Intertechnik CO44/8.2/060 | 8,2 mH | 2,27 Ω | 5% | 23 AWG

The Intertechnik CO44/8.2/060 is a precision-engineered 8.2 mH iron core coil, designed to deliver accurate and reliable crossover filtering in high-fidelity loudspeaker systems. As part of Intertechnik’s respected range of iron core rolls, this component is ideal for audiophiles, custom speaker builders, and repair technicians seeking consistent performance in passive crossover networks. Its robust construction and tight specifications make it particularly well-suited for bass and midrange drivers, where stable inductance and low resistance are critical for maintaining sound quality and efficiency.

This coil features a DC resistance of just 2.27 Ω, ensuring minimal signal loss and efficient power handling within your crossover circuit. The inductance value of 8.2 mH is held to a tight ±5% tolerance, guaranteeing predictable filtering behaviour across production batches. Wound with 23 AWG wire (0.6 mm diameter), the coil offers a good balance between current capacity and compact size. Its physical dimensions include an outer diameter of 44 mm, a total height of 28 mm, and a winding width of 23 mm, with a central mounting hole of 5 mm and a recess diameter of 25.5 mm for secure installation. The core diameter measures 28 mm, providing a stable magnetic path for consistent inductance. Whether you are designing a new crossover from scratch or upgrading an existing speaker system, this Intertechnik coil delivers the precision and durability required for professional-grade audio results.
