Jantzen Audio 000-0181 | 4,0 mH | 0,83 Ω | 3% | 17 AWG

The Jantzen Audio 4.0 mH Air Core Coil (SKU: 000-0181) is a premium-grade inductor engineered for high-fidelity loudspeaker crossover networks. Its air core design eliminates core saturation and hysteresis distortion, ensuring pure, uncoloured signal transmission for critical audio applications. This coil is ideally suited for use in passive crossover filters for hi-fi speakers, studio monitors, and custom DIY audio projects where precise frequency division and minimal signal degradation are paramount.

Technically, this inductor offers a low DC resistance of just 0.83 Ω, which minimises power loss and maintains excellent damping factor for tight, controlled bass response. The 17 AWG (1.15 mm diameter) copper wire winding provides robust current handling while keeping resistive losses to a minimum. With a tight inductance tolerance of ±3%, it guarantees consistent and accurate crossover performance across production batches. The coil measures 65 x 30 mm, making it compact enough for integration into most speaker enclosures. Jantzen Audio’s meticulous construction ensures reliable, long-term stability, making this air core coil a trusted choice for audiophiles and loudspeaker designers seeking transparent, high-resolution sound reproduction.
