Jantzen Audio 000-7111 | 2,8 mH | 0,34 Ω | 2% | 12 AWG

The Jantzen Audio 000-7111 Cross Foil Coil represents a significant advancement in passive crossover component design, offering audiophiles and loudspeaker builders an exceptional level of performance. This 2.8 mH copper foil inductor is meticulously engineered to deliver the highest possible signal purity, making it an ideal choice for high-end speaker systems where every detail matters.

This coil excels in demanding crossover applications, particularly in premium two-way and three-way loudspeaker designs where precise frequency division is critical. It is perfectly suited for use in studio monitors, high-fidelity home audio systems, and custom loudspeaker projects where minimising distortion and preserving transient response are paramount. The robust construction ensures reliable performance in both new builds and upgrades to existing speaker systems.

Technically, the coil features a 2.8 mH inductance with an exceptionally tight ±2% tolerance, ensuring consistent and accurate crossover behaviour. The 12 AWG equivalent copper foil winding, with a wire diameter of 2.05 mm, provides a very low DC resistance of just 0.34 Ω, minimising power loss and heat generation. The cross foil construction technique reduces eddy current losses and skin effect, resulting in superior high-frequency performance and a more natural, open soundstage. Measuring 97 x 55 mm, this compact yet powerful component integrates seamlessly into most crossover boards.

For the discerning listener seeking the ultimate in crossover componentry, the Jantzen Audio Cross Foil Coil delivers measurable and audible improvements in clarity, imaging, and overall musicality, representing a worthy investment in sound quality.
