1 In half-space (on-wall, 2π).

2 Continuous Pink Noise rating is IEC-shaped pink noise with a 6 dB crest factor. Continuous Program Power is defined as 3 dB above the Continuous Pink Noise Rating

and is a conservative expression of the system’s ability to handle normal speech and music program material.

3 Calculated from sensitivity and power handling, exclusive of power compression.

4 Half-space (on-wall) averaged 100 Hz – 10 kHz, 2.83V.

5 Coverage angle (-6 dB) average between 1.5 kHz and 12 kHz.

6 For protection against driving below resonant frequency and to keep transformer out of saturation.
