Jantzen Audio 000-0109 | 0,39 mH | 0,11 Ω | 3% | 13 AWG

The Jantzen Audio 000-0109 air core coil is a premium component designed for audiophiles and loudspeaker builders who demand uncompromising sound quality. This 0.39 mH inductor delivers precise crossover filtering, ensuring clean frequency separation for a natural and transparent audio reproduction. Its air core construction eliminates core saturation and distortion, making it an ideal choice for high-fidelity speaker systems where signal purity is paramount.

This coil excels in a variety of applications, from custom crossover networks in home hi-fi speakers to professional studio monitors and high-end automotive audio installations. Its low DC resistance of just 0.11 Ω minimises power loss and maintains signal integrity, even in demanding designs. Whether you are upgrading an existing system or building from scratch, this component provides the accuracy and reliability required for critical listening environments.

Technically, the coil features a 13 AWG wire diameter of 1.83 mm, wound on a 55 x 30 mm former with a tight tolerance of ±3%. The air core design ensures linear performance across the entire frequency range, with no hysteresis or eddy current losses. This results in consistent, predictable behaviour that simplifies crossover design and optimises driver integration.

With its robust build and precise specifications, the Jantzen Audio 000-0109 air core coil is an essential building block for achieving exceptional sound quality in any serious loudspeaker project.
