Intertechnik HQR32/068/71 | 0,68 mH | 0,39 Ω | 5% | 21 AWG

The Intertechnik HQR32/068/71 is a precision-engineered 0.68 mH iron core coil designed to elevate the performance of your loudspeaker crossover networks. Manufactured by the trusted German brand Intertechnik, this component ensures reliable and accurate signal filtering, making it an essential choice for audiophiles and DIY speaker builders alike.

This coil is ideally suited for use in passive crossover circuits, where it effectively manages low-frequency drivers by blocking unwanted higher frequencies. Whether you are constructing a new set of bookshelf speakers, upgrading an existing hi-fi system, or restoring vintage audio equipment, this inductor delivers consistent and transparent sound reproduction. Its robust construction also makes it suitable for demanding audio applications where minimal signal loss is critical.

Technically, the coil features a DC resistance of just 0.39 Ω, which helps maintain amplifier damping and reduces power loss. The winding uses 21 AWG wire with a diameter of 0.71 mm, ensuring efficient current handling. The core has an outer diameter of 32 mm and a total height of 26 mm, with a central mounting hole of 5 mm for secure installation. The tolerance of ±5% guarantees precise inductance value, while the 0.68 mH rating is ideal for many standard crossover designs.

With its high-quality construction and exacting specifications, this Intertechnik tube core coil is a dependable choice for achieving clean, accurate crossover performance in your next audio project.
