Intertechnik LU78/2.0/140 | 2,0 mH | 0 Ω | 3% | 15 AWG

The LU78/2.0/140 from Intertechnik is a premium 2.0 mH air core coil designed to elevate the performance of your loudspeaker crossover networks. As an air core inductor, it eliminates the risk of core saturation, ensuring pure, distortion-free signal transmission for critical audio applications. This coil is ideal for audiophiles and DIY speaker builders seeking precise frequency filtering in high-fidelity systems, from two-way bookshelf speakers to complex multi-way designs. Its robust construction and tight tolerance make it a reliable choice for both replacement and custom crossover projects.

Technically, this coil features a 15 AWG wire diameter (1.4 mm) wound on a 28 mm core with an outer diameter of 62 mm and a total height of 41 mm. The winding width measures 35 mm, and the coil includes four mounting holes for secure installation. With a ±3% tolerance and a maximum power handling of 80 watts, it delivers consistent, accurate inductance values essential for maintaining crossover slopes and phase coherence. The air core design also minimises eddy current losses, preserving signal integrity across the audio spectrum. Whether you are upgrading an existing system or building from scratch, this Intertechnik coil offers the precision and durability required for exceptional sound reproduction.
