Might that be a little too absorbant a material? ie: over damped, perhaps affecting the response?
I'd like to build a little multi cell out of card or heavy paper that would do tweeter duty. Each cell would be tiny, tho, as the whole thing might be 4-5" wide.

Nothing like a great big pair of speakers to make your day.

I dunno. I did build some 1" throat tractrix horns out of very heay paper mache when I was on Maui. Put the 806 drivers on them. The sounded very good indeed.
But for the top 2 octaves it's a good question.
Depends on how well the horn surfaces are sealed. The structure itself should be so far below a tweeter's operating range that it will be akin to a large, low tuned, tar damped, multi-cell.Originally Posted by Cal Weldon
So the 'name of the game' is to find a material that's either super slick or at least doesn't swell up to cause a micro rough fibrous horn surface when coated with 'whatever' to seal it. FWIW, the thin plastic used to stamp out hotel/motel 'maid service' doorknob hangers is what I've used for tweeter WG experiments, then contact cemented sheet cardboard on the outside to create a well damped, yet rigid enough, constrained layer construction.
Unfortunately, I don't know what type plastic it is or where to get it these days, I special ordered it from a long gone hobby shop as sheet stock of varying thickness for making slot car front/rear air dams.

Dunno, it's somewhat opaque in a 'milky' white sort of way if that helps.

I'll make them out of celluloid!
OK GM, I might have to ask for your help with Hornresp to build a profile. I just don't "get" that software. Wish I could figure it out.
Do they market any thick enough to have any rigidity?
Yeah, it's not very intuitive and not sure I even know about/have tried, all it's capable of, but then when it comes to horn design I usually 'run the numbers' in Excel and just load/sim it in HR, though of course it can't do multi-cells per se.
Regardless, glad to help as much as I can, though may not be real swift to respond due to spending virtually all my quality time these days doing major repairs or recovering from them, so for now only sit at the computer while I'm waiting for the latest round of NSAIDs to kick in.

Sorry to hear that, GM.
