Marquis
The Marquis, like all Duntech’s designs are also a time aligned, five driver arrangement loudspeaker.
The bass and mid-range drivers have diecast magnesium chassis. The bass drivers use a vented magnet system and feature a special, coated, pulp paper cone.
The mid-range drivers are double magnet design and have rubber suspension for low resonance.
The double chamber tweeter is 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. All 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 grill is covered with acoustically transparent cloth and the cabinet is hand finished in high quality wood veneers.
