Super Tweeter Substitution

Hi:

I am in the process of refinishing a pair of Type 4502 Enclosures with LE15A woofers, LE85/H91 horns, and LX13 xovers. I have cobbled up a pair of clone N8000 air core xovers but instead of slotting in the usual 2405/077 I'm thinking outside the box about some Fostex T90A horns. Now I know this may sound like heresy to some of you who bleed JBL blue, but I'm just wondering if anyone has any ideas on the topic???

Thanks

Not so much thoughts, since it's been about 10 years since I looked at the T-90a. In looking at my old MLSSA scans I do however have raw data for one at a meter.

May be for T90A, its dispersion would be too narrow ( in horizontal plane) for higher frequency.
Why not use 2405/077. Especially 077 is very nice 'sounding'
