Figure 1— Polar Response
The directional response of the system was measured in an anechoic environment at a distance of 6.1 m (22 feet) using 1/3-octave-filtered pink
noise with a full spherical measurement system. The DN8000 digital electronic unit was used to provide the necessary crossover filters,
equalization and time delay. The polar response of the loudspeaker system at selected 1/3-octave frequencies is shown. The selected frequen-
cies are representative of the polar response of the system.
