Jantzen Audio 000-2256 | 4,7 mH | 1,75 Ω | 3% | 24 AWG

The Jantzen Audio 000-2256 iron core coil is a high-quality component designed to elevate the performance of your loudspeaker crossover networks. Precision-engineered for audiophile-grade sound reproduction, this coil ensures accurate signal filtering, allowing each driver in your speaker system to operate within its optimal frequency range. Whether you are building custom speakers from scratch or upgrading an existing design, this component delivers reliable and consistent results.

This coil is ideally suited for use in passive crossover circuits, particularly for low-pass filtering in woofers and subwoofers. Its robust iron core construction provides high inductance values in a compact form factor, making it an excellent choice for projects where space is at a premium. Hobbyists and professional audio engineers alike will appreciate its ability to handle moderate power levels while maintaining signal integrity.

Technically, the coil offers a nominal inductance of 4.7 mH with a tight ±3% tolerance, ensuring predictable and repeatable performance. The DC resistance is a low 1.75 Ω, minimising power loss and heat generation. Wound with 24 AWG wire (0.51 mm diameter), it strikes a fine balance between current handling and compact size. The physical dimensions are 21 x 30 mm, and the coil features a varnished iron core for reduced eddy currents and improved linearity.

In summary, the Jantzen Audio 4.7 mH iron core coil is a dependable choice for achieving precise crossover slopes and enhancing the overall clarity of your loudspeaker system. Its meticulous construction and tight tolerances make it a worthy addition to any serious audio project.
