Directivity; Distortion; Impedance - Electro-Voice X-Array XN Brochure & Specs

Xn Three-Way LF/MB/HF System
Figure 4 — Directivity
The directivity index, D , and directivity fac-
i
tor, R , of the Xn were measured with a full-
spherical measurement system as described
in Figure 1.
Figure 5 — Distortion
Distortion for the Xn was measured on axis
in the far field in an anechoic environment
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 necessary cross-
over filters, equalization and time delay. A
frequency spectrum typical of close-miked
rock music was employed. The sound pres-
sure level was normalized for an equivalent
one-meter distance. Plots of second and third
harmonic distortion are shown referenced to
the fundamental.
Figure 6 — Impedance
The impedance of each frequency band of
the Xn was measured in an anechoic envi-
ronment.
