Thanks Wayne,

So, for a JBL 2370A, they are claiming a cut-off of 630Hz with a depth (length) of ~7". So... 630Hs is a wavelength of 21.6",
so this horn is ~.31 of the wavelength at spec, right? Can I conclude that other horns with similar depths and dimensions
will have similar specs? I realize there's a *lot* of generalization in that statement.

90 x 40 dispersion
Full horn loading to 630 Hz
Dimensions: 6-7/8" H x 17-1/2" W x 6-7/8" D

Thx, Chris
