Jantzen Audio 000-2157 | 0,70 mH | 0,194 Ω | 3% | 18 AWG

The Jantzen Audio 000-2157 iron core coil is a meticulously engineered component designed to elevate the performance of high-fidelity speaker systems. This 0.70 mH inductor delivers precise crossover filtering, ensuring that each driver in your loudspeaker receives only the frequencies it was intended to handle, resulting in a clean, accurate, and immersive soundstage.

Ideal for audiophiles and custom speaker builders, this coil excels in passive crossover networks where reliable frequency division is paramount. Whether you are upgrading an existing pair of speakers or constructing a new set from scratch, this component provides the consistency and sonic transparency required for critical listening applications. Its robust construction makes it suitable for both home hi-fi and professional audio installations.

Technically, the coil features a 0.194 Ω DC resistance, minimising signal loss and maintaining efficiency within the circuit. The ±3% tolerance ensures tight adherence to the specified inductance value, crucial for predictable crossover behaviour. Wound with 18 AWG wire (1.02 mm diameter) around a ferromagnetic iron core, it achieves the desired inductance in a compact 29 x 35 mm footprint. The iron core design offers high saturation levels and low core losses, making it an excellent choice for low-frequency filtering where larger air-core coils would be impractical.

In summary, the Jantzen Audio 000-2157 iron core coil combines precise electrical specifications with durable construction, offering a reliable solution for achieving superior sound quality in any high-performance speaker system.
