Jantzen Audio 000-5526 | 2,8 mH | 0,18 Ω | 3% | 15 AWG

The Jantzen Audio 000-5526 iron core coil with discs is a premium-grade component designed to elevate the performance of high-fidelity loudspeaker systems. Engineered for precise crossover filtering, this coil ensures that audio signals are accurately divided between drivers, resulting in a clean, natural soundstage with minimal coloration. Its robust construction makes it an ideal choice for both DIY audio enthusiasts and professional speaker builders seeking reliable, long-lasting performance.

This 2.8 mH inductor excels in low-frequency applications, such as bass and mid-bass crossover networks, where its iron core design provides high inductance values in a compact form factor. The inclusion of discs helps to reduce stray magnetic fields, minimising interference with nearby components and preserving signal integrity. Whether you are upgrading an existing design or building a custom loudspeaker from scratch, this coil delivers consistent, repeatable results.

Technically, the coil features a low DC resistance of just 0.18 Ω, which ensures minimal power loss and maintains amplifier damping factor for tight, controlled bass response. The 15 AWG wire diameter (1.45 mm) offers an excellent balance between current handling and low resistance, while the ±3% tolerance guarantees accurate inductance values for precise crossover points. Measuring 47 x 46 mm, the component is compact enough for most enclosures, and the iron core construction provides high saturation levels for dynamic audio peaks.

In summary, the Jantzen Audio 2.8 mH iron core coil with discs is a meticulously engineered component that combines low resistance, precise inductance, and robust build quality. It is an excellent choice for achieving accurate, high-performance crossover networks in demanding audio applications.
