Jantzen Audio 000-1311 | 1,9 mH | 1,26 Ω | 3% | 21 AWG

The Jantzen Audio 000-1311 air core coil is a premium component designed for audiophiles and loudspeaker builders who demand uncompromising signal purity. This 1.9 mH inductor delivers exceptionally low distortion and stable electrical characteristics, making it an ideal choice for high-fidelity crossover networks where even minor signal degradation can compromise sound quality.

This coil excels in passive crossover designs for two-way and three-way speaker systems, particularly in midrange and bass filter sections where precise inductance values are critical. It is also well-suited for custom audio projects, including equalizer circuits and impedance correction networks, where its air core construction eliminates core saturation and hysteresis distortion common in ferrite-based inductors.

Technically, the coil features a 21 AWG (0.72 mm) copper wire winding with a ±3% tolerance, ensuring accurate signal filtering. The DC resistance measures 1.26 Ω, which minimises power loss and heat generation in high-current applications. Its compact dimensions of 40 x 15 mm allow easy integration into tight enclosures, while the air core design guarantees linear performance across the entire audio frequency range. The ±3% tolerance ensures consistent behaviour between units, critical for matched stereo pairs.

For discerning listeners and DIY enthusiasts, this Jantzen Audio air core coil offers a reliable, high-performance solution that preserves the integrity of your audio signal from source to speaker.
