Jantzen Audio 000-5425 | 3,9 mH | 0,168 Ω | 3% | 14 AWG

The Jantzen Audio 000-5425 iron core coil with discs is a premium component designed for audiophiles and speaker builders who demand precision and reliability in their crossover networks. This 3.9 mH inductor delivers stable inductance, ensuring accurate frequency filtering for a clean, natural sound reproduction. Ideal for use in high-fidelity loudspeaker systems, it excels in both two-way and multi-way designs, providing seamless driver integration and improved phase coherence. Whether you are upgrading an existing pair of speakers or constructing a bespoke set from scratch, this coil is an excellent choice for achieving professional-grade results.

Technically, the coil features a 14 AWG wire diameter of 1.63 mm, which offers an exceptionally low DC resistance of just 0.168 Ω, minimising signal loss and preserving amplifier power. The ±3% tolerance ensures consistent performance across production batches, while the iron core construction with discs reduces eddy currents and hysteresis losses, enhancing linearity. With compact dimensions of 55 x 46 mm, it fits neatly into most crossover layouts. Finished with durable discs for secure mounting, this Jantzen Audio component is built to last, delivering reliable, high-quality filtering for years to come.
