RS brings to life the first entirely new capacitor design from Duelund Audio in half a decade.

3 years in development, RS introduces the unmatched mechanical stability of the Duelund CAST technology combined with a size not much larger than standard capacitors.

At its core, RS fuses CAST DNA with lessons learned from our illustrious VSF series – bringing state of the art performance into a much more available format.

We are confident the RS will bring state of the art performance to any system.

In the words of Humblehomemadehifi: the Duelund RS Copper Capacitor is a real no brainer, once you have put this capacitor in your loudspeaker crossovers you will never need to tweak again!
