Jantzen Audio 000-1138 | 1,3 mH | 0,82 Ω | 3% | 20 AWG

The Jantzen Audio 000-1138 air core coil is a premium-grade component designed for audiophiles and loudspeaker builders who demand uncompromising signal purity. This 1.3 mH inductor delivers the precise crossover filtering essential for creating coherent, natural-sounding multi-driver speaker systems. Its air core construction eliminates the core saturation and hysteresis distortion found in iron-core alternatives, preserving every nuance of your audio signal.

This coil is ideally suited for high-fidelity loudspeaker crossover networks, particularly in the midrange and tweeter sections where low distortion is critical. It also excels in passive filter applications for studio monitors and high-end home audio systems, where accurate frequency division directly impacts soundstage and imaging. The ±3% tolerance ensures consistent performance across production runs, making it a reliable choice for both DIY enthusiasts and professional designers.

Technically, the coil features a 20 AWG wire diameter with a DC resistance of just 0.82 Ω, minimising power loss and heat generation. Its compact dimensions of 42 x 15 mm allow for easy integration into tight crossover layouts. The air core design guarantees linear behaviour across the entire audio bandwidth, with no audible distortion from core materials. Each unit is wound to exacting standards, ensuring stable inductance over time and temperature.

For your next speaker project, this Jantzen Audio air core coil offers the transparency and precision that separates ordinary designs from truly exceptional sound. Invest in the component that lets your loudspeakers perform at their full potential.
