Jantzen Audio 000-0133 | 2,5 mH | 0,368 Ω | 3% | 13 AWG

The Jantzen Audio 000-0133 air core coil is a premium component designed for discerning audio enthusiasts and professional speaker builders who demand uncompromising sound quality. This 2.5 mH inductor delivers exceptional performance in crossover networks, ensuring precise frequency filtering that preserves the integrity of your audio signal. Its air core construction eliminates core saturation and hysteresis distortion, making it an ideal choice for high-fidelity loudspeaker designs where clarity and transparency are paramount.

This coil excels in a variety of applications, from custom-built home theatre systems to studio monitors and high-end two-way or three-way speaker configurations. It is particularly well-suited for crossover networks in audiophile-grade designs, where low signal distortion and accurate phase response are critical. Whether you are upgrading an existing speaker system or constructing a new pair from scratch, this component provides the reliability and sonic purity required for reference-level performance.

Technically, the coil features a 2.5 mH inductance with a tight ±3% tolerance, wound using 13 AWG wire (1.83 mm diameter) to minimise resistance, which is measured at just 0.368 Ω. The air core design ensures linear behaviour across a wide frequency range, while the compact dimensions of 72 x 60 mm allow for flexible integration into crossover boards. This combination of low DC resistance and precise inductance makes it an excellent choice for maintaining signal integrity in demanding audio applications.

In summary, the Jantzen Audio 000-0133 air core coil offers a perfect balance of technical precision and sonic performance, making it a reliable foundation for any high-quality loudspeaker crossover.
