Jantzen Audio 000-5589 | 25 mH | 0,65 Ω | 3% | 15 AWG

The Jantzen Audio 000-5589 iron core coil with discs is a premium component engineered for audiophile-grade loudspeaker crossover networks. Designed to deliver exceptional performance in low-frequency filtering, this 25 mH inductor ensures your system reproduces deep, controlled bass with minimal distortion. Its robust construction makes it an ideal choice for high-end DIY speaker builders and professional audio engineers seeking reliable, long-lasting components for passive crossovers.

This coil excels in applications requiring precise bass management, such as two-way or three-way speaker systems where accurate low-pass filtering is critical. It is particularly suited for use in subwoofer crossovers or as part of a complex multi-driver array, where maintaining signal integrity at lower frequencies is paramount. The included discs facilitate secure mounting, reducing mechanical resonance and ensuring stable operation over time.

Technically, the coil features a 25 mH inductance with a tight ±3% tolerance, guaranteeing consistent performance across production batches. The DC resistance is a low 0.65 Ω, minimising power loss and heat generation. Constructed with 15 AWG wire (1.45 mm diameter) on a ferrite iron core, it offers high saturation current and low core losses. The overall dimensions of 55 x 82 mm make it compact yet powerful, while the ±3% tolerance ensures precise crossover point alignment.

In summary, this Jantzen Audio iron core coil delivers reliable, high-fidelity bass filtering for discerning audio enthusiasts. Its technical precision and build quality make it a worthy investment for any serious loudspeaker project.
