test), the way it's polished and finished afects to great extent how the sound is reflected, the frequencies reflected and the amount of reflection. This rules too into a horn. I haven't tried horns and I don't know for myself how the horn's finish modulates sound, but I'm sure it must make a difference. I tend to be more confident on Romy's judgements than any internet reviewer's.
