Jantzen Audio 000-1477 | 1,1 mH | 0,92 Ω | 3% | 21 AWG

The Jantzen Audio 000-1477 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Its 1.1 mH inductance and low 0.92 Ω DC resistance ensure accurate signal filtering with minimal power loss, making it an excellent choice for high-fidelity audio systems.

This coil is ideally suited for use in two-way or three-way speaker designs where precise crossover points are critical. It excels in midrange and tweeter circuits, where its air core construction eliminates core saturation and distortion, preserving the natural clarity of the sound. Whether you are building custom speakers or upgrading existing crossovers, this component delivers reliable performance.

Technically, the coil features a 21 AWG wire diameter of 0.72 mm, wound on a 35 x 15 mm former. The ±3% tolerance ensures consistent inductance values across production runs, while the air core design guarantees linear behaviour across the entire frequency range. The low DC resistance contributes to efficient power handling and minimal heat generation.

In summary, this Jantzen Audio air core coil offers a blend of precision, reliability, and sonic purity. It is a trusted choice for discerning audio enthusiasts and professional designers seeking to optimise loudspeaker performance.
