What happens if...

High Efficiency Speaker Asylum

Need speakers that can rock with just one watt? You found da place.

What happens if you take some midrange horn like my EV SM120A (bi radial with straight lateral sides) and put some "wings" that prolongates the lateral sides in the same angle? Does it effectively lower the cutoff frequency?
I was playing with some thick polystyrene sheets and I heard fuller low midrange when I was putting the "wings".
It made me thinking as my horns are not really able to go down to 400qHz, they're 500Hz horns and 400Hz is pushing it a bit, even tho I'm not the first who does it.
I know Altec was using "wings" on the voice of theater but it was for low frequencies, but I suspect the theory is the same?
But then how to determine the size of the wings?
