Intertechnik HQ43/2.7/095 | 2,7 mH | 0,33 Ω | 5% | 19 AWG

The Intertechnik HQ43/2.7/095 is a premium 2.7 mH iron core coil designed to deliver precise and reliable crossover filtering in high-fidelity loudspeaker systems. This roller core inductor is an excellent choice for audiophiles and DIY speaker builders seeking to optimise frequency response and achieve clean, accurate sound reproduction. Its robust construction makes it ideal for use in passive crossover networks, particularly in bass and midrange circuits where stable inductance and low losses are critical.

Technically, this coil features a 19 AWG wire diameter of 0.95 mm, ensuring efficient current handling with a low DC resistance of just 0.33 Ω. The inductance tolerance is held to ±5%, guaranteeing consistent performance across production batches. The core measures 43 mm in outer diameter with a 22.5 mm core diameter, a central hole of 4.8 mm, and a total height of 45.5 mm, while the winding width is 30 mm. These specifications make it suitable for compact yet powerful crossover designs. The roller core construction minimises magnetic saturation and distortion, preserving signal integrity even at higher power levels. Whether you are upgrading an existing speaker or building a new set from scratch, this Intertechnik coil provides the accuracy and durability required for professional-grade audio results.
