Intertechnik E150/220/300 | 2.2 mH | 0.16 Ω | 3% | 9 AWG | Choke Coil

The Intertechnik Air-core inductor, with a value of 2.20 mH, represents a premium choice for audiophiles and loudspeaker designers who demand uncompromising signal purity. This E150 series coil is meticulously engineered to deliver transparent, uncoloured crossover performance, making it an ideal component for high-fidelity speaker systems where every detail matters.

This inductor excels in passive crossover networks for multi-way loudspeakers, particularly in midrange and tweeter circuits where low loss and precise filtering are critical. It is also well-suited for use in high-end audio projects, including studio monitors and bespoke home theatre systems, where maintaining signal integrity directly impacts soundstage and clarity. The robust construction ensures reliable operation in both professional and enthusiast builds.

Technically, the coil features a generous 3.00 mm diameter copper wire, which contributes to an exceptionally low DC resistance of just 0.16 Ω. This minimises power loss and heat generation, preserving amplifier efficiency and driver control. The air-core design eliminates core saturation and hysteresis distortion, ensuring linear performance across the entire frequency range. With a tolerance of ±3.0%, each inductor offers consistent, predictable behaviour for accurate crossover design. The total height of 88 mm allows for flexible placement within enclosures.

For discerning listeners seeking to refine their loudspeaker systems, this Intertechnik air-core inductor provides the technical foundation for a truly transparent and dynamic audio experience.
