Figure 3 — Beamwidth
The beamwidth of the Xcn, (i.e., the in-
cluded horizontal and vertical coverage
angles at the -6-dB points) was measured
with a full-spherical measurement system
as described in Figure 1.
Figure 2 — Frequency Response
The frequency response of the Xcn was
measured on axis in the far field in an
anechoic environment using a swept sine-
wave signal. The Klark Teknik DN8000 digi-
tal electronic unit was used to provide the
necessary crossover filters, equalization
and time delay. One watt of power (4.00-
volts rms at 500 Hz) was applied to the mid
band of the mid-bass section. The sound-
pressure level was normalized for an
equivalent one meter distance.
