Intertechnik HQG36/2.7/67 | 2.7 mH | 0.46 Ω | 5% | 22 AWG | Bell Core Coil

The Intertechnik Bell-Core Coil with an inductance of 2.70 mH is a premium-grade iron core component designed to elevate the performance of your loudspeaker crossover networks. Manufactured to exacting standards, this coil ensures accurate frequency filtering, which is essential for achieving a balanced and natural sound reproduction in any high-fidelity audio system.

This coil is ideally suited for use in passive crossover designs, where it can be employed in low-pass or band-pass filter sections to precisely control the signal sent to woofers and midrange drivers. Whether you are building custom speakers from scratch or upgrading an existing pair, the Bell-Core Coil provides the reliability and consistency required for critical audio applications. Its robust construction makes it a dependable choice for both hobbyist and professional loudspeaker projects.

Technically, the coil features a 0.67 mm copper wire diameter, wound on a high-quality iron core to minimise core losses and maintain stable inductance over a wide frequency range. The inductance value of 2.70 mH is held to a tight tolerance of ±5.0%, ensuring predictable and repeatable filter behaviour. The HQG36 designation indicates a carefully selected core material that optimises magnetic flux, reducing distortion and improving overall signal integrity. This attention to detail makes the Intertechnik Bell-Core Coil a reliable building block for achieving precise crossover points and superior audio clarity.

In summary, this coil offers the perfect combination of precision, durability, and performance for discerning audio enthusiasts seeking to refine their loudspeaker systems.
