Jantzen Audio 000-0040 | 6,8 mH | 0,78 Ω | 3% | 14 AWG

The Jantzen Audio 000-0040 air core coil is a premium component designed for audiophiles and loudspeaker builders who demand uncompromising sound quality. This 6.8 mH inductor delivers precise crossover filtering, ensuring seamless driver integration and a natural, open soundstage. Its air core construction eliminates core saturation and hysteresis distortion, making it ideal for high-fidelity speaker systems where clarity and detail are paramount.

This coil excels in passive crossover networks for two-way and three-way speaker designs, particularly in midrange and bass applications where accurate inductance values are critical. It is also well-suited for custom audio projects requiring consistent performance across the frequency spectrum. The ±3% tolerance guarantees reliable matching in stereo pairs or multi-driver arrays.

Technically, the coil features a 1.63 mm wire diameter (14 AWG) with a DC resistance of just 0.78 Ω, minimising signal loss and power handling issues. The air core design, wound on a non-magnetic former, ensures linear inductance across varying currents. Measuring 79 x 60 mm, it fits comfortably into most crossover boards. The 6.8 mH value provides effective low-pass filtering for woofers, while the tight tolerance maintains crossover point accuracy.

In summary, this Jantzen Audio air core coil combines precision engineering with audiophile-grade materials, offering a reliable solution for discerning speaker builders seeking transparent, distortion-free performance.
