Intertechnik HQR32/1.2/71 | 1,2 mH | 0,61 Ω | 5% | 21 AWG

The Intertechnik HQR32/1.2/71 is a precision-engineered 1.2 mH tube core coil, designed to deliver accurate and reliable performance in high-fidelity loudspeaker crossover networks. This iron core inductor is an ideal choice for audiophiles and DIY speaker builders seeking to achieve clean, well-defined frequency separation in multi-driver systems. Its robust construction ensures consistent behaviour over time, making it suitable for both new designs and upgrades to existing speaker projects.

This coil excels in low-pass and band-pass filter applications where a moderate inductance value is required. With a DC resistance of just 0.61 Ω, it minimises signal loss and power dissipation, preserving the dynamic range of your audio system. The ±5% tolerance guarantees that each unit performs to specification, allowing for predictable crossover behaviour and repeatable results across multiple builds.

Technically, the HQR32/1.2/71 features a 21 AWG winding on a 15 mm diameter core, with an outer diameter of 32 mm and a total height of 26 mm. The winding width is 20 mm, and the coil includes a 5 mm central mounting hole with a 12 mm recess for secure installation. These dimensions make it compatible with standard crossover boards and enclosures. The iron core construction provides high inductance in a compact form factor, while the tight tolerance ensures accurate filtering.

For your next speaker project, this Intertechnik coil offers a dependable solution for achieving precise crossover slopes and maintaining signal integrity. Its combination of low resistance, consistent inductance, and robust build quality makes it a valuable component for any serious audio design.
