The Intertechnik Silver Coil – 1.30 mH | LU44-AG represents a premium choice for audiophiles and loudspeaker designers who demand uncompromising signal purity. As an air core inductor, it eliminates the core saturation and distortion that can plague iron-based alternatives, ensuring your crossover networks deliver transparent, natural sound reproduction.

This coil is ideally suited for high-fidelity speaker builds, from two-way bookshelf monitors to complex multi-way systems. Its 1.30 mH inductance value makes it particularly effective for midrange and woofer crossover sections, where precise filtering is critical to achieving a seamless driver integration. The ±3.0% tolerance guarantees consistent performance across production batches, essential for matched pairs or production runs.

Technically, the coil is wound with 0.80 mm diameter copper wire, resulting in a DC resistance of just 0.87 Ω. This low resistance minimises power loss and maintains damping factor integrity. The physical dimensions include an outer diameter of 44 mm, a winding width of 23 mm, and a total height of 30 mm, with a central bore of 5.3 mm and a recess diameter of 25.5 mm for secure mounting. The 28 mm core diameter further contributes to stable inductance characteristics.

In summary, the Intertechnik Silver Coil combines meticulous construction with electrical precision, making it a reliable foundation for any serious loudspeaker crossover design.
