Jantzen Audio 000-2103 | 7,7 mH | 0,94 Ω | 3% | 18 AWG

The Jantzen Audio 000-2103 iron core coil is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. As part of Jantzen Audio’s respected range, this coil delivers the precise inductance and low resistance required for accurate crossover network implementation, ensuring your audio projects achieve their full sonic potential.

This 7.7 mH inductor is ideally suited for use in passive crossover filters, particularly for bass and mid-bass drivers where higher inductance values are necessary. It excels in two-way and three-way speaker designs, providing clean, controlled filtering that helps maintain phase coherence and minimises signal loss. Audiophiles and DIY enthusiasts will appreciate its ability to handle substantial power without saturation, making it a reliable choice for both custom builds and restoration projects.

Technically, the coil features a DC resistance of just 0.94 Ω, which contributes to efficient power transfer and reduced heat generation. The 18 AWG copper wire winding ensures excellent conductivity, while the ±3% tolerance guarantees consistent performance across production batches. The iron core construction allows for a compact form factor—measuring 52 x 35 mm—without compromising inductance stability. This design also helps to minimise external magnetic interference, preserving signal purity.

In summary, the Jantzen Audio 000-2103 iron core coil offers a robust combination of precise electrical characteristics and durable build quality, making it an essential component for serious loudspeaker design.
