Jantzen Audio 000-7486 | 2,2 mH | 0,42 Ω | 2% | 14 AWG

The Jantzen Audio Cross Foil Coil (SKU: 000-7486) represents a significant advancement in air core inductor design, offering audiophiles and loudspeaker builders a premium component for high-fidelity crossover networks. With an inductance of 2.2 mH and an exceptionally low DC resistance of just 0.42 Ω, this coil is engineered to deliver transparent, uncoloured sound reproduction.

This foil coil is ideally suited for use in high-end passive crossover designs, particularly in the midrange and tweeter sections where signal purity is paramount. Its low-loss construction makes it an excellent choice for critical listening applications, studio monitors, and bespoke loudspeaker projects where every detail matters. The 2% tolerance ensures consistent performance across production runs, allowing for precise crossover alignment.

Technically, the coil features a 14 AWG equivalent copper foil winding with a wire diameter of 1.63 mm, which dramatically reduces eddy current losses compared to conventional round-wire coils. The air core design eliminates core saturation and hysteresis distortion, while the cross foil geometry minimises skin effect and proximity effect. Measuring 88 x 37 mm, this robust component is built to handle demanding audio signals without compromise.

For the discerning enthusiast seeking the ultimate in crossover performance, the Jantzen Audio Cross Foil Coil delivers measurable improvements in clarity, transient response, and overall musicality. It is a worthy investment for any serious loudspeaker project.
