Duntech Prince                   
                         

Making Waves - Prince           The Prince embodies many Duntech firsts...
Hand coated Kevlar drivers Reverberant field control Extremely high quality crossover High frequency acoustic filter In room response to infra-sonic frequencies Tri-wiring via gold plated bars
The Prince features a five driver layout, symmetrically arranged on a vertical axis and time aligned.             The bass drivers are formed from a cast and hand coated Kevlar cone material. The voice coil is a long throw design producing the lowest levels of distortion and compression.             The midrange drivers are also based on a hand coated Kevlar cone which perfectly matches the bass drivers. The dust cap on this driver incorporates a specially matched diaphragm to ensure smooth high frequency performance for above the crossover point.             A symmetrically lathed and vented pole piece is used for both drivers. The basket material is magnesium.             The tweeter is based on a diaphragm with a special profile to optimise the high frequency response. A cone shaped pole piece is used to minimise cavity resonances and an additional rear chamber further improves the damping of the tweeter. In front of the tweeter Duntech has mounted a unique acoustic resonance filter to provide unprecedented clarity at high frequencies.             At the rear of the speaker a specially controlled tweeter provides reverberant energy in the room to exactly mimic the sound field in a real concert hall.             The lower woofer is loaded by a transmission line to provide extremely low frequency output in the listening room.             The front of the enclosure is treated with die cut felt of precise properties to suppress the box diffraction effects.             The cabinet is made of 25mm thick MDF with extensive bracing throughout. Each driver is accorded its own enclosure.             The crossover is a first for Duntech, employing a non-ferrous substrate. The inductors are wound from seven separate strands of wire laid in a computer driven orthocyclic winding. The capacitors are actually constructed from multiple capacitors in each package to provide very fast rise times and low loss factors.             The speaker is provided with six sets of terminals for tri- wiring, bi-wiring or normal operation.             The Prince is available in a choice of Queensland Walnut, Rosewood or Piano Black.
