Jantzen Audio 000-5058 | 15 mH | 1,14 Ω | 3% | 20 AWG

The Jantzen Audio 000-5058 iron core coil is a premium component engineered for high-fidelity loudspeaker crossover networks. Designed to deliver precise and stable inductance, this 15 mH coil ensures accurate frequency filtering, which is essential for achieving a balanced and natural sound reproduction in your speaker builds.

This coil is ideally suited for use in passive crossover designs, particularly for low-pass filters in woofer or subwoofer sections where higher inductance values are required. Its robust construction makes it a reliable choice for both DIY audio enthusiasts and professional loudspeaker manufacturers seeking consistent performance and long-term stability.

Featuring a 20 AWG copper winding with a tolerance of ±3%, the coil offers a low DC resistance of just 1.14 Ω, minimising signal loss and power dissipation. The iron core with discs provides a compact form factor of 45 x 46 mm while maintaining high inductance density. This design reduces stray magnetic fields and ensures linear operation across the intended frequency range.

With its precise specifications and Jantzen Audio’s reputation for quality, this iron core coil is a dependable component for creating accurate and sonically transparent crossover circuits.
