Jantzen Audio 000-1171 | 0,40 mH | 0,598 Ω | 3% | 22 AWG

The Jantzen Audio 0.40 mH air core coil is a precision component designed to elevate the performance of high-fidelity loudspeaker systems. As a crossover inductor, it plays a critical role in dividing the audio signal so that each driver receives only the frequencies it handles best, resulting in a clean, balanced soundstage. This coil is particularly well-suited for audiophile-grade speaker builds, custom crossover networks, and repair or upgrade projects where signal purity is paramount.

Featuring an air core design, this inductor eliminates the core saturation and hysteresis distortion often associated with ferrite or iron-core alternatives, ensuring exceptionally low signal distortion and transparent audio reproduction. With a DC resistance of just 0.598 ohms and a tight tolerance of ±3%, it offers consistent performance and minimal power loss. The coil is wound using 22 AWG wire (0.64 mm diameter) and measures 32 x 8 mm, making it compact enough for integration into a variety of enclosures. Whether you are designing a new pair of speakers or refining an existing setup, this Jantzen Audio air core coil delivers the accuracy and sonic clarity that discerning listeners demand.
