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 DN8000 digital electronic
unit was used to provide the necessary cross-
over filters, equalization and time delay. One
watt of power (2.83 volts rms at 250 Hz) was
applied to the midband of the low-frequency
section. The sound-pressure level was nor-
malized for an equivalent one meter distance.
