Jantzen Audio 000-2302 | 1,2 mH | 0,33 Ω | 3% | 20 AWG

The Jantzen Audio 000-2302 iron core coil is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. As a trusted name in audio parts, Jantzen Audio delivers this coil to meet the exacting demands of both DIY enthusiasts and professional speaker builders. Its primary role is to serve as a precise inductor within crossover networks, ensuring that frequencies are accurately directed to the appropriate drivers for a clean, balanced soundstage.

This coil is ideally suited for use in passive crossover designs, where it effectively filters low-frequency signals to woofers. Whether you are constructing a new set of bookshelf speakers or upgrading an existing pair, the 1.2 mH inductance value provides reliable and consistent filtering. The robust iron core construction minimises core losses, making it an excellent choice for applications requiring stable performance and controlled bass response.

Technically, the coil features a 1.2 mH inductance with a tight ±3% tolerance, guaranteeing that each unit performs identically for predictable results. It is wound with 20 AWG wire (0.81 mm diameter) and has a low DC resistance of just 0.33 Ω, which helps maintain signal integrity and efficiency. The physical dimensions are 18 x 40 mm, allowing for straightforward integration into most crossover boards. This iron core design offers a high inductance-to-size ratio, making it a practical and sonically transparent solution for discerning audio projects.
