The Intertechnik LU55/047/140 air core coil is a premium-grade component designed for audiophile-grade loudspeaker crossover networks. Its 0.47 mH inductance and 0.19 Ω DC resistance ensure accurate frequency filtering with minimal signal loss, making it ideal for high-fidelity audio systems where clarity and detail are paramount.

This coil excels in passive crossover designs for bookshelf speakers, floor-standing towers, and studio monitors, particularly in midrange and tweeter circuits where low distortion is critical. The air core construction eliminates core saturation and hysteresis effects, delivering linear performance across the entire audio bandwidth. It is also well-suited for custom DIY projects and professional loudspeaker repairs requiring precise crossover points.

Technically, the coil is wound with 1.4 mm diameter wire (15 AWG) on a 55 mm outer diameter former, featuring a 28 mm core diameter and 30 mm total height. The winding width of 23 mm and a 5.3 mm central bore allow for secure mounting. With a ±3% tolerance, this component guarantees consistent electrical characteristics, while the 0.19 Ω DC resistance ensures efficient power handling. The recessed mounting diameter of 25.5 mm simplifies integration into crossover boards.

For discerning audio enthusiasts and engineers, the Intertechnik LU55/047/140 delivers reliable, low-loss performance that enhances the sonic accuracy of any loudspeaker system.
