Jantzen Audio 000-5128 | 33 mH | 1,28 Ω | 3% | 18 AWG

The Jantzen Audio 000-5128 iron core coil is a premium-grade component engineered for discerning audio enthusiasts and professional speaker builders. This 33 mH inductor delivers exceptional performance in crossover networks, ensuring precise frequency division for a balanced and transparent soundstage. Its robust construction and tight tolerance make it an ideal choice for high-fidelity loudspeaker designs where accuracy and consistency are paramount.

This coil excels in low-frequency crossover applications, particularly in two-way or three-way speaker systems where reliable bass management is required. It is also well-suited for passive subwoofer filters and impedance compensation networks, providing stable inductance over a wide operating range. The iron core design allows for a compact form factor while maintaining high inductance values, making it a practical solution for space-constrained enclosures without compromising audio quality.

Technically, the coil features a 1.02 mm wire diameter (18 AWG) with a low DC resistance of just 1.28 Ω, minimising signal loss and heat generation. The ±3% tolerance ensures consistent performance across production batches, while the 58 x 46 mm dimensions accommodate easy integration into crossover boards. The iron core is paired with protective discs to reduce eddy currents and mechanical hum, enhancing overall sonic purity.

With its meticulous engineering and reliable construction, this Jantzen Audio coil is a trusted component for achieving accurate, high-resolution sound in custom speaker projects.
