The Intertechnik LU55/039/140 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Its 0.39 mH inductance and exceptionally low 0.18 Ω DC resistance ensure minimal signal loss and accurate filtering, making it ideal for high-fidelity audio systems where clarity and detail are paramount.

This coil is particularly well-suited for use in passive crossover designs for bookshelf speakers, floor-standing towers, and studio monitors. It excels in midrange and tweeter applications where low distortion and linear phase response are critical. The air core construction eliminates core saturation and hysteresis effects, delivering pure, uncoloured sound reproduction even at higher power levels.

Technically, the coil is wound with 1.4 mm diameter wire (15 AWG) on a 28 mm former, with an outer diameter of 55 mm and a total height of 30 mm. The winding width is 23 mm, and the central bore measures 5.3 mm, with a recess diameter of 25.5 mm for secure mounting. The ±3% tolerance ensures consistent performance across production batches, while the 0.18 Ω resistance keeps power dissipation to a minimum.

For discerning audio enthusiasts and professional designers alike, this Intertechnik air core coil offers a reliable, high-performance solution for achieving precise crossover slopes and maintaining signal integrity in demanding loudspeaker projects.
