Jantzen Audio 000-5223 | 25 mH | 1,92 Ω | 3% | 21 AWG

The Jantzen Audio 000-5223 iron core coil with discs is a premium component designed to elevate the performance of high-fidelity loudspeaker systems. Engineered for precision, this 25 mH inductor ensures accurate crossover filtering, allowing you to achieve seamless driver integration and a balanced, natural soundstage. Its robust construction makes it an ideal choice for both DIY audio enthusiasts and professional speaker builders seeking reliable, long-lasting performance.

This coil excels in demanding crossover networks where consistent inductance and low signal loss are critical. Whether you are designing a two-way bookshelf speaker or a complex multi-driver tower system, the 25 mH value provides the necessary inductive reactance for effective low-pass filtering. The ±3% tolerance guarantees that each unit performs to specification, minimising variations between channels for a cohesive stereo image. With a DC resistance of just 1.92 Ω, it maintains high efficiency and reduces power dissipation, preserving amplifier headroom.

Technical features include a 21 AWG copper winding on a high-permeability iron core, which delivers a compact form factor (45 x 46 mm) without sacrificing inductance. The integrated discs shield the core and minimise stray magnetic fields, reducing interference with nearby components. The ±3% tolerance ensures repeatable results, while the 0.72 mm wire diameter contributes to robust current handling. This coil is a testament to Jantzen Audio’s commitment to quality, offering audiophile-grade performance for discerning listeners.
