The low-frequency transducer shall be a cone type loudspeaker having a cone diameter of at least 12 inches (300mm). Sensitivity shall be at least 99dB when measured at 1m with an input of 1 Watt and have a power rating of at least 250 Watts (AES), 1000 Watts peak. The high-frequency section shall have a compression driver with a diaphragm of at least 1. 75 inches (44mm) in diameter. It shall be connected to a constant directivity horn having a throat diameter of at least 1 inch (25mm) and a nominal coverage pattern of 90° horizontal by 70° vertical. Sensitivity shall be at least 107dB when measured at 1m with an input of 1 Watt and the power rating shall be at least 35 Watts (AES), 140 Watts peak. The system shall be crossed over by an internal, highlevel, passive network having a response of 12dB/octave. The low-pass section of the network shall have minimum inductance in series with the low frequency driver. The high-pass section of the network shall be equalized to optimize the performance of the constant directivity horn. A dynamic high-frequency protection circuit based on a low-value, low-mass filament resistor shall limit the current available to the compression driver.
