Final Notes:
Horizontal Dispersion appears fairly close if just a tad more then the rated 80 degrees. Vertical is close to the rated 60 degrees but widens at the lower octaves. Horizontal exhibits a bit of waistbanding just below 2 kHz similar to the B&C ME90 and the Clone ME90 which are somewhat close in size and shape.
Top octave dispersion is determined largely by driver design and throat match-up.
