Jantzen Audio 000-1577 | 0,42 mH | 0,30 Ω | 3% | 18 AWG

The Jantzen Audio 000-1577 air core coil is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. As a premium choice for audio enthusiasts and professional designers, this coil delivers stable, predictable inductance without the risk of core saturation, ensuring pure signal integrity across the frequency range.

This 0.42 mH inductor is ideally suited for use in crossover networks, where precise filtering is critical for accurate driver integration. Whether you are building custom speakers, repairing vintage cabinets, or upgrading existing designs, this coil provides the consistency needed to achieve a balanced, natural soundstage. Its air core construction makes it particularly effective in high-power applications where iron-core alternatives might introduce distortion.

Technically, the coil is wound with 18 AWG wire, resulting in an exceptionally low DC resistance of just 0.30 Ω. This minimises power loss and maintains efficiency, even in demanding systems. The inductance tolerance of ±3% ensures tight adherence to design specifications, while the compact dimensions of 37 x 20 mm allow for flexible placement within enclosures. The air core design eliminates hysteresis and eddy current losses, preserving the transient response and detail of your audio signal.

For discerning builders who refuse to compromise on sound quality, the Jantzen Audio 000-1577 air core coil offers a reliable, high-performance solution that brings clarity and precision to any loudspeaker project.
