Continuous Program Power is defined as 3 dB above the Continuous Pink Noise Rating and is 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 600 Hz and 12 kHz 6 For protection against driving below resonant frequency and to keep transformer out of saturation 7 In vertical orientation JBL continually engages in research related to product improvement. Changes introduced into existing products without notice are an expression of that philosophy.
