Intertechnik HQG36/1.8/85 | 1.8 mH | 0.27 Ω | 5% | 20 AWG | Bell Core Coil

The Intertechnik Bell-Core Coil, with an inductance of 1.80 mH, represents a premium choice for audiophiles and loudspeaker builders seeking precise frequency filtering in crossover networks. This high-quality iron core coil is designed to deliver reliable, consistent performance, ensuring that your audio projects achieve the clarity and accuracy demanded by discerning listeners. Whether you are constructing a new set of speakers, upgrading an existing design, or repairing a vintage system, this coil provides the dependable inductive element required for effective signal management.

Ideal for use in passive crossover circuits, this coil excels at separating audio frequencies to direct the correct range to each driver—be it woofer, midrange, or tweeter. Its robust construction makes it suitable for both DIY enthusiasts and professional audio engineers who require repeatable results in custom loudspeaker builds. The 1.80 mH value is particularly useful for creating precise low-pass or band-pass filters, contributing to a cohesive and natural soundstage.

Technically, the coil features a 0.85 mm copper wire wound on a high-grade iron core, offering low DC resistance and excellent current handling. The ±5.0% tolerance ensures accurate inductance values for predictable crossover behaviour. The HQG36 core material minimises core losses and distortion, preserving signal integrity even at higher power levels. This attention to detail makes the Intertechnik Bell-Core Coil a reliable component for achieving refined audio performance in any high-fidelity loudspeaker system.
