Intertechnik HQ58/8.2/132 | 8,2 mH | 0,30 Ω | 5% | 16 AWG

The Intertechnik HQ58/8.2/132 is a premium 8.2 mH iron core coil engineered for high-performance loudspeaker crossover networks. This roller core inductor delivers exceptional stability and low distortion, making it an ideal choice for audiophile-grade speaker builds where precise frequency filtering is paramount. Whether you are designing a two-way bookshelf system or a complex multi-way floorstanding loudspeaker, this coil ensures accurate bass management and seamless driver integration.

Constructed with a 16 AWG wire diameter of 1.32 mm, the coil achieves a remarkably low DC resistance of just 0.30 Ω, minimising signal loss and preserving amplifier power for cleaner, more dynamic sound reproduction. The generous 58 mm outer diameter and 28.8 mm core diameter provide a robust magnetic circuit, while the 46.5 mm overall height and 28 mm winding width allow for efficient heat dissipation and consistent performance under load. A central mounting hole of 4.8 mm simplifies installation into your crossover board.

With a tight ±5% tolerance, this Intertechnik coil guarantees repeatable results across production batches, ensuring your crossover design performs exactly as intended. The roller core construction further reduces eddy currents and hysteresis losses, delivering a pure, uncoloured audio signal. For discerning DIY enthusiasts and professional designers alike, the HQ58/8.2/132 offers uncompromising quality and reliability for your next loudspeaker project.
