Intertechnik TO10/5.6 | 5,6 mH | 0,22 Ω | 5% | 16 AWG

The Intertechnik Torobar iron-core toroidal coil, with an inductance of 5.60 mH and a tolerance of ±5.0%, is a premium component designed for demanding audio enthusiasts and professional speaker builders. This coil excels in crossover networks, where its stable inductance ensures accurate frequency division between drivers, minimising phase shifts and preserving the integrity of the original signal. Its low DC resistance of just 0.22 Ω makes it particularly suitable for high-power applications, such as woofers and subwoofers, where efficiency and minimal power loss are critical for dynamic, distortion-free bass reproduction.

Technically, the coil features a 1.30 mm diameter copper wire, which contributes to its low resistance and excellent current handling capability. The iron core is engineered to maintain consistent inductance levels across a wide frequency range, reducing the risk of saturation even under demanding loads. With an outer diameter of 74 mm, a central hole of 5 mm, and a total height of 33 mm, this TO10 series component is compact yet robust, fitting neatly into most crossover layouts. The ±5% tolerance ensures reliable performance, making it an ideal choice for both replacement and new designs. Whether you are upgrading an existing system or building a custom loudspeaker from scratch, this Intertechnik coil delivers the precision and sonic clarity required for high-fidelity audio.
