Notes:
1- Maximum Peak SPL: Calculated by adding the loudspeaker’s sensitivity (1W at 1m) to the peak power (dBw) of the amplifier provided.
2- Coverage: Included angle between -6dB points, plus X, minus Y dB, 500 to 3.2k Hz, taken at ISO preferred one-third octave intervals, or for an otherwise specified frequency range.
3- Directivity Index (DI): Difference between on-axis SPL and average SPL (considering all axes) for the specified coverage range. DI= 10 log Q
4- Directivity Factor (Q): Directivity index expressed as a power ratio Q=10 exp DI/10
5- Amplifier Power: The maximum sustained power at less than 1% clipping, averaged over the intended frequency range,
6- Input Sensitivity: The sine-wave input voltage required to reach amplifier clipping, measured within the frequency range used to determine Maximum Peak SPL, with the gain on “normal” and no gain reduction
due to limiting.
7- Input Headroom/Clipping: Maximum input voltage.
8- Input Connector/Impedance: RF shunt capacitance should not reduce impedance by more than 30% at 20k Hz.
9- TBD= to be determined, data not available at time of printing
