Eminence px cabinet-ready crossovers feature advanced circuit design to both preserve the crossover and your HF drivers. A common crossover problem is L-pad failure brought about by winding burnout when maximum attenuation is prolonged. Full attenuation concentrates the maximum voltage drop in a small winding area - a potentially damaging state even with high-power L-pad devices. In px crossovers, current is limited when the high frequency level control is set to '0' on its scale (±9 dB attenuation). A secondary benefit of the design is to form a voltage divider across the high frequency driver. The high-pass protection uses custom-built aerospace lamps. The tungsten filaments effectively track the program material, dynamically maintaining a safe maximum current level to the high frequency driver without introducing distortion. This circuitry provides smooth 3:1 analog compression during input overload conditions over 250 watts RMS. At full drive level approaching clipping, the electrical attenuation to the protected high frequency driver is -4.5 dB. In every way, Eminence px crossovers are a technically superior product. For use with 8 ohm drivers.
