Best large format horns for home use

FWIW: Altec 288-8G - Electro Voice HR60 HELP

So if I understand correctly, the EV horns have a slightly smaller throat? Is it just the HR60, or the HR90 and HR120 also?

I have a pair of what looks like these,


someone gave them to me. if they can do you any good and you can use them.

Those look pretty nice! Have you tried any of your large fomat drivers on them?

According to some quick research those horns have a 1.3" throat. Any way to make them larger to match the 1.4" Altec drivers?
