Duelund Coherent Audio
 Virtual stack foil capacitors


This new capacitor is the realization of a lifelong ambition. It consists of aluminium, copper or silver foil and high-density paper, soaked in pure mineral wax, treated with special lacquers made from natural materials and wrapped in paper.

The Duelund VSF capacitor is available for speaker use (100Vac) and as the Duelund VSF DC for higher voltage applications (400Vdc).

Duelund Virtual Stack Foil Capacitors



The Virtual stack foil capacitor, a capacitor made specially for loudspeaker crossovers.
This new capacitor is the realization of a lifelong ambition. It consists of aluminium, copper or silver foil and high-density paper, soaked in pure mineral wax, treated with special lacquers made from natural materials and wrapped in paper. It is without question a "green" product.

The actual construction has been overseen by Mr. Steen Duelund Chief Engineer of Duelund Coherent Audio. Mr. Duelund has dictated the capacitor's special characteristics, i.e. its flatness, giving the opportunity to create its stack-foil working manner ensuring very low inductance, forming a solid block resulting in a form free of internal resonances. Furthermore, the flatness makes it easier to achieve greater values by connecting the capacitors in parallel.

Performance
The audiophile vocabulary contains many words that attempt to describe sonic qualities of equipment and components: Immediacy, clarity, harmonic authenticity, detail, plasticity, uncolouredness etc.
While this capacitor has no problems fulfilling the promise of these words none of them encompass the sound that this component makes possible. Only one word does this: Natural

The Duelund VSF capacitors
are for speaker use, these are simple referred to as VSF range,
they are rated for 100 Volts AC and are available in:
Aluminium - VSFAL (0.47uF to 50uF)
Copper - VSFCU (0.1uF to 40uF)
Silver - VSFAG (0.1uF to 8.2uF) please ask for a quote for values above this range.

The Duelund VSF DC capacitors
are for signal applications in amplifiers and pre-amplifers.
They are rated at 400 Volts DC and are available in:
Copper - VSFDCCU (0.047uF to 2.2uF)
Silver - VSFDCAG (0.1uF to 8.2uF) please ask for a quote for values above this range.
