Would these work for an Optimus 990 replacement?
I blew a tweeter in one of my 990s a few years ago and have been searching for either a tweeter to fit in the original horn (haven't been able to find one) or replace the horn and tweeter. Anyone know if this will fit in the cut out?
The size of the hole required for this to fit in the enclosure is 13-5/8" x 3-3/4".

What is the horizontal/vertical dispersion of this horn?
Most PA cabinet horns are 40 x 90. There are other tighter configurations for special applications which might be used in an array(with overlapping patterns) but these are not nearly as common especially from an entry level or hobby application.
