Jantzen Audio 000-1893 | 1,8 mH | 0,97 Ω | 3% | 20 AWG

The Jantzen Audio 000-1893 air core coil is a premium component designed for audiophiles and speaker builders who demand uncompromising sound quality. This 1.8 mH inductor delivers transparent, natural signal processing without the core saturation or distortion that can colour the audio path. Its air core construction ensures linear performance across the entire frequency range, making it an ideal choice for high-fidelity crossover networks.

This coil excels in passive crossover designs for two-way and three-way speaker systems, where precise filtering is essential for seamless driver integration. It is particularly well-suited to tweeter and midrange circuits, where low-loss, high-accuracy components make a noticeable difference to imaging and detail retrieval. Whether you are upgrading an existing design or building from scratch, this inductor provides the reliability and consistency required for critical listening applications.

Technically, the coil offers 1.8 mH inductance with a tight ±3% tolerance, ensuring repeatable performance across production batches. The DC resistance is a low 0.97 Ω, minimising power loss and maintaining signal integrity. Wound with 20 AWG (0.81 mm diameter) wire, it handles moderate power levels efficiently. The physical dimensions are 49 mm in diameter and 15 mm in height, allowing for compact integration into most crossover boards. As a true air core design, it avoids the hysteresis and non-linearities associated with ferrite or iron cores.

For discerning builders, this Jantzen Audio coil represents a reliable, high-quality solution for achieving accurate, musical crossover performance.
