Jantzen Audio 000-1258 | 5,0 mH | 10,1 Ω | 3% | 29 AWG

The Jantzen Audio 000-1258 air core coil is a premium-grade component designed for audiophiles and loudspeaker builders who demand uncompromising signal purity. This 5.0 mH inductor delivers stable, linear inductance without the risk of core saturation, ensuring your crossover networks perform exactly as intended. Ideal for high-fidelity speaker designs, it excels in low-pass and band-pass filtering applications where consistent performance across the frequency range is critical. Whether you are upgrading an existing system or constructing a bespoke pair of loudspeakers, this coil provides the reliability and sonic transparency required for accurate sound reproduction.

Technically, the coil is wound with 29 AWG wire and features a DC resistance of 10.1 Ω, which helps maintain efficient power handling while minimising insertion loss. The ±3% tolerance ensures precise matching between channels, and the air core construction eliminates hysteresis distortion common in ferrite-based inductors. Measuring 25 x 15 mm, this compact roll fits neatly into most crossover boards. With its robust build and Jantzen Audio’s reputation for quality, this air core coil is a trustworthy choice for achieving refined, natural sound in your next audio project.
