Intertechnik E130/068/300 | 0.68 mH | 0.08 Ω | 3% | 9 AWG | Choke Coil

The Intertechnik Air-core coil with a 0.68 mH inductance is a premium component designed for audiophiles and speaker builders who demand uncompromising sound quality. This low-loss coil excels in crossover networks, where precise filtering is essential to separate audio frequencies cleanly between drivers. Its air-core construction eliminates core saturation and hysteresis distortion, making it ideal for high-fidelity systems, studio monitors, and custom DIY speaker projects where signal purity is paramount.

Technically, this coil is wound with 3.00 mm diameter copper wire, resulting in an exceptionally low DC resistance of just 0.08 Ω. This minimises power loss and heat generation, ensuring efficient energy transfer and maintaining the integrity of your audio signal. The overall height of 79 mm allows for compact integration into speaker enclosures, while the ±3.0% tolerance guarantees consistent performance across production batches. The robust winding and high-quality materials reflect Intertechnik’s commitment to reliability and sonic accuracy.

Whether you are upgrading an existing crossover or building a new speaker system from scratch, this air-core coil delivers transparent, distortion-free performance. Pair it with other premium components to achieve a balanced, natural soundstage that reveals every detail in your music.
