Cinema HF Compression Driver PD Series

Description

The POPE Professional PD 2111 high frequency compression drivers are measured sensitivity with a 1m W input on a 25 mm (1 in) terminated tube, averaged from 540 Hz to 2.5 kHz, shall be at least 118 dB SPL. Measuredsensitivity with a 1 W input at a 1 m distance on axis from the mouth of a horn with a Q of 6.3 averaged in the 2 kHz octave band shall be at least 111 dB SPL. As an indication of electromechanical conversion efficiency, the Bl factor shall be at least 18 newtons per ampere. Frequency response, measured on a terminated tube, shall be flat within ± 1 dB from 500 Hz to 3.3 kHz, with 6 dB/octave roll-off above that point. Nominal impedance at 8 ohms and power capacity at 200 watts normal speech or music programme.
