Jantzen Audio 000-1317 | 0,37 mH | 0,62 Ω | 3% | 22 AWG

The Jantzen Audio 0.37 mH air core coil is a high-quality component designed to elevate the performance of your loudspeaker crossover networks. Precision-engineered for audiophile-grade sound reproduction, this inductor ensures clean, accurate signal filtering without the distortion that can arise from core saturation. Whether you are building custom speakers from scratch, upgrading an existing design, or restoring vintage audio equipment, this coil delivers the consistency and transparency required for critical listening environments.

Technically, this air core inductor offers an inductance of 0.37 mH with a tight ±3% tolerance, ensuring reliable and repeatable crossover points. The DC resistance is a low 0.62 Ω, minimising power loss and heat generation within the circuit. Wound with 22 AWG wire (0.64 mm diameter), it provides an excellent balance between current handling and compact form factor. The coil measures 25 mm by 15 mm, making it easy to integrate into most crossover boards. As a true air core design, it avoids the hysteresis and non-linearities associated with ferrite or iron cores, preserving the purity of the audio signal. This Jantzen Audio coil is an ideal choice for discerning enthusiasts seeking measurable performance and sonic accuracy in their loudspeaker projects.
