Jantzen Audio 000-5454 | 12 mH | 0,67 Ω | 3% | 18 AWG

The Jantzen Audio 000-5454 iron core coil is a premium component engineered for audiophile-grade speaker crossover networks. Designed to deliver a controlled and articulate low-frequency response, this 12 mH inductor ensures that bass reproduction remains tight, punchy, and free from unwanted distortion. Whether you are building custom loudspeakers, upgrading existing designs, or restoring vintage audio equipment, this coil provides the reliability and sonic accuracy demanded by discerning listeners and professional designers alike.

Constructed with a 1.02 mm diameter (18 AWG) copper wire wound around a precision iron core, this coil offers a low DC resistance of just 0.67 Ω, minimising signal loss and preserving amplifier power. The ±3% tolerance guarantees consistent inductance value across production runs, essential for maintaining crossover point accuracy. Measuring 55 x 46 mm, the compact form factor is complemented by integrated discs that reduce stray magnetic fields and mechanical hum. The iron core construction allows for high inductance in a relatively small package, making it ideal for low-pass filter sections where space is at a premium. With its robust build and meticulous quality control, this Jantzen Audio coil is a trustworthy choice for achieving precise, natural-sounding bass in any high-fidelity loudspeaker project.
