Intertechnik HQP56/2.2/32 | 2.2 mH | 0.23 Ω | 5% | 16 AWG | Mushroom Core Coil

The Intertechnik Ferrobar mushroom-shaped ferrite core coil, rated at 2.00 mH, is a premium component designed to elevate the performance of your loudspeaker crossover networks. Its distinctive shape and robust construction make it an ideal choice for audiophiles and DIY enthusiasts seeking precise frequency filtering with minimal signal degradation. Whether you are building high-fidelity home speakers, upgrading existing designs, or crafting professional studio monitors, this coil ensures accurate division of audio frequencies, allowing each driver to operate within its optimal range for a cleaner, more natural sound.

Engineered with a copper wire diameter of 1.32 mm, the coil achieves a low DC resistance of just 0.23 Ω, which significantly reduces power loss and heat buildup even under demanding conditions. The ferrite core provides stable inductance with a tight tolerance of ±5%, ensuring consistent performance across production batches. With an outer diameter of 56 mm, a total height of 35 mm, and a winding width of 23 mm, the coil fits neatly into compact crossover layouts. The central hole diameter of 5 mm and recess diameter of 25.5 mm facilitate secure mounting. This combination of technical precision and thoughtful design makes the Intertechnik Ferrobar a reliable choice for achieving transparent, distortion-free audio reproduction in any serious loudspeaker project.
