Jantzen Audio 000-7710 | 0,45 mH | 0,22 Ω | 2% | 16 AWG

The Jantzen Audio 000-7710 Cross Foil Coil represents a significant advancement in passive crossover component design, offering audiophiles and loudspeaker builders a premium solution for high-fidelity audio systems. This meticulously engineered copper foil inductor delivers exceptional performance where standard wire-wound coils fall short, making it an ideal choice for critical crossover networks in reference-grade speakers and high-end DIY audio projects.

This coil excels in demanding applications such as two-way and three-way crossover designs, particularly in the midrange and tweeter sections where signal purity is paramount. Its low 0.22 Ω DC resistance ensures minimal power loss and excellent damping factor, while the ±2% tolerance guarantees precise frequency response alignment between drivers. The 0.45 mH inductance value is perfectly suited for creating accurate second-order or third-order filter slopes in audiophile systems.

Technically, the Cross Foil Coil employs a sophisticated construction method using 16 AWG copper foil rather than traditional round wire. This design significantly reduces skin effect and proximity effect distortions, resulting in lower eddy current losses and improved transient response. The coil measures 55 x 27 mm and features a robust air-core design that eliminates core saturation and hysteresis distortion, ensuring linear performance across the entire audio bandwidth. The ±2% tolerance rating provides exceptional consistency for matched pairs or production runs.

For the discerning listener seeking the ultimate in crossover performance, this Jantzen Audio foil coil delivers transparency, detail, and musicality that elevates any loudspeaker design to reference standards.
