[Tranquility Bass]

Duntech Viscount                       

The Viscount has a time aligned, three driver arrangement.           The bass drivers feature an advanced polymer cone and vented double magnet system. The 75mm (3") voice coil is made of aluminium wire for low moving mass.           The tweeter features hand treated, soft domed diaphragm assembly, aluminium voice coil and ferrofluid.           All drivers are mounted on gaskets in separate, sealed enclosures. The cabinet is custom wood, laminated in thicknesses up to 68mm (3") for optimum rigidity. All relevant edges are radiused to reduce diffraction.

                 

The Regent and Baron cabinets, and the stands for the Viscount and Esquire models, come with hardened steel spikes which may be used to minimise motion and increase stability.
