I'm not too sure about using the EV horn with it, it's nothing special. 
Motorola makes a big plastic horn that may or may not be any better. I have
some. Not too bad, but spitty in the upper trebles. Also the horn is long,
so getting an adequate time/phase alignment in a typical application is
unpredictable. They're availiable from Parts Express.

I'm going to tell you about a horn I think is better though. It's a
dynamic constant directivity radial horn that Parts also sells. It's made by
MG, although the catalog may not say so. Also there are bad specs in my
catalog. Efficiency is 99 dB and power is more like 50 watts. It can be used
down to about 1.5 K and is has a smooth curve that rolls off gradually above 
10K. It also costs about $12.

Unfortunately, I doubt such a wide dispersion device would be anay good arrayed
for larger systems. It can work well in vocal PA and monitors with the right 
protection.
