PS8+LS400 : THD for 110dBSPL @ 1m.
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.
