Description

It was not called "the world's most accurate loudspeaker" for nothing

The Sovereign is the flagship of the Duntech range and acknowledged by experts as the finest loudspeaker in the world, certainly the most accurate.
The Sovereign uses a seven driver system with the drivers symmetrically arranged on a vertical axis and time aligned.
The woofers have rigid magnesium diecast baskets and use PHA cone material. A vented, long throw magnet system reduces air movement noise. These low distortion drivers incorporate hexacoil technology for very high power handling and display excellent linear dynamic response.

The bass drivers feature a large diameter aluminium voice coil and former, a wide dispersion pattern, excellent phase characteristics and fast transient response. The soft domed, mid-range drivers are aperiodically damped and the use of ferrofluid dissipates heat very efficiently. The double chamber tweeter exhibits extremely linear response with low distortion and wide dispersion. The high precision, vented pole plate and pole piece is constructed around a special high-flux ferrite magnet and the textile diaphragm is hand coated.
The crossover is a highly complex, first order type with high power handling. The fibreglass printed circuit board is mounted in it's own separate cavity. Polypropylene capacitors are used for their stability, high voltage, low loss and low inductance, together with aircore inductors. Resistors are high powered ceramic type.
Input terminals are gold plated on nickel and are an exclusive Duntech Audio design.

The terminals are spaced for easy access and accept a banana, spade or wire connection.
The cabinet is made of custom wood laminated in thickness up to 33mm (1.3"). It is heavily braced with hardwood to reduce resonances and vibration to inaudible levels.
An optimized, sealed enclosure is used to provide accurate reproduction in preference to a vented enclosure which very often produces a woolly or ill-defined sound.
The cabinet is step baffled to provide time alignment. Selected grades and sizes of foam are strategically positioned internally to optimize driver performance.
Each driver is mounted on gaskets in a separate enclosure. Drivers are fixed with hardened steel machine screws in metal threads.
Sound absorbing, organic felt is used extensively to minimize diffraction distortion and is hand tailored to the shape of the cabinet front.
The Sovereign is available in a choice of hand finished, high quality, wood veneers. Customized finished are also available upon request. The grill frame is an integral part of the loudspeaker design and is covered in acoustically transparent black cloth.
