Jantzen Audio 000-5072 | 1,4 mH | 0,12 Ω | 3% | 15 AWG

The Jantzen Audio 000-5072 iron core coil with discs is a premium component designed to elevate the performance of high-fidelity loudspeaker systems. This 1.4 mH inductor delivers precise low-frequency crossover filtering, ensuring that your speaker designs achieve clean, accurate bass reproduction without unwanted distortion. Its robust construction makes it ideal for both DIY audio enthusiasts and professional loudspeaker manufacturers seeking reliable, long-lasting components.

This coil excels in crossover networks where tight control over the low-end response is critical. Whether you are building a two-way bookshelf speaker or a multi-driver floorstanding system, the 1.4 mH inductance value allows for seamless integration with woofers and subwoofers. The ±3% tolerance guarantees consistency across production runs, making it suitable for matched pairs or multi-speaker arrays where phase coherence matters.

Technically, the coil features a 15 AWG wire diameter (1.45 mm) and an exceptionally low DC resistance of 0.12 Ω, minimising power loss and heat buildup. The iron core design with attached discs enhances magnetic flux concentration while reducing stray fields, resulting in higher inductance per turn and improved linearity. Measuring 45 x 46 mm, this compact component fits easily into most crossover layouts. Jantzen Audio’s meticulous winding process ensures stable performance over time, making this coil a trusted choice for critical audio applications.
