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 'factor-fit' finish.

Designed and built for Eminence, px crossovers feature advanced circuit design to both preserve the crossover and your HF drivers.

A common crossover problem in L-PAD failure brought about by winding burnout when maximum attenuation is prolonged.

Full attenueation 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 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 250Wrms. 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.
