Jantzen Audio 000-8650 | 1,3 mH | 0,44 Ω | 2% | 16 AWG

The Jantzen Audio 000-8650 wax-coated copper foil coil represents a significant upgrade for discerning audio enthusiasts seeking to refine their loudspeaker crossover networks. This premium component is engineered to deliver exceptional signal purity, making it an ideal choice for high-fidelity systems where every detail matters. Its construction minimises eddy currents and skin effect, ensuring that the audio signal remains uncoloured and true to the original recording.

This coil is perfectly suited for use in passive crossover designs for bookshelf speakers, floor-standing towers, and studio monitors. The 1.3 mH inductance value is particularly effective for low-pass filtering in two-way or three-way systems, providing a smooth and accurate roll-off. With a ±2% tolerance, it guarantees consistent performance across production batches, which is critical for matched pairs in stereo applications. The low DC resistance of 0.44 Ω further enhances efficiency, reducing power loss and maintaining driver control.

Technically, the coil features a 16 AWG copper foil wound on a non-magnetic former, then coated in a specialised wax compound. This wax treatment dampens mechanical resonances and protects against environmental factors, while the foil geometry reduces proximity effect distortion. Measuring 80 x 25 mm, it integrates easily into most crossover boards. The result is a component that offers both sonic transparency and long-term reliability, elevating any serious audio project.
