Jantzen Audio 000-2144 | 0,30 mH | 0,13 Ω | 3% | 18 AWG

The Jantzen Audio 000-2144 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 the precision and reliability required for discerning audio enthusiasts and professional designers alike.

This 0.30 mH inductor is ideally suited for crossover networks, where accurate filtering is essential for seamless driver integration. Whether you are building custom speakers or upgrading existing designs, its stable inductance ensures consistent sound character across the frequency spectrum. The iron core construction makes it particularly effective for low-frequency applications, providing a solid foundation for bass reproduction without compromising clarity.

Technically, the coil features a 0.13 Ω DC resistance and is wound with 18 AWG (1.02 mm diameter) wire, balancing low losses with efficient current handling. The ±3% tolerance guarantees tight inductance control, critical for maintaining crossover accuracy. With compact dimensions of 25 x 25 mm, it integrates easily into tight enclosures. The iron core design offers high inductance per turn, reducing the number of windings needed and minimising stray capacitance.

In summary, the Jantzen Audio 000-2144 iron core coil is a reliable choice for achieving precise, repeatable crossover performance in quality speaker builds.
