Jantzen Audio 000-7940 | 4,0 mH | 0,83 Ω | 2% | 16 AWG

The Jantzen Audio 000-7940 Cross Foil Coil represents a significant upgrade for any serious loudspeaker project, delivering the kind of precision and clarity that discerning listeners demand. This 4.0 mH copper foil inductor is engineered to elevate crossover networks, ensuring that each driver receives exactly the right frequency range for a cohesive and natural soundstage. Whether you are building a pair of high-end floorstanding speakers, refining a studio monitor, or restoring a classic audiophile system, this coil provides the accuracy needed to achieve a truly transparent performance.

At the heart of this component lies a meticulously wound copper foil design, which offers lower eddy current losses and superior current handling compared to standard wire-wound coils. With a DC resistance of just 0.83 Ω and a generous 16 AWG equivalent conductor thickness, it maintains signal integrity even under demanding conditions. The ±2% tolerance guarantees consistent behaviour across the frequency spectrum, while the compact 96 x 27 mm form factor allows for flexible placement within your crossover layout. Every detail, from the robust construction to the precise inductance value, reflects Jantzen Audio’s commitment to uncompromising quality. For the enthusiast seeking the last word in sonic refinement, this foil coil is an investment that pays dividends in every listening session.
