Jantzen Audio 000-1780 | 4,7 mH | 3,91 Ω | 3% | 24 AWG

The Jantzen Audio 000-1780 air core coil is a premium passive component engineered for high-fidelity loudspeaker crossover networks. Its 4.7 mH inductance, combined with a tight ±3% tolerance, guarantees precise signal filtering and consistent performance across production batches, making it an ideal choice for audiophile-grade speaker builds and custom audio projects.

This coil excels in crossover applications where low distortion and linearity are paramount. It is particularly suited for midrange and woofer filtering in two-way or three-way speaker systems, as well as for use in impedance correction circuits. The air core design eliminates core saturation and hysteresis effects, ensuring clean, uncoloured sound reproduction even at higher power levels.

Constructed with 24 AWG wire (0.51 mm diameter) and a nominal DC resistance of 3.91 Ω, this coil offers a balanced trade-off between low resistive losses and manageable physical size. The compact dimensions of 36 x 15 mm facilitate easy integration into tight enclosures. The ±3% tolerance ensures that each unit meets exacting specifications, critical for maintaining phase coherence and crossover accuracy in matched pairs or production runs.

With its robust build and stable electrical characteristics, the Jantzen Audio 4.7 mH air core coil delivers reliable, high-performance filtering for discerning audio enthusiasts and professional designers alike.
