That's the style of horn mostly associated with
Guigue in France, I think.
He used to make those,
I don't know if he is still in business.

Quite a long window for the CSD. 1.8 seconds. Don't people mostly use something like 3ms?

Is it possible to find somewhere a JIG in order to build this kind of horn ?

Default Horn Mouth

Hi guys ... what would I loose in quality by terminating the Le Cléac'h mouth as it reaches 90 deg instead of rolling back over? May have been covered. I can only turn a 19" horn and would like a lower Fc than 450hz with 2" throat. Thanks, Zene

Most likely you will introduce reflexions back to the throat and directivity pattern will be less smooth.

Thanks jzagaja for the graph. Big difference. Lesson learned. I will not screw up Jeans' work.
