Heritage Duke

Small can often be beautiful. And the sound that the Duke delivers, despite its diminutive size, is beautifully rich and smooth, covering frequencies down to 38 Hz.


In fact, it sounds as outstanding as the rest of the Heritage series – provided your room is not too large.
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.
In our opinion it is the perfect start-up model for your first high-end system. A must for the true audiophile whose listening space isn't enormous.

The new Duke
Cell tweeter designed with the latest Accuton technology.
Bass drivers with higher transparency and resolution using the latest Accuton technology.
Improved crossover using leading Mundorf components.
