Jantzen Audio 000-1321 | 0,33 mH | 0,79 Ω | 3% | 24 AWG

The Jantzen Audio 000-1321 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Its 0.33 mH inductance and low 0.79 Ω DC resistance ensure minimal signal loss, making it an excellent choice for high-fidelity audio systems where clarity and detail are paramount.

This coil is ideally suited for use in passive crossover filters, where it helps to accurately divide the audio signal between drivers such as tweeters, midrange units, and woofers. The air core design eliminates core saturation and hysteresis distortion, delivering a pure, uncoloured sound that is especially beneficial in demanding listening environments or high-end DIY speaker projects.

Technically, the coil is wound with 24 AWG wire (0.51 mm diameter) and features a tight ±3% tolerance, guaranteeing consistent performance across production batches. Its compact dimensions of 23 x 8 mm allow for easy integration into crossover boards, while the air core construction ensures stable inductance over a wide frequency range. The 0.79 Ω DC resistance contributes to efficient power handling and minimal thermal drift.

In summary, the Jantzen Audio 000-1321 air core coil offers reliable, low-distortion filtering for discerning audio enthusiasts seeking to optimise their speaker systems with precision components.
