Jantzen Audio 000-5387 | 10 mH | 0,39 Ω | 3% | 15 AWG

The Jantzen Audio 000-5387 iron core coil with disks delivers exceptional performance for demanding loudspeaker crossover networks. Designed for audiophiles and custom speaker builders, this component ensures accurate frequency division, allowing tweeters, midrange drivers, and woofers to work in perfect harmony. Its robust construction makes it ideal for high-end two-way or three-way speaker systems, where precise filtering is critical to achieving a natural, uncoloured soundstage.

Technically, this coil offers a 10 mH inductance with a tight ±3% tolerance, ensuring consistent and reliable crossover behaviour. The low DC resistance of just 0.39 Ω minimises signal loss and power dissipation, preserving amplifier efficiency and dynamic range. Wound with 15 AWG (1.45 mm diameter) wire, it handles up to 4 watts RMS continuously without saturation. The iron core design provides high inductance in a compact form factor, while the integrated disks reduce eddy currents and stabilise the magnetic field. Measuring 63 x 56 mm, it fits neatly into most crossover boards. Whether upgrading an existing design or building from scratch, this Jantzen Audio coil offers the precision and sonic transparency that serious listeners demand.
