Jantzen Audio 000-8690 | 2,3 mH | 0,59 Ω | 2% | 16 AWG

The Jantzen Audio 000-8690 wax-coated copper foil coil represents a significant upgrade for any discerning audio enthusiast seeking to refine their loudspeaker crossover networks. This meticulously engineered component is designed to elevate the performance of high-fidelity speaker systems, delivering a level of sonic purity that standard wire-wound inductors simply cannot match. Its primary application lies within passive crossover circuits, where it ensures precise frequency division between drive units, resulting in a more coherent and transparent soundstage.

Technically, this coil offers a nominal inductance of 2.3 mH with a remarkably tight tolerance of just ±2%, guaranteeing consistent and accurate filtering from unit to unit. The low DC resistance of 0.59 Ω minimises signal loss and power dissipation, preserving amplifier control over the driver. Constructed from 16 AWG copper foil, it benefits from a superior surface-area-to-volume ratio compared to round wire, which reduces skin effect and eddy current distortions for cleaner signal transfer. The generous 94 x 25 mm dimensions house the winding, which is then impregnated with a specialised wax coating. This treatment not only secures the windings against microphonic vibrations but also provides excellent long-term stability and protection. For the dedicated builder aiming for the highest possible performance, this Jantzen Audio coil is an investment in audible clarity and precision.
