Intertechnik HQ58/1.5/160 | 1,5 mH | 0,07 Ω | 5% | 14 AWG

The Intertechnik HQ58/1.5/160 is a premium roller core coil designed to deliver precise and reliable performance in high-fidelity loudspeaker crossover networks. As part of Intertechnik’s renowned range of iron core rolls, this component is engineered to meet the exacting demands of both professional audio designers and dedicated DIY enthusiasts. Its robust construction and carefully specified electrical parameters make it an ideal choice for achieving accurate frequency division in multi-way speaker systems.

This 1.5 mH coil is particularly well-suited for low-pass and band-pass filter sections where controlled inductance and minimal signal loss are critical. With a very low DC resistance of just 0.07 Ω, it ensures efficient power handling and reduces unwanted heat generation, preserving the clarity and dynamics of your audio signal. The ±5% tolerance guarantees consistent performance across production batches, allowing for predictable and repeatable crossover designs.

Technically, the coil features a 14 AWG wire diameter of 1.6 mm, wound on a 58 mm outer diameter core with a 28.8 mm core diameter and a 4.8 mm central hole. The total height is 46.5 mm, with a winding width of 28 mm. These dimensions ensure excellent magnetic properties and mechanical stability, making the HQ58/1.5/160 a dependable choice for high-quality loudspeaker projects where accuracy and low distortion are paramount.
