Jantzen Audio 000-1804 | 0,025 mH | 0,06 Ω | 1% | 18 AWG

The Jantzen Audio 000-1804 Air Core Coil is a premium-grade component engineered for discerning audio enthusiasts who demand the highest level of signal purity. With an inductance of just 0.025 mH and a DC resistance of only 0.06 Ω, this coil is specifically designed to deliver precise crossover filtering in high-end loudspeaker systems, ensuring that each driver receives only the frequencies it was meant to handle.

This air core coil is ideally suited for use in passive crossover networks for tweeters and midrange drivers, where low inductance and minimal signal degradation are critical. Its construction eliminates the core saturation and hysteresis distortion found in iron-core alternatives, making it a favourite among audiophiles and custom speaker builders seeking transparent, uncoloured sound reproduction.

Technically, the coil features a 1.02 mm diameter 18 AWG copper wire wound on a non-magnetic former, with a tight tolerance of ±1% for consistent performance. The compact dimensions of 31 x 15 mm allow for easy integration into crowded crossover boards, while the 3-watt RMS power handling ensures reliable operation under normal listening conditions. The air core design guarantees stable inductance across the entire frequency range, preserving the integrity of your audio signal from input to output.

Whether you are upgrading an existing system or building a new set of reference speakers, this Jantzen Audio coil offers the precision and sonic transparency that define true high-fidelity engineering.
