Jantzen Audio 000-7691 | 0,38 mH | 0,21 Ω | 2% | 16 AWG

The Jantzen Audio Cross Foil Coil (SKU 000-7691) represents a significant upgrade for any discerning audio enthusiast seeking to refine their loudspeaker crossover network. This 0.38 mH air-core inductor is meticulously engineered from high-purity copper foil, offering a superior alternative to standard wire-wound coils for those who demand the very best from their system.

Ideal for use in high-end passive crossovers, this coil excels in applications where signal purity is paramount. Whether you are designing a new pair of reference loudspeakers or upgrading an existing pair, this component is perfectly suited for tweeter and midrange circuits where its low-loss characteristics can be fully appreciated. Its precise inductance value makes it a reliable choice for achieving accurate frequency division.

Technically, the coil boasts a very low DC resistance of just 0.21 Ω, which minimises signal degradation and ensures efficient power transfer to the drive units. The tight ±2% tolerance guarantees consistent performance from unit to unit, critical for matched stereo pairs. Constructed with 16 AWG equivalent copper foil and measuring 52 x 27 mm, its cross-wound geometry reduces parasitic capacitance and eddy current losses, resulting in a cleaner, more transparent sound.

In summary, this Jantzen Audio foil coil is an investment in audio fidelity, delivering measurable technical benefits that translate into a noticeably more open and detailed listening experience.
