Intertechnik E150/180/300 | 1.8 mH | 0.15 Ω | 3% | 9 AWG | Choke Coil

The Intertechnik Air-core Coil with an inductance of 1.80 mH is a premium component designed for audiophiles and loudspeaker builders who demand uncompromising sound quality. Its air-core construction eliminates core saturation and hysteresis distortion, ensuring pure, uncoloured signal transmission in crossover networks. This coil is particularly suited for high-fidelity speaker designs where precise frequency division is critical, such as in two-way or three-way systems for home audio or professional studio monitors. It also excels in passive filter circuits for subwoofers and full-range speakers, where low signal loss and stable performance are paramount.

Technically, this coil features a DC resistance of just 0.15 Ω, minimising power loss and maintaining driver damping factor for tight, controlled bass response. The 3.00 mm copper wire diameter ensures excellent current handling and thermal stability, while the ±3.0% tolerance guarantees consistent performance across production batches. With a total height of 88 mm, it integrates neatly into most crossover layouts. Whether you are upgrading an existing design or building from scratch, this Intertechnik air-core coil delivers the transparency and reliability that discerning listeners value.
