Xds Double Subwoofer System

Figure 5 — Distortion

Distortion for the Xds 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.
