PX Professional Crossovers

Designed to work in high-power cabinets, PX Crossovers
are technically superior passive filters available as board-only or complete
with fitted hardware for a smart, economical 'factory-fit' finish.





Designed and built for Eminence by the renowned Winslow Industries,  Px 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, the current is limited when the hf level control is set to '0' on its scale (max. -9dB attenuation). A secondary benefit of the design is to form a voltage divider across the HF driver. The High-Pass Protection uses custom-built aerospace lamps as positive temperature coefficient series varistors. The tungsten filaments effectively track the program material, dynamically maintaining a safe maximum current level to the HF driver without introducing distortion. This circuitry provides smooth 3:1 analog compression during input overload conditions over 250W RMS.
At full drive level approaching clipping, the electrical attenuation to the protected HF driver is -4.5dB. In every way, Eminence Px Crossovers  are a technically superior product.
