Jantzen Audio 000-8379 | 1,28 mH | 0,31 Ω | 2% | 14 AWG

The Jantzen Audio 000-8379 copper foil coil represents a masterful blend of traditional craftsmanship and modern engineering, designed to elevate the performance of high-fidelity loudspeaker systems. This 1.28 mH inductor is meticulously constructed to serve as a critical component in crossover networks, where precision and sonic purity are paramount. Its primary application lies in high-end speaker designs, particularly for audiophile-grade two-way or three-way systems where accurate frequency division is essential for achieving a natural, uncoloured soundstage. The coil’s low DC resistance of just 0.31 Ω ensures minimal signal loss, making it ideal for use in series with bass or midrange drivers where current handling and efficiency are key.

Technically, this component is wound from high-purity copper foil rather than standard wire, which reduces eddy current losses and skin effect distortion, resulting in cleaner signal transmission. The 14 AWG conductor diameter provides an excellent balance between low resistance and manageable physical size. Each coil is precision-wound to a tight tolerance of ±2%, guaranteeing consistent performance across production batches. The wax impregnation process not only stabilises the winding against mechanical vibration—reducing microphonic interference—but also seals the coil against moisture and oxidation. Housed in a compact 82 x 37 mm format, this Jantzen Audio coil is a testament to thoughtful design, delivering the transparency and dynamic accuracy that discerning listeners and loudspeaker builders demand.
