Intertechnik CO44/150/050 | 15 mH | 4,4 Ω | 5% | 24 AWG

The Intertechnik CO44/150/050 is a meticulously engineered 15 mH iron core coil, designed to deliver precise and reliable performance in high-fidelity loudspeaker crossover networks. As part of Intertechnik’s respected range of tube core coils, this component is ideal for audiophiles and DIY speaker builders seeking to refine low-frequency filtering with minimal signal degradation. Its robust construction ensures stable inductance, making it a trusted choice for both custom crossover designs and replacement applications in existing speaker systems.

This coil excels in low-pass filter sections, where its iron core provides high inductance values in a compact form factor. It is particularly well-suited for woofer and subwoofer crossover circuits, enabling accurate frequency division while maintaining low distortion. The 4.4 Ω DC resistance and ±5% tolerance ensure consistent performance, allowing for precise tuning of crossover points. Whether used in two-way or multi-way speaker designs, this coil helps achieve a clean, natural sound reproduction.

Technical features include a 24 AWG wire diameter, a 44 mm outer diameter, and a 28 mm core diameter, with a total height of 28 mm and a winding width of 23 mm. The recess diameter measures 25.5 mm, and the central hole is 5 mm, facilitating straightforward mounting. The tube core design minimises eddy currents and hysteresis losses, contributing to low signal distortion and stable inductance across the operating frequency range.

In summary, the Intertechnik CO44/150/050 iron core coil offers a reliable solution for achieving accurate low-frequency filtering in high-quality audio systems, combining robust construction with precise electrical specifications.
