Why not horns?

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.

Noseplums - That depends on the horn. . . what is it made from? How large is it? Does the material seem to resonate when playing?

In general, I suppose the answer is yes, but coat the outside surface only. Coating the inside would alter airflow and corrupt your wave.

Mrdecibel, is it the showing up late, or the immaturity, that is the problem with Face's post?

If the former, he probably missed your invitation to join at a specific time in his inbox. If the latter, I take it as an amusing joke. Have you been moderating these forums, and keeping the members on time, for a long time now?
