Audyn CO92/4.7/140 | 4,7 mH | 0,52 Ω | 5% | 15 AWG

The Audyn CO92/4.7/140 Corobar Coil is a premium iron-core inductor engineered for discerning audio enthusiasts who demand the highest level of performance from their loudspeaker systems. This 4.7 mH coil is specifically designed for use in high-end crossover networks, where precise filtering is essential to achieve accurate driver integration and a cohesive soundstage. Its robust construction makes it ideal for both DIY speaker builders and professional audio designers seeking to minimise signal degradation and preserve musical detail.

At the heart of this component lies a carefully wound copper foil winding, which offers superior current handling and reduced eddy current losses compared to standard wire coils. The 1.45 mm wire diameter (equivalent to 15 AWG) ensures low DC resistance of just 0.52 Ω, allowing for efficient power transfer and minimal heat generation. With a tight inductance tolerance of ±5%, this coil guarantees consistent performance across production batches, while the iron core provides high saturation levels and stable inductance even under demanding dynamic conditions. The compact dimensions of 92 x 39 mm facilitate easy integration into most crossover boards.

Finished with Audyn’s renowned Corobar technology, this coil delivers exceptionally low distortion and a natural, uncoloured sound. Whether you are upgrading an existing design or building a new reference loudspeaker, the CO92/4.7/140 offers the reliability and sonic transparency required for critical listening applications.
