Jantzen Audio 000-7770 | 0,70 mH | 0,30 Ω | 2% | 16 AWG

The Jantzen Audio 000-7770 Cross Foil Coil is a premium-grade component designed for audiophiles and loudspeaker builders who demand the highest level of crossover performance. This 0.70 mH air core inductor is meticulously engineered to deliver transparent, uncoloured sound reproduction, making it an ideal choice for high-fidelity speaker systems where signal purity is paramount.

This coil excels in crossover networks for both two-way and multi-way loudspeaker designs, particularly in applications requiring precise frequency division with minimal distortion. Its low-resistance construction ensures efficient power handling, making it suitable for use with sensitive tweeters as well as demanding midrange and bass drivers. Whether you are upgrading an existing speaker or building a custom design from scratch, this foil coil provides the accuracy needed for critical listening environments.

Technically, the coil features a 16 AWG copper foil winding with a DC resistance of just 0.30 Ω, ensuring minimal signal loss and excellent current handling. The ±2% tolerance guarantees consistent inductance value, crucial for maintaining crossover point accuracy. Measuring 61 x 27 mm, the air core design eliminates core saturation and hysteresis distortion, while the cross-winding technique reduces parasitic capacitance for cleaner high-frequency performance. Each coil is hand-wound in Denmark to Jantzen Audio’s exacting standards.

For the discerning listener, this foil coil represents a significant upgrade over standard wire-wound inductors, offering improved transient response and a more open, detailed soundstage. Invest in the Jantzen Audio 000-7770 to unlock the full potential of your loudspeaker system.
