Jantzen Audio 000-1090 | 0,12 mH | 0,25 Ω | 3% | 21 AWG

The Jantzen Audio 000-1090 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. With an inductance of 0.12 mH and a DC resistance of just 0.25 Ω, this coil ensures minimal signal loss and accurate filtering, making it an excellent choice for high-fidelity audio systems. Its low-resistance construction is particularly suited for tweeter and midrange circuits where clarity and detail are paramount.

This air core coil is ideal for DIY speaker builders and repair technicians seeking to upgrade or restore crossover networks. It excels in applications requiring precise frequency division, such as two-way or three-way speaker designs, where maintaining phase coherence and reducing distortion is critical. The 21 AWG winding provides a robust yet lightweight solution for compact enclosures.

Technically, the coil features a ±3% tolerance, ensuring consistent performance across production batches. Its air core design eliminates core saturation and hysteresis distortion, delivering linear behaviour across the audio band. Measuring 24 x 15 mm, it fits neatly into most crossover boards. The 0.72 mm wire diameter contributes to its low resistance, while the 0.12 mH inductance offers precise filtering for high-frequency drivers.

In summary, this Jantzen Audio air core coil combines low resistance, tight tolerance, and reliable construction, making it a trusted component for discerning audio enthusiasts.
