Additional Notes:
Small 60x60 1-3/8"-18 TPI horn flare by PRV Audio Brazil.
This horn is also used in the WG230Ti (with D230Ti-S driver) and WG175Ph (with DH175Ph-S driver), each of those drivers have been tested below along with a test of the D280Ti-S.

Test Notes: Off axis and polars measured using the PRV D230Ti-S (making this the same as the WG230Ti combo). Off axis measurements are smoothed to 1/24 Octave. Since this horn is symmetrical I only measured one axis.
Polar Sonogram truncated at 17kHz to prevent the small off axis peak near 20k from skewing the 0dB point and contour lines.
Notes:
Nominal dispersion does appear to match the stated 60 degree coverage angle, but only above about 5k. Below the pattern slowly widens to around 100 -110 degrees a little above 2k below which any pattern control is lost.
