Jantzen Audio 000-5240 | 18 mH | 4,07 Ω | 3% | 26 AWG

The Jantzen Audio 000-5240 is a premium iron core coil designed to deliver precise and reliable performance in audio crossover networks. With an inductance of 18 mH and a DC resistance of 4.07 Ω, this component is ideally suited for low-frequency filtering applications, ensuring that bass drivers receive only the intended frequency range for clean, articulate sound reproduction. Its robust construction makes it a preferred choice for audiophiles and DIY speaker builders seeking to upgrade or customise loudspeaker systems.

This coil excels in use cases such as two-way and three-way crossover designs, where accurate bass management is critical. It is particularly effective in high-fidelity home audio systems, studio monitors, and custom speaker projects where minimising signal distortion and maintaining phase coherence are paramount. The iron core construction provides high inductance values in a compact form factor, making it ideal for space-constrained enclosures without compromising performance.

Technically, the coil features a 26 AWG copper winding with a tolerance of ±3%, ensuring consistent inductance across production batches. The iron core is fitted with protective discs, reducing the risk of mechanical damage and stabilising the magnetic field. Measuring 24 x 38 mm, it offers a balanced footprint for easy integration into crossover boards. The low DC resistance of 4.07 Ω minimises power loss, contributing to efficient energy transfer and thermal stability.

In summary, the Jantzen Audio 000-5240 iron core coil combines precise electrical specifications with durable construction, making it a reliable choice for achieving accurate low-frequency filtering in high-quality audio systems.
