Buy coils

Looking for the perfect coil for your audio project? SoundImports offers a wide range of coils essential for accurate frequency filtering within crossover networks. Our coils ensure refined sound quality in any audio setup.

What is a coil?

A coil, often also known as an inductor, is a passive two-terminal component used in electrical circuits to store energy in a magnetic field. Coils are indispensable in crossovers and other audio applications where current control and filtering of signals are essential for sound quality.

What are coils used for?

In audio applications, coils are used to filter and refine the frequency response of loudspeakers. They provide resistance to alternating current and are often used to pass low frequencies and block high frequencies, making them essential in the design of crossover networks.

Types of coils

Air coils: Use air as a core and are ideal for signals with low distortion.
Ferrite core coils: Contain a ferrite core that helps increase the inductivity of the coil.
Copper foil coils: Are known for their low resistance and are excellent for high-quality crossovers.
Iron core coils: Use an iron core to achieve higher inductance with a smaller coil.
Waxed litz wire coils: Offer reduced resistance by using many thin, individually insulated wires.
Toroidal coils: Have a toroidal core and offer efficient inductance with minimal electromagnetic interference.
Transformer coils: Specially designed for transforming voltages and currents in electronic devices.

Which coil should I choose?

Choosing the right coil depends on your specific audio needs and the application within your project. Pay attention to the inductance value, which determines the amount of resistance to change in current, as well as the wire type and physical size that can affect the final sound quality. The coil should be compatible with the impedance of your speakers and be able to handle the desired crossover frequency.
