Intertechnik COT92/6.8/14 | 6.8 mH | 0.70 Ω | 5% | 15 AWG | Corotherm Coil

The Intertechnik Corotherm heat-resistant coil offers a robust solution for demanding audio crossover networks, delivering consistent performance even under thermal stress. With an inductance of 6.80 mH and a generous ±5.0% tolerance, this iron core coil is engineered to maintain precise frequency division in high-power speaker systems. Its primary use cases include professional loudspeaker enclosures, high-fidelity home audio installations, and any application where long-term reliability and stable impedance are critical.

Technically, the Corotherm features a 1.32 mm diameter copper winding, which ensures low signal loss and efficient current handling. The DC resistance is a mere 0.70 Ω, minimising power dissipation and preserving system efficiency. The coil’s external diameter measures 92 mm, with a total height of 39 mm and a winding width of 33 mm. It incorporates a central bore of 5 mm and a recess diameter of 25.5 mm, facilitating straightforward mounting. The core diameter is 30 mm, and the entire assembly is built to withstand elevated temperatures without degrading performance.

This coil is an ideal choice for audiophiles and installers seeking a durable, high-quality component that maintains crossover accuracy in challenging thermal environments. Its construction reflects Intertechnik’s commitment to precision and reliability in audio engineering.
