ISO This Buschorn, but for a 4" driver
 

This is a second- (or third-?) generation Buschorn model, but for an FE83-sized (3") driver.

Has anyone seen this design adapted for a 4" driver, such as the FE103E, or a 108Sigma?

Thanks in advance,

Here is the page with the pdf.

Yeah, I have seen many versions of that fold. If you look at the fold I posted, it is significantly different, with a more elegant fold and a much bigger flare in the back.

That is the animal I am looking for. Or if anyone ha built the 3" version with an FE83 or FE87, I'd love to know what it reaches in the bass.

Thanks,

A bit after the event, but here's one I found with an enlarged compression chamber a while ago. I suspect it's still for the FE83, but it should be easy enough to enlarge
