Jantzen Audio 000-1841 | 0,40 mH | 0,33 Ω | 3% | 18 AWG

The Jantzen Audio 000-1841 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. With an inductance of 0.40 mH and a DC resistance of just 0.33 Ω, this coil ensures minimal signal loss and accurate frequency filtering, making it an excellent choice for high-fidelity audio systems. Its air core construction eliminates the risk of core saturation, preserving signal purity even at higher power levels.

This coil is ideally suited for use in two-way or three-way speaker designs, where it can be employed for low-pass or band-pass filtering of midrange and tweeter drivers. The ±3% tolerance guarantees consistent performance across production batches, which is essential for matched stereo pairs or multi-driver arrays. Hobbyists and professional designers alike will appreciate its reliability in both new builds and crossover upgrades.

Constructed with 18 AWG wire and a 1.02 mm conductor diameter, the coil offers a good balance between low resistance and manageable physical size. Its dimensions of 37 x 30 mm allow for straightforward mounting on crossover boards. The air core design, combined with tight tolerance winding, ensures stable electrical characteristics over time, contributing to predictable and repeatable acoustic results.

For any loudspeaker project demanding transparent and accurate crossover behaviour, this Jantzen Audio air core coil delivers the technical foundation required for superior sound reproduction.
