Jantzen Audio 000-5228 | 3,9 mH | 0,19 Ω | 3% | 15 AWG

The Jantzen Audio 000-5228 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 exceptional performance, making it an ideal choice for high-fidelity loudspeaker systems where accurate frequency filtering is critical. Whether you are constructing custom studio monitors, upgrading existing home theatre speakers, or designing bespoke hi-fi cabinets, this coil ensures that each driver receives only the intended frequency range, resulting in a clean, natural soundstage with minimal distortion.

Technically, this coil features a low DC resistance of just 0.19 Ω, which significantly reduces signal loss and power dissipation, preserving the amplifier’s output for the speakers. The 15 AWG (1.45 mm diameter) winding provides robust current handling, while the ±3% tolerance guarantees consistent performance across production batches. The iron core construction, combined with protective discs, minimises core saturation and eddy currents, maintaining linear inductance over a wide frequency range. With compact dimensions of 55 x 46 mm, it integrates easily into most crossover boards. For discerning listeners seeking to refine their audio systems, this Jantzen Audio coil offers a perfect balance of technical excellence and sonic transparency.
