Jantzen Audio 000-1939 | 2,7 mH | 0,90 Ω | 3% | 18 AWG

The Jantzen Audio 000-1939 air core coil is a high-quality component designed for audiophiles and speaker builders who demand precision in their crossover networks. This 2.7 mH inductor ensures accurate frequency filtering, helping to deliver a clean and balanced soundstage in your DIY or custom loudspeaker projects. Its robust construction makes it suitable for both home audio systems and professional studio monitors where signal integrity is paramount.

This coil is ideal for use in passive crossover designs, particularly for midrange and woofer applications where reliable inductance values are critical. Whether you are upgrading an existing speaker system or building a new pair from scratch, this component provides the consistency needed to achieve your desired acoustic response. The low DC resistance of 0.90 Ω minimises power loss, ensuring efficient energy transfer and preserving dynamic range.

Technically, the coil features an inductance of 2.7 mH with a tight tolerance of ±3%, guaranteeing predictable performance. It is wound with 18 AWG wire (1.02 mm diameter) on an air core, which eliminates core saturation and distortion, maintaining linearity even at higher power levels. The dimensions are 58 x 20 mm, and it handles a power tolerance of 3 W RMS. This Jantzen Audio coil combines meticulous engineering with durable materials, making it a reliable choice for discerning audio enthusiasts.
