Ferrobar 56 orsós ferritmagos tekercs

The Intertechnik DR56/3.9/140 Ferrobar Coil is a premium iron core inductor designed to deliver precise and reliable performance in high-fidelity loudspeaker crossover networks. With an inductance of 3.9 mH and a generous 15 AWG wire diameter, this coil is ideal for demanding audio applications where accuracy and low signal degradation are paramount. Whether you are building custom speakers, upgrading existing designs, or restoring vintage audio equipment, this component ensures clean, transparent sound reproduction by effectively filtering unwanted frequencies.

Technical excellence is at the heart of this coil. It features a low DC resistance of just 0.206 Ω, minimising power loss and maintaining signal integrity even under load. The ±5% tolerance guarantees consistent performance across production batches, while the robust Ferrobar core construction reduces distortion and enhances linearity. With an outer diameter of 56 mm, a winding width of 51 mm, and a total height of 61 mm, it fits comfortably into most crossover layouts. The central hole diameter of 4.5 mm and core diameter of 33 mm allow for secure mounting and easy integration.

This coil is an excellent choice for audiophiles and DIY enthusiasts seeking to achieve accurate crossover slopes without compromising sound quality. Its combination of low resistance, precise inductance, and durable build makes it a reliable foundation for any serious speaker project.
