Model Information

[Tranquility Bass]

Duntech Princess



The Princess features a five driver layout, symmetrically arranged on a vertical axis and time aligned.
The bass drivers feature similar advantages to the Sovereign drivers, and the cone material is based on a thermo plastic polymer, reinforced with magnesium oxide.

The mid-range drivers have a powerful, ventilated magnet system with patented symmetric drive and pole piece.

The baskets are diecast magnesium and feature an aluminium former and voice coil for low moving mass. The drivers feature hand coated, rubber surround and textile dome, with selective plastic coating for optimum damping of resonances.

The tweeter exhibits excellent phase linearity and wide dynamic range. It is soft domed with soft rolloff suspension and aperiodically damped, double chamber construction.

Hexacoil technology permits very high power handling and the ferrofluid core dissipates heat very efficiently.

Acoustic absorbing material is tailored to all front surfaces of the enclosure to minimise diffraction distortion.

The cabinet is custom wood with specially designed, "figure of 8" bracing used extensively. The Princess is available in a choice of hand finished Brazilian Rosewood or Brown Oak, with acoustically transparent black cloth.



The Princess and Marquis loudspeakers come with hardened steel spikes which may be used to minimise motion and increase stability.

The spikes are mounted in recessed metal threads and a locking nut allows height adjustment to compensate for uneven floor surfaces.
