The Duke is a 2-way system, comprising a newly developed 7″ ceramic bass/mid-range driver and a new tweeter, which uses pioneering technology to achieve diamond-like performance.
A must for the true audiophile with a modest listening space.
We use Jorma Design internal wiring, for its exemplary quality and performance. Handmade in Sweden, the cables use separate + and – for enhanced shielding and the highest quality Copper.
This offers natural, transparent sound; the perfect choice for our speakers.
Cables are integral components, so they must work harmoniously with our precision design and build. Jorma Design delivers exactly what a Marten speaker demands.
Music is your environment, as much as your sofa or the pictures on your wall: it enhances the space around you. The Heritage series fits seamlessly in to your home, giving you visual appeal as well as award-winning sound.
