Jantzen Audio 000-5122 | 3,0 mH | 0,313 Ω | 3% | 18 AWG

The Jantzen Audio 000-5122 iron core coil with discs is a premium component designed to elevate the performance of high-fidelity loudspeaker systems. As a 3.0 mH inductor with a remarkably low DC resistance of just 0.313 Ω, this coil ensures minimal signal loss and efficient energy transfer within crossover networks. Its robust construction makes it an ideal choice for audiophiles and DIY enthusiasts seeking to refine the sound quality of their speaker builds, particularly in applications requiring precise bass management and frequency division.

This iron core coil excels in passive crossover designs, where it effectively filters low-frequency signals to drive woofers and subwoofers with clarity and authority. The inclusion of protective discs reduces mechanical hum and stabilises the winding, making it suitable for both new speaker projects and upgrades to existing systems. Whether you are crafting a custom two-way monitor or a multi-driver floorstanding speaker, this component delivers consistent, reliable performance.

Technically, the coil features an 18 AWG wire gauge wound on a ferromagnetic iron core, achieving an inductance tolerance of ±3% for accurate crossover slopes. The dimensions of 35 x 45 mm allow for straightforward integration into most enclosures, while the 1.02 mm wire diameter ensures robust current handling. With its low resistance and tight tolerance, this Jantzen Audio coil provides a dependable foundation for achieving transparent, distortion-free sound reproduction in any serious audio project.
