Interesting. I'm wondering here if this is the key to eliminating the honkiness I hear in most horn installations. From your experiments, it seems that the low frequency extension is key. Push it too far and it honks. Is that correct?
My guess is that folks often do the math for cutoff frequency and then run the horn too close to that point, or worse, include it in the transition (handoff) to the next driver down. I'm sure everyone here realizes the lower cutoff of a horn is quite abrupt. I'm not sure what function it is, but the slope is steep. That should correspond to some nasty phase shifts. Maybe this is very simple. Push the thing too far and it will honk. Treat it with some respect and don't ask to much, it can sing.
