Intertechnik HQ58/1.8/160 | 1,8 mH | 0,08 Ω | 5% | 14 AWG

The Intertechnik HQ58/1.8/160 is a premium 1.8 mH iron core coil designed to elevate the performance of your loudspeaker crossover networks. As part of Intertechnik’s renowned HQ series, this roller core inductor delivers exceptional precision and reliability for audiophile-grade audio projects. Whether you are building custom speakers, upgrading existing designs, or fine-tuning a high-fidelity system, this coil ensures accurate frequency division for cleaner, more natural sound reproduction.

Engineered for demanding use cases, this coil excels in passive crossover circuits where low signal loss and stable inductance are critical. Its robust construction makes it ideal for both two-way and multi-way speaker systems, particularly in applications requiring tight bass control and seamless driver integration. The 1.8 mH value is a common choice for midrange or woofer filtering, offering versatility across a wide range of speaker designs.

Technically, the HQ58/1.8/160 features a 14 AWG wire diameter of 1.6 mm, resulting in an exceptionally low DC resistance of just 0.08 Ω. This minimises power dissipation and preserves amplifier output for dynamic, uncoloured audio. The coil has an outer diameter of 58 mm, a core diameter of 28.8 mm, and a total height of 46.5 mm, with a winding width of 28 mm and a central hole of 4.8 mm. A tight tolerance of ±5% guarantees consistent performance, while the roller core design reduces magnetic saturation for improved linearity.

In summary, this Intertechnik iron core coil combines low resistance, precise inductance, and robust build quality, making it an excellent choice for discerning audio enthusiasts seeking reliable crossover components.
