Jantzen Audio 000-7706 | 0,43 mH | 0,22 Ω | 2% | 16 AWG

The Jantzen Audio 000-7706 Cross Foil Coil represents a significant upgrade for any discerning audio enthusiast seeking to refine their loudspeaker crossover network. Meticulously engineered from high-purity copper foil, this air core inductor is designed to deliver a level of sonic transparency and precision that standard wire-wound coils simply cannot match.

This 0.43 mH coil is ideally suited for use in high-end crossover designs, particularly in the midrange and tweeter sections where signal purity is paramount. Its low-loss construction ensures that the delicate musical information passing through the filter remains uncoloured, resulting in a more open, detailed, and natural soundstage. Whether you are building a new pair of reference speakers or upgrading an existing design, this component will make a noticeable difference.

Technically, the coil boasts a very low DC resistance of just 0.22 Ω, minimising power loss and ensuring excellent damping factor control over the drive unit. The strict ±2% tolerance guarantees consistent performance between channels, while the 16 AWG equivalent foil conductor offers superior current handling and reduced skin effect distortion compared to round wire. The compact dimensions of 54 x 27 mm allow for flexible placement within the crossover enclosure.

For the serious DIY loudspeaker builder, this Jantzen Audio foil coil is an investment in authentic, high-fidelity sound reproduction.
