Jantzen Audio 000-1377 | 1,87 mH | 0,76 Ω | 3% | 18 AWG

The Jantzen Audio 000-1377 air core coil is a premium component designed for audiophiles and loudspeaker builders who demand uncompromising sound quality. This 1.87 mH inductor ensures accurate crossover filtering, allowing your speaker designs to deliver a clean, natural frequency response without coloration or distortion.

Ideal for use in high-fidelity crossover networks, this coil excels in both two-way and multi-way speaker systems. Whether you are upgrading an existing design or building a custom pair of loudspeakers, its air core construction eliminates core saturation and hysteresis losses, preserving the integrity of your audio signal even at higher power levels. This makes it particularly suitable for tweeter and midrange circuits where precision is paramount.

Technically, the coil features a DC resistance of just 0.76 Ω, minimising power loss and maintaining efficiency. The ±3% tolerance ensures consistent performance across production batches, while the 18 AWG wire (1.02 mm diameter) offers an excellent balance between low resistance and manageable physical size. Measuring 47 x 30 mm, it fits comfortably into most crossover layouts. The air core design also guarantees zero core-induced distortion, resulting in a more transparent and detailed soundstage.

For the discerning listener, this Jantzen Audio air core coil represents a reliable, high-quality choice that will elevate your loudspeaker projects to a professional level.
