Model Information

[Tranquility Bass]

Duntech Baron


 

The Baron also has a five driver system symmetrically arranged on a vertical axis to ensure time alignment.
The bass and mid-range drivers have diecast aluminium chassis. The bass drivers use a vented magnet system and feature a special pulp paper cone.

The mid-range drivers are double magnet design and have rubber suspension for low resonance.

The double chamber tweeters are 25mm (1") dome type, with a fabric diaphragm and ferrofluid for efficient cooling and damping.

The cabinet is designed to provide optimum rigidity and its size has been matched to the performance requirements of the drivers. The mid-range drivers have separate sealed enclosures.

Acoustic felt is matched to the requirements of the loudspeaker and tailored to the geometry of the enclosure.

The loudspeaker is covered with acoustically transparent cloth and the woodwork lacquered satin black and finished with gloss silver trim.                       

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.
