The Intertechnik LU44/027/100 air core coil is a precision component engineered for high-fidelity loudspeaker crossover networks. With an inductance of 0.27 mH and a remarkably low DC resistance of just 0.27 Ω, this coil ensures minimal signal degradation and maintains the integrity of your audio signal. Its ±3% tolerance guarantees consistent performance across production runs, making it an excellent choice for both DIY enthusiasts and professional loudspeaker designers.

This air core coil is ideally suited for use in passive crossover filters, where it can be employed in low-pass, band-pass, or high-pass sections to accurately divide the frequency spectrum between drivers. Its low resistance is particularly beneficial in woofer circuits, where it reduces power loss and preserves amplifier damping factor. The coil's air core construction eliminates core saturation and hysteresis distortion, ensuring linear performance even at high signal levels.

Technically, the coil features a 44 mm outer diameter with a 25.5 mm recess diameter and a 5.3 mm central bore, allowing for secure mounting on standard crossover boards. The winding is executed with 18 AWG wire (1.0 mm diameter), providing an excellent balance between low resistance and manageable physical size. The total height is 30 mm, with a winding width of 23 mm and a core diameter of 28 mm. This robust construction ensures reliable performance in demanding audio applications.

Whether you are building a new speaker system or upgrading an existing design, this Intertechnik air core coil delivers the precision and sonic transparency required for critical listening.
