The Intertechnik LU55/3.90/071 is a precision-engineered 3.9 mH air core coil, designed to deliver exceptional crossover filtering in high-fidelity loudspeaker systems. As an air core inductor, it avoids the core saturation and distortion associated with ferrite or iron-core alternatives, making it an ideal choice for audiophiles and DIY speaker builders who demand transparent, uncoloured sound reproduction. This coil is particularly well-suited for use in passive crossover networks for midrange and tweeter circuits, where maintaining signal purity is critical to achieving a natural and detailed soundstage.

Constructed with 21 AWG wire and a generous 55 mm outer diameter, the LU55/3.90/071 offers a low DC resistance of just 2.01 Ω, minimising power loss and ensuring efficient energy transfer. The ±3% tolerance guarantees consistent performance across production batches, allowing for reliable and repeatable crossover designs. The coil features a 12 mm recess diameter and a 5.3 mm central hole, facilitating straightforward mounting onto crossover boards. With its robust build and meticulous specifications, this Intertechnik air core coil is a dependable component for any serious audio project, delivering the accuracy and sonic transparency required for premium sound systems.
