The Intertechnik LU44/039/100 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. With an inductance of 0.39 mH and a tight ±3% tolerance, this coil ensures accurate frequency filtering, allowing you to achieve the exact crossover points required for balanced, natural sound reproduction. Its low 0.33 Ω DC resistance minimises signal loss, preserving the dynamic range and detail of your audio system.

This air core coil is ideally suited for high-fidelity speaker builds, from two-way bookshelf designs to complex multi-way systems. It excels in crossover applications where low distortion and linear performance are critical, making it a reliable choice for both DIY enthusiasts and professional loudspeaker designers. The coil’s non-saturating air core construction eliminates core losses, ensuring stable performance even at higher power levels.

Technical features include a 1 mm wire diameter (18 AWG) wound on a 44 mm outer diameter former, with a 28 mm core diameter and 30 mm total height. The winding width is 23 mm, and the coil features a 5.3 mm central mounting hole with a 25.5 mm recess diameter for secure installation. The ±3% tolerance guarantees consistent inductance values, while the robust construction ensures long-term reliability.

Whether you are upgrading an existing speaker system or building from scratch, this Intertechnik air core coil delivers the precision and sonic transparency demanded by critical listening applications.
