Have y'all seen these?
MultiCell Horns For JBL,BEYMA Compression drivers | eBay

For the price I'd be super interested, if they weren't on the other side of the Atlantic

[Altec Best]

Yes the cost of shipping across the pond will likely be more than the actual horns,right now they are $405

He says 300hz horns so I'm thinking 1503's maybe ? I would like to try a pair !

They look nice that's for sure but the point where the waveguide attaches to the multicell is much larger than an Altec and I wonder if the outside cells would be receiving as much input as the more centred ones?

It says there's different throats for 1 inch or 2 inch drivers.

[Altec Best]

I was looking at that too.Where the cells come to form the throat they are supposed to be paper thin.Hard to do if not impossible with MDF !!

There is a fellow in Sweden who made his own from wood. At the throat end of the cells he sanded it down to super thin.

Easily done.

But first you must saturate the wood with cyanoacrylate adhesive(super glue) and let it harden completely, this makes the wood more akin to hard plastic allowing it to be sanded/milled to very thin dimensions with good strength and stability.

It would probably even work with MDF, maybe requiring multiple applications.

Other end of the waveguide.

I like bowtie's idea.

I actually picked this up from a professional wood carver who specialized in birds in natural poses.

A word of caution should go out with the idea. when heated to or near the point of combustion, cyanoacrylate releases cyanide gas. There have been at least a couple cases where carvers using wood burning pencils for detailing have suffered serious health effects from the smoke including at least one case of blindness.

I don't see myself using that anytime soon ! My luck I would be getting my fingers stuck to everything !
