Directivity Index and Factor. Horizontal (light) and Vertical (black) Coverage Angles, -6dB point.
All measurements made with PS8TDcontroller.
Response curves : Far Field, Halfspace below 200Hz, anechoic above 200Hz.
Off axis response and polar plot : 1/3 octave averaged anechoic measurements.
Vertical orientations refer to the cabinet in front of house configuration.
Directivity index and factor : computer treatment of polar plots.
Horizontal polar plot (left). 5dB/division.
Upper plot : vertical orientation +25˚.
Center plot : vertical orientation 0˚.
Lower plot : vertical orientation -25˚.
Above : vertical Polar plot. 5dB/division.
