Not a drawing, but this shows the shape / my high tech construction.
It's a 74.5mm*74.5mm throat, going to a 400mm*800mm mouth
--> that's about 3" and 16*32" for all y'all in the USA, Myanmar and Liberia
The pictured sides stay more or less flat, the other sides curve. I just took the numbers from Hornresp (a high T Le Cleac'h with a cutoff of 200Hz) and tweaked them slightly:
- oversized the length of the flat sides by 150mm, so it looks a little like a Smith Horn (hoping to extend low frequency support and vertical pattern control)
- oversized the cross sectional area slightly, so I could later fill in the corners to get an octagonal rather than square throat ...which I've now done, but not yet measured.
No impedance plot, I'm not equipped. I'm keen to get a better measuring system sometime. Happy to take recommendations.
