Jantzen Audio 000-0050 | 0,40 mH | 0,14 Ω | 3% | 14 AWG

The Jantzen Audio 000-0050 air core coil is a premium passive component engineered for discerning audio enthusiasts and loudspeaker designers. This 0.40 mH inductor delivers exceptional signal purity, making it an ideal choice for high-fidelity crossover networks where minimal distortion is paramount. Its air core construction eliminates the core saturation and hysteresis effects found in ferrite-based alternatives, ensuring linear performance across the entire audio frequency range.

This coil excels in demanding applications such as two-way and three-way speaker systems, where precise frequency division is critical. It is particularly well-suited for use in high-end home theatre setups, studio monitors, and audiophile-grade loudspeakers. The low 0.14 Ω DC resistance minimises power loss and preserves amplifier damping factor, resulting in tighter bass response and improved transient accuracy.

Constructed with 14 AWG (1.63 mm diameter) copper wire, this inductor offers an excellent balance between low resistance and manageable physical size. The ±3% tolerance ensures consistent performance between units, while the 50 x 25 mm dimensions allow for straightforward integration into crossover boards. As a true air core design, it maintains stable inductance regardless of current levels, guaranteeing predictable filtering behaviour.

Whether upgrading existing speakers or building new designs, this Jantzen Audio coil provides the reliability and sonic transparency required for critical audio applications. Its robust construction and precise specifications make it a trusted component for achieving accurate crossover slopes and natural sound reproduction.
