The Intertechnik LU44/1.80/071 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Its 1.8 mH inductance and tight ±3% tolerance ensure accurate frequency division, making it ideal for high-fidelity audio systems where sonic transparency is paramount. This coil is particularly well-suited for use in passive crossover designs for bookshelf speakers, floor-standing towers, and custom DIY projects, where low signal degradation is critical.

Constructed with 21 AWG wire and a generous 44 mm outer diameter, the air core design eliminates core saturation and hysteresis distortion, delivering clean, uncoloured sound across the audio spectrum. The DC resistance of just 1.29 Ω minimises power loss, while the 0.71 mm wire diameter ensures robust current handling. Physical dimensions include a 12 mm recess diameter and a 5.3 mm centre hole, facilitating straightforward mounting on crossover boards. The ±3% tolerance guarantees consistent performance between units, essential for matched stereo pairs.

Whether you are upgrading an existing speaker system or building from scratch, this Intertechnik coil provides reliable, low-loss filtering. Its non-magnetic construction and precise specifications make it a trusted choice for discerning audio enthusiasts and professional designers alike.
