Jantzen Audio 000-2167 | 4,1 mH | 0,82 Ω | 3% | 20 AWG

The Jantzen Audio 000-2167 iron core coil is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. As part of Jantzen’s respected range, this coil delivers reliable and consistent inductive behaviour, making it an essential building block for serious audio enthusiasts and professional designers alike.

This 4.1 mH inductor is ideally suited for use in passive crossover networks, where precise frequency division is critical. It excels in low-pass filter sections for woofers and mid-bass drivers, ensuring a clean transition between drive units. The iron core construction allows for a compact form factor while maintaining high inductance values, making it particularly valuable in designs where space is at a premium without compromising on audio quality.

Technically, the coil offers a DC resistance of just 0.82 Ω, minimising power loss and heat generation within the circuit. The ±3% tolerance ensures accurate and repeatable performance across production batches, which is vital for achieving consistent sound character in both single units and matched pairs. Wound with 20 AWG wire, it strikes an excellent balance between current handling and low resistance. The core measures 37 x 35 mm, providing a robust physical footprint that integrates easily into most crossover boards.

For your next speaker project, this Jantzen Audio iron core coil delivers the precision and reliability needed to realise your design goals with confidence.
