Oliver, many thanks

it gives me an idea of the speaker; maybe somebody has ab better plan to be able to build it.

Does anybody have experience with this speaker?

Olivers drawing is NOT the "Alfredo" horn, but some other design.
I must have the "alfredo"somewhere in my digital library.
I will look again for you.
From memory : they measure 100x55x30 cm.

It may well be one of Edgar's horns from audioXpress (Speaker Builder)

Hi Y'all,

Well, this is where I got it from, but I have not been able to find the website again. Maybe there is more than one Alf Lepp? Maybe he build more than one speaker? :-)

Hello Oliver,

Your design is an Alf Lepp design.
The Alfredo horn is another design.
According to Bert Doppenberg : one of the best for lowther dx3.
I think the design I'm looking for is on my second laptop, is on another place (at school) so I will know tomorrow for sure.
