Jantzen Audio 000-1143 | 0,30 mH | 0,55 Ω | 3% | 22 AWG

The Jantzen Audio 000-1143 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Its non-magnetic construction ensures minimal signal distortion, preserving the purity of your audio signal for a transparent, natural sound reproduction that discerning listeners will appreciate.

This 0.30 mH inductor is ideally suited for use in high-fidelity speaker systems, particularly in crossover filters where accurate frequency separation is critical. Whether you are building custom loudspeakers, repairing vintage cabinets, or upgrading existing designs, this coil delivers consistent performance across a range of applications, from two-way bookshelf speakers to complex multi-driver arrays.

Technically, the coil features a 22 AWG wire diameter of 0.64 mm, with a DC resistance of just 0.55 Ω, ensuring efficient power handling and minimal energy loss. The inductance value of 0.30 mH is held to a tight ±3% tolerance, guaranteeing reliable and repeatable crossover behaviour. Its air core design eliminates core saturation and hysteresis effects, providing linear performance even at higher signal levels. The compact dimensions of 33 x 15 mm make it easy to integrate into tight enclosures.

For your next speaker project, this Jantzen Audio air core coil offers the precision and sonic transparency required to achieve a truly refined listening experience.
