Electro-Voice XI-2181, 2181F manual Xi-2181, Distortion

Xi-2181 Bass System

	Figure 5 — Distortion
	Distortion for the Xi was measured on axis
	in the far field in an anechoic environment
System	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
Bass	an equivalent one-meter distance. Plots of
	second and third harmonic distortion are
Xi-2181	shown referenced to the fundamental.

Figure 6 — Impedance

The impedance of each frequency band of the Xi was measured in an anechoic environment
