Intertechnik TO10/4.7 | 4.7 mH | 0.20 Ω | 5% | 16 AWG | Torobar Toroidal Coil

The Intertechnik Torobar iron-core toroidal coil delivers exceptional performance for demanding loudspeaker crossover networks. Engineered with precision, this 4.70 mH inductor ensures accurate frequency division, making it an ideal choice for audiophiles and DIY speaker builders seeking to refine their system’s soundstage and clarity. Its robust construction supports both high-end home audio installations and professional-grade designs where consistent, reliable filtering is paramount.

This coil excels in passive crossover applications, particularly for low-pass and band-pass filters in multi-way speaker systems. The 1.30 mm copper wire diameter and low DC resistance of just 0.20 Ω minimise power loss and heat generation, preserving signal integrity even under sustained high-power operation. The toroidal core design further reduces external magnetic interference, ensuring clean, uncoloured audio reproduction.

Technical specifications include an outer diameter of 74 mm, a central hole of 5 mm, and a total height of 32 mm, allowing straightforward integration into compact enclosures. The ±5% tolerance guarantees precise inductance matching for consistent crossover behaviour. With its iron-core construction and high-quality copper winding, the Intertechnik Torobar coil offers a durable, long-lasting solution for critical audio filtering tasks.
