Audyn COT62/2.7/14 | 2,7 mH | 0,37 Ω | 5% | 15 AWG

The Intertechnik Corotherm heat-resistant coil delivers exceptional stability and performance for demanding loudspeaker crossover networks. Engineered to withstand elevated temperatures, this iron core inductor ensures consistent filtering characteristics even under sustained high-power operation, making it an ideal choice for professional audio installations, high-fidelity home systems, and custom speaker builds where reliability is paramount.

This 2.70 mH coil is particularly suited for low-pass and band-pass filter sections in multi-way speaker designs, effectively managing the transition between drivers while minimising signal degradation. Its robust construction supports use in both passive crossover upgrades and new DIY projects, offering audiophiles and technicians a dependable component that maintains sonic integrity over extended listening sessions.

Technically, the coil features a 1.32 mm copper wire diameter, resulting in a low DC resistance of just 0.37 Ω, which reduces power loss and heat buildup. The 62 mm outer diameter and 28 mm core diameter accommodate a 35 mm winding width, with a total height of 41 mm. A 5 mm central hole and 25.5 mm recess diameter facilitate straightforward mounting. The ±5% tolerance ensures precise inductance matching, critical for accurate crossover alignment.

With its heat-resistant design and carefully specified parameters, this Intertechnik coil provides a durable, high-performance solution for serious audio applications where consistent sound quality and long-term reliability are essential.
