jcarcopo - definitely better tweets in the di/se's than the standard di's. per what i said, i suspect these are the same as what's in the encores, and i think the moab's, ulfberht's, and the prefect set's also use this same tweeter, tho w/different waveguide.
while it's hard to be certain, imo, the waveguide on the tweets in the di/se's and the encores looks closer to this, than the one you cited:

- just a bit more taper. but, it could be an illusion, as both are listed as the same dimensions on wavecor's site, w/only difference being 4 vs 8 ohms
and i see nothing on the p/e website that looks like the bigger waveguides in the moab's and the ulfberhts. and nothing on wavecor's site w/5 perimeter screws...
it's possible (likely?) that eric can get custom drivers, as he is ordering in quantity. even for a single pair, ha ha!
