Fantastic design, please post pictures when they're done. The profile suggests a figure perhaps

SumacSK: I noticed you have the tweeter located below the fullrange. I read somewhere that this configuration causes the overall radiation axis to be slightly upward as opposed of downward (which is a good thing). Did you noticed this effect?

Hello. My biggest build so far. I got a lovely pair of Coral Flat 8 II and thought a construction called AoE Horns in a Swedish HiFi magazin promising. It was constructed around McFarlow 8" and a tweater both nowaday obsolete. Calculations gave smaller changes. I first tryed with only Corals but didnīt like the upper end and very hard sweet spots. A Sonab tweater and 3īrd degree cut at 8000 (just for try something). The result was awesome. They are now my reference in other builds around BL horns. They should have a better filter because there is a lack in center image around the cut but my mind is still focused on newer projects. Another area of improvement is building with 24 mm ply instead of my 19 mm board since small resonans problems exist.

Kind regards

Looks like you built of some sort of particle board? Just switching to ply of the same thickness would probably be sufficient.

To hot for starting. Couldnīt wait for better material and to stubborn to learn of mistakes. Yes your right that 19 mm ply is sufficient but then probably with stabilisation ribs somewere in mouth. I think a large horn are very sensitive for standing waves across the side panels in that area. When feeling with the hand you notice serious vibrations even on hard board like ply. Harder material is in my schoolbook with higher freqvency but lower amplitude. You know what you have but not what you get. Am i right? Perhapes the mouth isnīt as sensitive for colorization as earlier parts in the horn though.

Thanks for your interest

My attitude is that it is hard to have too much bracing

In the horn pictured above i can see where i'd add at least 4 braces.

is there a reason for the odd mounting orientation of the driver?
