Intertechnik HQ58/2.7/160 | 2,7 mH | 0,11 Ω | 5% | 14 AWG

The Intertechnik HQ58/2.7/160 is a premium 2.7 mH iron core coil designed to deliver precise and reliable crossover filtering in high-fidelity loudspeaker systems. As part of Intertechnik’s renowned range of roller core coils, this component is engineered for audiophiles and DIY speaker builders who demand consistent performance and minimal signal degradation. Whether you are constructing a new set of bookshelf speakers, upgrading an existing two-way design, or fine-tuning a complex multi-driver system, this coil ensures accurate frequency division for a clean, balanced soundstage.

Technically, the coil features a 14 AWG wire diameter of 1.6 mm, which contributes to its low DC resistance of just 0.11 Ω. This low resistance minimises power loss and heat build-up, allowing the coil to handle higher currents without compromising audio clarity. The 58 mm outer diameter and 28.8 mm core diameter, combined with a winding width of 28 mm and total height of 46.5 mm, provide a robust yet compact footprint suitable for most crossover boards. The central hole of 4.8 mm facilitates easy mounting. With a tolerance of ±5%, each coil guarantees consistent inductance values, ensuring your crossover networks perform as designed. This roller core construction further reduces magnetic saturation and distortion, making it an excellent choice for critical audio applications where purity of sound is paramount.
