Jantzen Audio 000-1279 | 0,25 mH | 0,223 Ω | 3% | 18 AWG

The Jantzen Audio 000-1279 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Its 0.25 mH inductance value makes it particularly well-suited for high-frequency filtering applications, ensuring that only the correct range of frequencies reaches your tweeters or midrange drivers. This level of accuracy is essential for achieving clean, transparent sound reproduction in both home hi-fi systems and professional studio monitors.

Constructed with 18 AWG wire and a generous 1.02 mm conductor diameter, this coil offers a low DC resistance of just 0.223 Ω, minimising signal loss and preserving the dynamic integrity of your audio. The ±3% tolerance guarantees consistent performance across multiple units, which is critical when building matched pairs for stereo systems. As an air core design, it eliminates the core saturation and distortion that can plague iron-core inductors, delivering linear, uncompromised performance even at higher power levels.

Measuring 34 x 15 mm, this compact coil is easy to integrate into your crossover layout. Whether you are designing a new speaker from scratch or upgrading an existing pair, the Jantzen Audio 000-1279 provides the reliability and sonic purity that discerning listeners demand.
