Jantzen Audio 000-7721 | 0,49 mH | 0,24 Ω | 2% | 16 AWG

The Jantzen Audio 000-7721 Cross Foil Coil is a premium-grade copper foil inductor designed for discerning audio enthusiasts who demand the highest level of crossover performance. With an inductance of 0.49 mH and an exceptionally low DC resistance of just 0.24 Ω, this air core coil ensures minimal signal loss and superior transient response, making it an ideal choice for high-fidelity loudspeaker systems.

This coil is perfectly suited for use in passive crossover networks, particularly in tweeter and midrange circuits where precision and clarity are paramount. Its low-resistance construction also makes it an excellent option for audiophile-grade speaker upgrades or custom DIY projects, where every detail of the sound signature matters.

Technically, the coil features a 16 AWG equivalent copper foil winding, which reduces skin effect and eddy current losses compared to standard round wire designs. The ±2% tolerance guarantees accurate inductance matching, while the compact dimensions of 55 x 27 mm allow for easy integration into tight enclosures. The air core design eliminates core saturation and hysteresis distortion, ensuring pure, uncoloured sound reproduction.

In summary, the Jantzen Audio 000-7721 Cross Foil Coil delivers exceptional build quality and electrical performance, making it a reliable choice for achieving precise, transparent crossover behaviour in any high-end audio system.
