Duelund VSF & CAST Capacitors

Duelund VSF 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 up to 200 Volts DC 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.

Duelund CAST Capacitors
The Duelund CAST Capacitor is our no holds barred flagship capacitor.
The construction builds on the foundation of our Virtual Stack Foil design but does so with the addition of a proprietary WPIO dielectricum which necessitates several days of impregnation under high pressure.
This creates a form with incredible damping properties giving a mechanical stability hitherto unheard of.
On top of this casting process, a ring of hard pressed paper strengthens the damping properties of the design helping music flow effortlessly.
The Duelund CAST capacitor is available for speaker use and as the CAST 630v for DC-applications. Available as pure copper or pure silver.

The Duelund CAST capacitors
are designed for speaker use, they are rated up to 200 Volts DC and are available in:
Copper - CASTCU (0.1uF to 40uF)
Silver - CASTAG (0.1uF to 8.2uF) please ask for a quote for values above this range.

The Duelund CAST DC capacitors
are for signal applications in amplifiers and pre-amplifers. They are rated at 630 Volts DC and are available in:
Copper - CASTDCCU (0.22uF to 2.2uF)
Silver - CASTDCAG (0.1uF to 2.2uF) please ask for a quote for values above this range.
