Intertechnik HQG36/2.2/85 | 2.2 mH | 0.30 Ω | 5% | 20 AWG | Bell Core Coil

The Intertechnik Bell-Core Coil with an inductance of 2.20 mH is a premium iron core component designed for audiophile-grade loudspeaker crossover networks. This coil ensures accurate frequency division, allowing tweeters, midrange drivers, and woofers to operate within their optimal ranges for a balanced, distortion-free soundstage. Ideal for custom speaker builds, repair projects, or upgrading existing designs, it delivers consistent performance in both passive and active crossover configurations. The robust construction and precise tolerance make it a reliable choice for demanding audio applications where signal integrity is paramount.

Technically, this coil features a 0.85 mm copper wire wound on a high-quality iron core, offering low DC resistance and excellent current handling. The ±5.0% inductance tolerance guarantees repeatable results across multiple units, essential for matched pairs in stereo systems. The HQG36 core material minimises core losses and saturation effects, preserving transient response even at higher power levels. With its 2.20 mH value, this coil is particularly suited for low-pass filters in two- or three-way designs, ensuring seamless integration with other crossover components. Whether you are a seasoned DIY enthusiast or a professional audio engineer, this Intertechnik coil provides the precision and durability needed to achieve refined, natural sound reproduction in your speaker projects.
