Continuos pink noise power ratings are derived from suggested AES standards sending a pink noisesignal having a 6 dB crest factor with a high pass filter set at the specified lower limiting frequency fortwo hours. Continuos program power is a conservative power rating for reproduction of typical audioprogram material.2. Sensitivity measurement is based on pink noise signal with input power of 1 watt and measured at 1meter from the mouth of a horn with a Q of 15 on axis and averaged between 2 and 5 kHz.3. Frequency range is defined as the measured frequency response -10dB relative to the rated sensitivity.801100 1.000 10.000 20.000Frequency (Hz)Frequency response and electrical impedance curve of the compression driver mounted on HF101 horn with inputsignal of 2.83 Volt.150020.0007420 100 1.00010.000 20.000
