Duelund Inductors

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.

What are Duelund inductors?

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. 

Why choose Duelund inductors?

Duelund inductors offer many advantages over conventional coils, such as:

  • Superior sound quality: Duelund inductors feature very low resistance, low inductance, and low distortion, which means they can deliver a clear, natural, and dynamic sound with minimal loss or interference.
  • Reduced microphony: Duelund inductors have a very high mechanical stability and damping, which means they can resist vibrations and noises that could affect the sound quality.
  • Long-lasting durability: Duelund inductors have a very high thermal stability and reliability, which means they can withstand high temperatures and currents without degrading or failing.
  • Unique design: Duelund inductors have a distinctive appearance and feel, which reflects their craftsmanship and quality. They are also hand-made and individually tested to ensure their consistency and accuracy.

What makes Duelund inductors unique?

Duelund inductors are unique because they are the only WPIO vacuum impregnated air core copper and silver foil inductors available today. They are the result of decades of research and development by Steen Duelund and his team at Duelund Coherent Audio. They represent the pinnacle of audio engineering and design, and they are unmatched by any other product on the market.
