Jantzen Audio 000-5508 | 33 mH | 2,77 Ω | 3% | 22 AWG

The Jantzen Audio 000-5508 iron core coil is a premium-grade component engineered to deliver precise and reliable low-frequency crossover filtering in high-fidelity loudspeaker systems. With a substantial 33 mH inductance and a low DC resistance of just 2.77 Ω, this coil ensures minimal signal loss and efficient power handling, making it an ideal choice for demanding audio applications.

This iron core coil is particularly well-suited for use in bass and subwoofer crossover networks, where high inductance values are essential for accurate frequency division. It excels in both DIY speaker building projects and professional audio system upgrades, providing clean, controlled bass response without unwanted distortion. The robust construction also makes it suitable for use in passive filters and impedance compensation circuits.

Technically, the coil features a 22 AWG copper wire with a 0.64 mm diameter, wound on a ferromagnetic iron core with protective discs. The ±3% tolerance ensures consistent performance across production batches, while the compact 35 x 45 mm dimensions allow for easy integration into crossover boards. The iron core design maximises inductance per turn, reducing overall coil size and copper losses compared to air-core alternatives.

In summary, the Jantzen Audio 000-5508 iron core coil offers audiophile-grade performance, combining high inductance, low resistance, and precise tolerances for superior low-frequency crossover filtering in any serious speaker system.
