Figure 5 — Distortion
Distortion for the Xi 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 sound pressure level was normalized for
an equivalent one-meter distance. Plots of
second and third harmonic distortion are
shown referenced to the fundamental.
