Figure 7 — Wiring Diagram
The wiring diagram of each frequency band
of the Xcb is shown.
Figure 5 — Distortion
Distortion for the Xcb 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. The
sound pressure level was normalized for an
equivalent one-meter distance. Plots of sec-
ond and third harmonic distortion are shown
referenced to the fundamental.

of the Xcb was measured in an anechoic
environment
