Intertechnik HQ58/5.6/140 | 5,6 mH | 0,22 Ω | 5% | 15 AWG

The Intertechnik HQ58/5.6/140 is a premium 5.6 mH iron core coil engineered for demanding loudspeaker crossover networks. As part of the respected HQ series, this roller core inductor delivers consistent, high-quality performance for audiophile-grade audio systems.

This coil is ideally suited for low-frequency filtering applications, particularly in bass and subwoofer crossover circuits where precise inductance values are critical. It excels in series and parallel configurations within passive crossovers, helping to shape the frequency response with accuracy and minimal signal degradation. Whether you are building custom speakers or upgrading existing designs, this component ensures clean, controlled bass reproduction.

Technically, the coil features a DC resistance of just 0.22 Ω, which minimises power loss and heat generation, preserving amplifier efficiency. The ±5% tolerance guarantees reliable performance within tight specifications, while the 15 AWG wire diameter (1.4 mm) provides robust current handling. With an outer diameter of 58 mm, a core diameter of 28.8 mm, and a total height of 46.5 mm, it offers a compact yet powerful solution. The 4.8 mm centre hole facilitates straightforward mounting.

In summary, the Intertechnik HQ58/5.6/140 is a high-quality, low-resistance iron core coil that delivers precise inductance for superior crossover performance in professional and DIY audio projects.
