Intertechnik E130/056/300 | 0.56 mH | 0.07 Ω | 3% | 9 AWG | Choke Coil

The Intertechnik Air-core Coil with 0.56 mH inductance represents a premium choice for audiophiles and loudspeaker designers who demand uncompromising signal purity. Crafted from high-grade copper wire, this air-core inductor eliminates the core saturation and hysteresis distortion common in ferrite-based alternatives, ensuring transparent, uncoloured sound reproduction across the entire frequency range.

This coil is ideally suited for high-end crossover networks in multi-way speaker systems, where precise filtering is critical to maintaining phase coherence and tonal accuracy. Whether you are building custom studio monitors, upgrading existing loudspeakers, or designing bespoke audio installations, the low DC resistance of 0.07 Ω minimises power loss and thermal drift, preserving dynamic headroom even at elevated listening levels.

Technically, the coil features a 3.00 mm copper winding diameter, which contributes to its exceptionally low resistance and excellent current handling capability. The ±3.0% tolerance ensures consistent performance between units, vital for matched stereo pairs or production runs. With a total height of 79 mm, this robust component integrates easily into most crossover layouts while maintaining optimal air circulation for thermal stability.

For discerning audio enthusiasts seeking measurable improvements in clarity and imaging, this Intertechnik air-core coil delivers reliable, high-fidelity performance that honours the integrity of the original signal.
