Jantzen Audio 000-1548 | 0,40 mH | 0,183 Ω | 3% | 15 AWG

The Jantzen Audio 000-1548 air core coil is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. As a premium crossover element, this 0.40 mH inductor ensures precise signal filtering, allowing for seamless driver integration and a remarkably natural soundstage. Its air core construction eliminates core saturation and hysteresis distortion, preserving the purity of the audio signal across the entire frequency range.

This coil is ideally suited for audiophile-grade speaker builds, studio monitor crossovers, and custom DIY audio projects where accuracy and transparency are paramount. Whether you are designing a two-way bookshelf speaker or a complex multi-driver system, this inductor provides the reliable, low-loss performance required for critical listening environments.

Technically, the coil features a 15 AWG wire diameter (1.45 mm) with a very low DC resistance of just 0.183 Ω, minimising power loss and ensuring efficient energy transfer. The inductance value of 0.40 mH is held to a tight ±3% tolerance, guaranteeing consistent performance across production batches. The compact dimensions of 45 x 25 mm facilitate easy integration into crossover boards, while the robust air core design remains stable under varying power levels.

For discerning audio enthusiasts and professionals, this Jantzen Audio air core coil represents a reliable investment in sonic accuracy, delivering transparent crossover behaviour that lets your loudspeaker designs truly shine.
