Figure 2—Frequency Response
The frequency response of the system was
measured on axis in the farfield in an
anechoic environment using a swept sine-
wave signal. The Dx38 digital electronic
unit was used to provide the necessary
crossover filters, equalization and time
delay. One watt of power (2.83 volts rms
at 400 Hz) was applied to the midband of
the low-frequency section. The sound-
pressure level was normalized for an
equivalent one meter distance.
Figure 3—Beamwidth
The beamwidth of the system, (i.e., the in-
cluded horizontal and vertical coverage
angles at the 6-dB-down point) was mea-
sured with a full spherical measurement
system as described in "Polar Response."
