Jantzen Audio 000-8031 | 0,31 mH | 0,10 Ω | 2% | 12 AWG

The Jantzen Audio 000-8031 copper foil roll represents a significant advancement in passive crossover component design, offering audiophiles and loudspeaker builders an exceptional level of performance. This 0.31 mH air-core inductor is meticulously engineered to deliver precise low-frequency control, making it an ideal choice for high-end loudspeaker crossover networks where accuracy and sonic purity are paramount.

This inductor excels in demanding audio applications, particularly within two-way and three-way speaker systems where maintaining signal integrity is critical. Its air-core construction completely eliminates core saturation and hysteresis distortion, ensuring consistent, linear performance across the entire frequency range. Whether used in a reference-grade home audio system or a professional studio monitor, this component provides the transparency and detail required for accurate sound reproduction.

Technically, the coil features a 12 AWG equivalent high-purity copper foil winding with an exceptionally low DC resistance of just 0.10 Ω, minimising power loss and heat generation. The ±2% tolerance guarantees precise inductance matching between channels, while the compact 61 x 55 mm dimensions allow for flexible integration into crossover layouts. The foil design reduces skin effect and proximity effect distortions, delivering cleaner signal transmission compared to conventional wire-wound inductors.

For the discerning audio enthusiast seeking uncompromising performance, this Jantzen Audio copper foil inductor offers a clear upgrade path to superior sound quality, combining meticulous construction with measurable technical advantages.
