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.
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.
On Axis Frequency Response & Distortion - Tested with PRV DH175Ph-S, D230Ti-S & D280Ti-S
On axis - measured at 1m (scaled to 2.83v), no smoothing, 4ms gate:
