Air core coils

Air-core coils form a specialised group of electronic components essential for accurate, distortion-free signal transfer. These inductive elements play a key role in audio-frequency circuits, ensuring stable operation. These components are used primarily by professional audio engineers and dedicated hi-fi builders when designing crossovers or fine-tuning existing systems. Air-core coils are especially valuable where preserving signal purity and minimising unwanted distortion is the goal, which is why they are frequently found in the internal crossovers of high-end loudspeakers. When choosing a coil, the key decisions are the required inductance value and the wire gauge, which greatly affects the coil's internal resistance and power handling. It's also worth considering the available mounting space and physical dimensions, since these components can vary significantly in size, which in turn affects the magnetic influence they exert on nearby components. Quality materials, such as those used by Jantzen Audio and Mundorf, guarantee reliable, precise operation in every audio application over the long term. HQaudioparts currently offers more than 700 different types of coils to choose from.
