Inexpensive Compression Driver and Horn Combo by Timpano Audio (owned by PRV audio).
The Timpano TPT-DH175 SLIM uses a 1″ phenolic dome compression driver on a shallow 1-3/8"-18 TPI horn which is said to provide a constant 60 x 60 dispersion pattern.
Since this horn is only sold with the included compression driver I only tested the pair, no other drivers tested with this horn.
Test Notes: Off axis and polars measured using the included compression driver. Off axis measurements are smoothed to 1/24 Octave. Since this horn is symmetrical I only measured one axis.
Nominal dispersion appears closer to 70-75 degrees, some waist-banding just below 5k then some narrowing before a strong off axis hot spot in the top octave.
On axis frequency response & distortion.
On axis - measured at 1m (scaled to 2.83v), no smoothing, 4ms gate:
