The Intertechnik LU44/047/100 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. With an inductance of 0.47 mH and a low DC resistance of just 0.36 Ω, this coil ensures minimal signal loss, preserving the clarity and detail of your audio reproduction. Its ±3% tolerance guarantees consistent performance across production runs, making it a reliable choice for both DIY enthusiasts and professional speaker builders.

This air core coil is ideally suited for use in high-fidelity crossover filters, where it helps to accurately divide the audio signal between drivers such as woofers, midranges, and tweeters. Its low resistance makes it particularly effective in series with bass or midrange drivers, where maintaining signal integrity is crucial for tight, controlled sound. The coil’s robust construction also lends itself to custom speaker designs and repair projects where original specifications must be matched precisely.

Technically, the LU44/047/100 features a 44 mm outer diameter and a 28 mm core diameter, wound with 18 AWG wire to achieve its specified inductance and resistance. The total height is 30 mm, with a winding width of 23 mm, and it includes a 5.3 mm central mounting hole for secure installation. The coil’s air core design eliminates core saturation and hysteresis distortion, ensuring linear performance across the entire frequency range.

For discerning audio enthusiasts seeking transparent, accurate crossover performance, this Intertechnik air core coil delivers exceptional value and sonic integrity.
