Intertechnik LU120/3.0/20 | 3,0 mH | 0,33 Ω | 3% | 12 AWG

The LU120/3.0/20 from Intertechnik is a premium 3.0 mH air core coil designed for audiophiles and loudspeaker builders who demand uncompromising performance. This inductor is engineered to deliver precise crossover filtering, ensuring that each driver in your speaker system receives only the frequencies it was meant to reproduce. Whether you are constructing high-fidelity home audio speakers, studio monitors, or custom sound systems, this coil provides the accuracy and clarity needed for a truly immersive listening experience.

Technically, the coil features a low DC resistance of just 0.33 Ω, which minimises signal loss and allows for efficient power handling, even in demanding applications. The air core design eliminates core saturation and distortion, preserving the purity of the audio signal. With a tolerance of ±3%, you can rely on consistent performance across multiple units. The coil is wound with 12 AWG wire, offering excellent current capacity, and its dimensions—including an outer diameter of 49.5 mm and a total height of 55 mm—make it suitable for a wide range of crossover layouts. The 5.3 mm central hole and 41.5 mm recess diameter facilitate easy mounting.

This air core coil is an ideal choice for discerning builders who value sonic transparency and long-term reliability in their speaker projects.
