Figure 1— Polar Response

The directional response of the system was measured in an anechoic environment at a distance of 6.1m (22 feet) using 1/3-octave-filtered

pink noise with a full spherical measurement system. The Dx34 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

frequencies are representative of the polar response of the system.
