Jantzen Audio 000-7080 | 1,2 mH | 0,21 Ω | 2% | 12 AWG

The Jantzen Audio 000-7080 Cross Foil Coil is a premium-grade air core inductor designed for audiophiles and loudspeaker builders who demand uncompromising crossover performance. Crafted from high-purity copper foil rather than conventional wire, this component represents a significant step up in quality for serious audio projects.

This 1.2 mH coil is ideally suited for use in high-end loudspeaker crossover networks, particularly in the midrange or bass sections where precise frequency filtering is critical. Its low DC resistance of just 0.21 Ω ensures minimal signal loss and power dissipation, making it an excellent choice for both passive and active speaker designs where efficiency and clarity are paramount. The ±2% tolerance guarantees consistent performance across production runs, essential for matched pairs or multi-way systems.

Technically, the coil features a 12 AWG equivalent cross-section from its copper foil winding, which reduces skin effect and eddy current losses compared to standard round wire. The air core construction eliminates core saturation and hysteresis distortion, preserving signal integrity. Measuring 77 x 55 mm, the compact form factor fits neatly into most crossover layouts. Each unit is hand-wound in Denmark to Jantzen Audio’s exacting standards, ensuring reliable, long-lasting performance.

For the discerning listener or designer, this cross foil coil delivers the transparency and accuracy required to realise the full potential of high-quality drive units.
