Jantzen Audio 000-1439 | 0,59 mH | 0,815 Ω | 3% | 22 AWG

The Jantzen Audio 000-1439 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. This 0.59 mH inductor delivers accurate filtering to ensure clean frequency separation, allowing tweeters, midranges, and woofers to perform at their best. Its low 0.815 Ω DC resistance minimises signal loss, preserving the clarity and detail of your audio.

Ideal for DIY speaker builders and repair technicians, this coil suits both new crossover designs and upgrades to existing systems. It is particularly effective in two-way or three-way speaker configurations where precise bass management and midrange definition are required. The compact 28 x 15 mm dimensions make it easy to integrate into tight enclosures without compromising performance.

Constructed with 22 AWG copper wire wound on an air core, this inductor eliminates core saturation and distortion, ensuring linear behaviour across the audio band. The ±3% tolerance guarantees consistent inductance value, critical for maintaining crossover accuracy. The coil’s robust build and clear labelling simplify installation, while the air core design keeps eddy currents and hysteresis losses to a minimum.

With its reliable construction and precise electrical characteristics, the Jantzen Audio 000-1439 air core coil is a trusted choice for achieving high-fidelity sound in custom speaker projects.
