Jantzen Audio 000-2187 | 0,33 mH | 0,40 Ω | 3% | 24 AWG

The Jantzen Audio 000-2187 iron core coil is a precision-engineered component designed to elevate the performance of your loudspeaker crossover networks. With its robust construction and reliable electrical characteristics, this inductor ensures accurate signal filtering, contributing to a cleaner, more defined audio reproduction in your DIY or professional speaker projects.

This 0.33 mH coil is ideally suited for use in low-pass and band-pass crossover sections, where it effectively manages the frequency distribution between drivers. Whether you are building a new set of bookshelf speakers, upgrading an existing design, or restoring vintage audio equipment, this inductor provides the consistency and sonic transparency required for high-fidelity results. Its iron core construction allows for a compact form factor while maintaining a substantial inductance value, making it a practical choice for space-conscious enclosures.

Technically, the coil features a DC resistance of just 0.40 Ω, minimising power loss and ensuring efficient energy transfer. The winding uses 24 AWG wire with a diameter of 0.51 mm, and the inductance is held to a tight tolerance of ±3% for predictable crossover behaviour. Measuring 16 x 25 mm, this component is built to Jantzen Audio’s exacting standards, offering long-term stability and dependable performance in any audio application.
