[. . . ] The low-frequency transducers are two 6-inch carbon fiber woofers suitable for difficult climatic environments. The system includes a high-level crossover network that features markedly lower (than conventional) induction values in series with the woofer. We call this innovation LICC (Low Impedance Compensated Crossover).

The two low-frequency transducers shall be cone type loudspeakers having cone diameters of at least 6 inches/152 mm. They shall have voice coils of at least 3 inches/76 mm in diameter and carbon fiber diaphragms. Together they shall present a nominal impedance load of 4 ohms. Sensitivity shall be at least 90 dB when measured at 1 m with an input of 1 watt and the power rating shall be at least 200 watts (AES), 800 watts peak. The high-frequency section shall have a compression driver with a titanium diaphragm of at least 1 inch/25 mm in diameter. It shall present a constant-impedance load of 8 ohms. It shall have a nominal coverage pattern of 100° horizontal by 100° vertical. The system shall be crossed over by an internal, highlevel, passive network having a response of 12 dB/octave. The nominal crossover frequency shall be 2. 5 kHz. The lowpass section of the network shall have minimum inductance in series with the low-frequency drivers. A switch shall be provided to disconnect the crossover network, but not the high-frequency protection circuit, from the drivers to allow bi-amp operation.
