Vera Audio midbass horn

Presenting some measurements of our prototype midbass horn.

Please take note of the following before looking at the measurements:
-The directivity measurements were conducted with a JBL 2220 driver that had resonance and dip around 700 Hz area
- No EQ was applied to the measurements, these are raw
- The horn was measured in a small gym. Measurements are therefore not anechoic, and below 150-200 Hz area the directivity measurements cannot be trusted

On axis measurement with JBL 2220 (resonance/dip arround 700 Hz - driver fault!). No EQ applied.

Vertical measurements above reflective floor at different heights with JBL 2220. No EQ applied.

Same as previous, but showing only 70 Hz to 700 Hz and fewer graphs with bigger increments/lower resolution.
