Jantzen Audio 000-7009 | 0,10 mH | 0,05 Ω | 2% | 12 AWG

The Jantzen Audio Cross Foil Coil (SKU: 000-7009) is a premium air-core inductor designed for discerning audio enthusiasts who demand the highest level of performance from their loudspeaker systems. Crafted from high-purity copper foil rather than traditional wire, this component delivers exceptional sonic transparency and minimal signal loss, making it an ideal choice for high-end crossover networks.

This 0.10 mH coil is perfectly suited for use in audiophile-grade speaker designs where precise frequency separation is critical. Whether you are building a new pair of reference monitors or upgrading an existing crossover, the Cross Foil Coil excels in tweeter and midrange circuits, ensuring that each driver receives only the frequencies it is designed to handle. Its air-core construction eliminates core saturation and hysteresis distortion, preserving the integrity of your music.

Technically, this coil features a DC resistance of just 0.05 Ω, ensuring negligible power loss and excellent damping factor. The 12 AWG equivalent foil thickness (2.05 mm) provides high current handling, while the ±2% tolerance guarantees accurate and consistent performance. Measuring 45 x 55 mm, the compact form factor fits neatly into most crossover boards. The foil winding technique reduces skin effect and proximity effect, resulting in a cleaner, more natural soundstage.

For the serious hobbyist or professional designer, the Jantzen Audio 000-7009 Cross Foil Coil represents a significant upgrade over standard wire-wound inductors, offering measurable improvements in clarity and detail.
