The Intertechnik LU44/082/071 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Its non-ferromagnetic construction eliminates core saturation and hysteresis distortion, ensuring pure signal transmission for critical listening applications. This 0.82 mH inductor is ideal for use in high-fidelity two-way or three-way speaker systems where accurate frequency division is paramount, particularly in midrange and tweeter circuits where low distortion is essential.

Technically, the coil is wound with 21 AWG wire, offering a DC resistance of just 0.85 Ω, which minimises power loss and maintains driver damping factor. The ±3% tolerance ensures consistent performance across production batches, vital for matched stereo pairs. With an outer diameter of 44 mm, a recess diameter of 12 mm, and a central hole of 5.3 mm, it integrates neatly into standard crossover boards. The 0.71 mm wire diameter provides an excellent balance between current handling and compact winding.

This air core coil delivers transparent, uncoloured sound reproduction, making it a reliable choice for custom speaker builders and repair technicians seeking to upgrade or restore crossover networks with genuine Intertechnik quality.
