Jantzen Audio 000-5609 | 15 mH | 0,39 Ω | 3% | 14 AWG

The Jantzen Audio 000-5609 iron core coil with discs is a premium component engineered for audiophile-grade loudspeaker crossover networks. Designed to deliver exceptional performance, this 15 mH inductor ensures precise frequency filtering, enabling your speakers to produce a clean, controlled, and articulate bass response. Its robust construction makes it an ideal choice for both DIY enthusiasts and professional speaker builders seeking to refine low-frequency reproduction.

This coil excels in high-end two-way or three-way crossover designs, particularly where accurate bass management is critical. Whether you are upgrading an existing speaker system or building a custom pair from scratch, the Jantzen Audio iron core coil provides the stability and consistency required for optimal crossover slopes. It is especially well-suited for woofers and subwoofers, where its low DC resistance of just 0.39 Ω minimises signal loss and preserves amplifier damping factor.

Technically, the coil features a 14 AWG copper wire wound on a precision iron core, with a tolerance of ±3% for reliable inductance values. The core is fitted with protective discs, ensuring mechanical stability and reduced vibration. Measuring 55 x 82 mm, it offers a compact footprint without compromising on performance. The iron core design maximises inductance in a smaller package, while the low resistance ensures efficient power handling and minimal heat generation.

In summary, this Jantzen Audio coil is a high-quality solution for achieving accurate, transparent crossover performance, delivering deep, tight bass with exceptional clarity and control.
