Xds Double Subwoofer System Xds Double Subwoofer System Xds Double Subwoofer System Figure 1 — Polar Response The directional response of the Xds was measured in an anechoic environment at a distance of 6.1 m (20 ft.) using 1/3-octave-filtered pink noise with a full spherical measurement system. The polar response of the loudspeaker system at selected 1/3-octave frequencies is shown. The selected frequencies are representative of the polar response of the system.

Xds Double Subwoofer System Figure 2 — Frequency Response The frequency response of the Xds was mea- sured on axis in the far field in an anechoic environment using a swept sine-wave sig- nal. The Klark Teknik DN8000 digital elec- tronic unit was used to provide the neces- sary crossover filters, equalization and time delay. One watt of power (2.00-volts rms at 70 Hz) was applied to the mid band of the low-frequency section. The sound pressure level was normalized for an equivalent one- meter di

Xds Double Subwoofer System 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 harmoni
