The Intertechnik LU55/4.70/071 is a premium 4.7 mH air core coil designed for audiophiles and loudspeaker builders who demand precision and clarity in their crossover networks. This high-quality inductor ensures accurate frequency filtering, allowing you to achieve a balanced and transparent soundstage in your DIY speaker projects.

Ideal for use in two-way or multi-way speaker systems, this air core coil excels in low-loss applications where minimal distortion is critical. It is particularly well-suited for midrange and tweeter crossover circuits, where its low DC resistance of 2.21 Ω helps maintain signal integrity and reduce power loss. Whether you are upgrading an existing design or building from scratch, this coil delivers consistent, reliable performance.

Technically, the LU55/4.70/071 features a 21 AWG wire diameter of 0.71 mm, wound on a 55 mm outer diameter former with a 5.3 mm central hole and a 12 mm recess diameter. The coil measures 39 x 25 mm and offers a tight tolerance of ±3%, ensuring each unit performs to specification. As an air core design, it eliminates core saturation and hysteresis effects, providing linear inductance across the audio band.

With its robust construction and precise electrical characteristics, this Intertechnik air core coil is an excellent choice for achieving high-fidelity crossover filtering in your next loudspeaker project.
