Jantzen Audio 000-1443 | 0,87 mH | 0,80 Ω | 3% | 21 AWG

The Jantzen Audio 000-1443 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Manufactured to exacting standards, this 0.87 mH inductor ensures accurate signal filtering, preserving the integrity of your audio reproduction. Its air core construction eliminates core saturation and hysteresis distortion, delivering clean, transparent sound quality that discerning listeners demand.

This coil is ideally suited for use in two-way and three-way speaker systems, where it functions as a low-loss inductor in low-pass or band-pass filter sections. It is particularly effective in high-end DIY speaker projects and professional crossover upgrades, where minimal signal degradation is paramount. The 21 AWG wire gauge offers an excellent balance between current handling and compact form factor, making it suitable for both bookshelf and floor-standing designs.

Technically, the coil features an inductance of 0.87 mH with a tight ±3% tolerance, ensuring consistent performance across production batches. The DC resistance is a low 0.80 Ω, minimising power loss and heat generation. Measuring 33 x 15 mm, the compact air core roll is easy to integrate into crossover boards. The 0.72 mm wire diameter contributes to robust construction, while the air core design guarantees linear behaviour across the audio frequency range.

Whether you are building a new crossover or upgrading an existing one, this Jantzen Audio air core coil delivers reliable, high-fidelity performance that will enhance your listening experience.
