Intertechnik COT92/5.6/14 | 5.6 mH | 0.61 Ω | 5% | 15 AWG | Corotherm Coil

The Intertechnik Corotherm heat-resistant coil delivers exceptional stability and performance for demanding loudspeaker crossover networks. Engineered to maintain precise signal filtering even under sustained high-power operation, this iron core inductor is an ideal choice for audiophile-grade speaker systems, professional sound reinforcement, and custom DIY projects where thermal reliability is paramount. Its robust construction ensures consistent crossover behaviour, preventing frequency response shifts that can compromise sound quality in high-output applications.

Featuring a 5.60 mH inductance with a tight ±5% tolerance and a low DC resistance of 0.61 Ω, this coil provides accurate filtering with minimal signal loss. The 1.32 mm copper wire diameter ensures excellent current handling, while the 92 mm outer diameter and 39 mm total height allow for efficient integration into crossover boards. The design includes a 30 mm core diameter, 33 mm winding width, and a central bore of 5 mm, with a recess diameter of 25.5 mm for secure mounting. The Corotherm construction utilises heat-resistant materials that withstand elevated temperatures, ensuring long-term reliability in active or passive crossover networks. Whether used in high-fidelity home audio, studio monitors, or live sound systems, this coil offers the thermal stability and electrical precision required for uncompromising audio performance.
