Jantzen Audio 000-7125 | 4,7 mH | 0,47 Ω | 2% | 12 AWG

The Jantzen Audio Cross Foil Coil, SKU 000-7125, represents a significant upgrade for discerning audio enthusiasts seeking to refine their loudspeaker crossover networks. This high-quality copper foil coil is engineered to deliver precise signal filtering, ensuring that each driver in your system receives only the frequencies it is designed to handle. With an inductance of 4.7 mH and a remarkably tight ±2% tolerance, it guarantees accurate and consistent performance, making it an ideal choice for both building new crossover circuits and upgrading existing designs in audiophile-grade speaker systems.

This coil excels in a variety of applications, from high-fidelity home audio setups to professional studio monitors. Its low DC resistance of just 0.47 Ω minimises signal loss and power dissipation, contributing to cleaner, more dynamic sound reproduction. The use of a 12 AWG (2.05 mm diameter) copper foil winding, rather than standard round wire, reduces skin effect and eddy current losses, resulting in improved transient response and detail retrieval. The robust construction, with dimensions of 113 x 55 mm, ensures mechanical stability and consistent electrical characteristics over time.

In closing, the Jantzen Audio Cross Foil Coil is a premium component that brings measurable improvements to any loudspeaker crossover. Its combination of precise inductance, low resistance, and advanced foil winding technology makes it an essential upgrade for those who demand the highest level of audio fidelity from their systems.
