Intertechnik HQR32/1.5/71 | 1,5 mH | 0,69 Ω | 5% | 21 AWG

The Intertechnik HQR32/1.5/71 is a precision-engineered tube core coil designed to deliver accurate and reliable crossover filtering in high-fidelity loudspeaker systems. With an inductance of 1.5 mH and a DC resistance of just 0.69 Ω, this component is ideally suited for use in bass and midrange crossover networks, where maintaining signal integrity and minimising power loss is essential. Whether you are building a new set of speakers from scratch or upgrading an existing design, this coil provides the consistency and performance demanded by discerning audio enthusiasts and professional cabinet builders alike.

Constructed with 21 AWG wire and wound on a ferrite tube core, the coil achieves a compact form factor with an outer diameter of 32 mm and a total height of 26 mm, making it easy to integrate into tight enclosures. The winding width of 20 mm and a core diameter of 15 mm contribute to its stable electrical characteristics, while the ±5% tolerance ensures predictable behaviour across production batches. The central mounting hole of 5 mm and a recess diameter of 12 mm simplify secure installation onto crossover boards. With a wire diameter of 0.71 mm, the coil handles moderate current levels without excessive heating, preserving the clarity and detail of your audio signal. This Intertechnik component is a dependable choice for achieving precise frequency division in your next speaker project.
