Jantzen Audio 000-1291 | 0,18 mH | 0,321 Ω | 3% | 21 AWG

The Jantzen Audio 000-1291 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. With an inductance of 0.18 mH and a DC resistance of just 0.321 Ω, this coil ensures minimal signal loss and clean, transparent sound reproduction. Its 21 AWG copper wire winding delivers excellent conductivity, making it an ideal choice for high-fidelity audio systems where clarity and detail are paramount.

This air core coil is perfectly suited for use in two-way or three-way speaker designs, particularly for tweeter and midrange crossover filters. Its low resistance helps maintain the integrity of the audio signal, reducing unwanted coloration and preserving the natural tonal balance of your music. Whether you are building custom loudspeakers or upgrading existing crossovers, this component offers reliable performance for critical listening applications.

Technically, the coil features a ±3% tolerance, ensuring consistent and accurate inductance values across production batches. The air core design eliminates core saturation and hysteresis distortion, providing linear performance across a wide frequency range. With compact dimensions of 30 x 8 mm, it integrates easily into tight enclosures. The 0.72 mm wire diameter further contributes to its low resistance and robust current handling.

In summary, the Jantzen Audio 000-1291 air core coil is a high-quality, reliable component that enhances the precision and sonic purity of any loudspeaker crossover project.
