Figure 5 — Distortion
Distortion for the Xcn was measured on
axis in the far field in an anechoic environ-
ment with an input signal that would result
in a sound-pressure level of 115 dB at one
meter. The Klark Teknik DN8000 digital
electronic unit was used to provide the nec-
essary crossover filters, equalization and
time delay. A frequency spectrum typical
of close-miked rock music was employed.
The sound pressure level was normalized
for an equivalent one-meter distance. Plots
of second and third harmonic distortion
are shown referenced to the fundamental.
Figure 4 — Directivity
The directivity index, D
i
, and directivity fac-
tor, R
, of the Xcn were measured with a
full- spherical measurement system as de-
scribed in Figure 1.
Figure 6 — Impedance
The impedance of each frequency band of
the Xcn was measured in an anechoic en-
vironment.
