In the Thread: Practicality of paper mache horns.

"Gargoyle, YMMV, but I associate LF propagation/amplification with mass; there has to be some way to really "anchor" at least the LF driver. "

Noted

"I was thinking MF for the felt and/or paper horns, although I guess you could begin with a chicken wire form and build it up, ending with something heavy, like plaster. "

If I thought I could do a decent job bending up a wire horn, I may attempt it.

"Again, Jesse covered the plaster very well. As for surface treatments, this is yet another case where the site is rife with ideas on the subject"

I have been finding more information by using google to search the site. Forgive me if I haven't caught up on 100% of it yet. Things like this need the right balance of experimentation, research and inspiration.

I suppose in this thread I should just focus on the structural aspect of the horn but invariably at some point the surface finish will intertwine with the subject.

"My own thoughts have been to not ask much from the horns, but to try to use fast rates and some paper drivers."

I could see that.

" Still, I can't deny that the Cogent lower MF was among the best I ever heard, at least for one octave, ~ 4-800 Hz, and the Avantgarde Duo Mezzo seemed good enough at THE Show to make me wonder why people insist on fighting with all this. "

Interesting.

"I would also favor "exponential" horns down to 200 Hz"

Exponential it is then.

"but at LF you enter the World of Mystery, where you will need a Spirit Guide."

From that video it looks like the typical undersized bass (or any undersized) horn could benefit from having an infinite baffle to keep it from going dipole.

"Lastly, I would love it if there were some way to re-use all the "mules" and "stacks" I have built for testing. In fact, I'd settle for perfect recollection of the experiments and the results I got at the time! "

So these are like a bunch of sliced up horn sections you have for molding?

Cheers.
