Jantzen Audio 000-8730 | 3,9 mH | 0,85 Ω | 2% | 16 AWG

The Jantzen Audio 000-8730 wax-coated copper foil coil is a premium component designed for discerning audio enthusiasts and professional loudspeaker builders. This 3.9 mH inductor delivers exceptional performance in high-end crossover networks, ensuring precise frequency filtering for superior sound reproduction. Its construction prioritises signal purity, making it an ideal choice for audiophile-grade speakers, studio monitors, and custom DIY projects where every detail matters.

This coil excels in applications requiring accurate bass management and midrange separation. Whether you are upgrading an existing loudspeaker system or building a new set from scratch, the low 0.85 Ω DC resistance minimises power loss and maintains dynamic headroom. The ±2% tolerance guarantees consistent behaviour across production batches, allowing for reliable crossover design and repeatable results.

Technically, the 16 AWG copper foil winding reduces skin effect and eddy current losses compared to standard round wire, preserving transient response and detail. The wax coating provides mechanical damping and protects against environmental factors, while the compact 113 x 25 mm dimensions facilitate easy mounting. This inductor is a testament to Jantzen Audio’s commitment to quality, offering a perfect balance of low resistance, high inductance accuracy, and robust construction.

For those seeking uncompromising audio performance, this wax coil represents a worthwhile investment in sound quality and long-term reliability.
