Jantzen Audio 000-1021 | 0,33 mH | 0,48 Ω | 3% | 21 AWG

The Jantzen Audio 000-1021 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. With an inductance of 0.33 mH and a DC resistance of just 0.48 Ω, this coil ensures accurate frequency separation while minimising signal loss, making it an excellent choice for high-fidelity audio systems. Its air core construction eliminates core saturation and hysteresis distortion, delivering clean, transparent sound reproduction.

This coil is ideally suited for use in two-way or three-way speaker designs, particularly for midrange and tweeter filtering where low distortion and precise crossover points are critical. It also performs well in high-end home theatre systems and studio monitor builds, where consistent performance across the audio band is essential.

Technical features include a 21 AWG wire diameter of 0.72 mm, a tight tolerance of ±3% for reliable inductance values, and compact dimensions of 28 x 15 mm, allowing easy integration into tight enclosures. The air core design ensures linearity and low eddy current losses, contributing to a natural, uncoloured sound. Whether you are upgrading an existing design or building from scratch, this Jantzen Audio coil offers the quality and consistency required for serious audio projects.
