Duelund PIO Cast Copper Air Core Inductor 12awg

Welcome to the world of Duelund inductors, the ultimate choice for audiophiles who demand the best sound quality and performance from their audio systems. Duelund inductors are made by Duelund Coherent Audio, a Danish company that was founded by the late Steen Duelund, a legendary audio engineer and designer. Duelund inductors are based on his innovative and groundbreaking approach to audio components, which renders all previous attempts at audio capacitors and coils obsolete.

Duelund inductors are high-quality air core coils that are used in audio crossover networks, filters, or electronics. They are composed of pure metal foils that are wound onto a compressed paper former, with the foils insulated by waxed/oiled paper. The inductors are fully vacuum impregnated under high pressure, using a proprietary WPIO dielectricum that enhances the electrical and mechanical properties of the coil.

Duelund inductors come in two types: our top of the line potted CAST and non potted  JDM. Both inductors use either copper foil or silver foil as the conductor.

The Duelund Copper WAX/PIO inductors are composed of foils that are wound onto a compressed paper former with the foils insulated by waxed/oiled paper. The CASTing process utilises a proprietary WPIO dielectricum which necessitates several days of impregnation under high pressure. They are available in copper foil or silver foil.

This creates a form with incredible damping properties giving a mechanical stability hitherto unheard of. This stability is then further augmented by a rigorous casting process, keeping the inductor perfectly stable.On top of this casting process, a ring of hard pressed paper strengthens the damping properties of the design helping music flow effortlessly.
