| The Sapphire is a highly refined loudspeaker providing fast clean bass with a
pure and clean midrange. Several different design techniques are incorporated into a
single unit to deliver what we believe is superior sound reproduction. Handcrafted
cabinets made from the finest Australian and imported timbers house new and innovative
design ideas. The slim lines of the Sapphire will appeal to many while the simple but
elegant cabinet will fit both modern and traditional decors. Each Sapphire is made as a
pair from start to finish, no"production line" techniques are employed in it's
assembly. Every component is tested and ensured of meeting the quality required before
being applied. The Sapphire is well named as being a timeless precious gem to be enjoyed
for many years to come.
The Sapphire is a five driver two way design using Damped Polymer Composite (DPC) magnetically shielded drivers. These drivers use low loss rubber surrounds to eliminate the possibility of deterioration over time. The heart of the drivers, including the tweeter, utilise Hexatech Aluminium wire voice coils wound on Aluminium formers, this provides superior power handling and eliminates dynamic compression due to heating. The midrange drivers have a huge 75mm voice coil which evenly drives the shallow profile cone, reducing cone break up and reducing distortion at high power levels. The tweeter is a soft dome type incorporating low viscosity Ferrofluid cooling. The bass response of the Sapphire is fast and extended due the special loading techniques used for the four 160mm drivers. The upper pair of bass drivers are loaded using a sealed enclosure, this provides very fast, transient bass. The lower pair of drivers are loaded in their own enclosure by means of a carefully tuned quad reflex design. Four specially selected tuned resonant "ports" are carefully positioned in different areas in the cabinet to provide smooth and extended bass response to below 35Hz. The cabinet is heavily damped with acoustic absorbing materials placed with the aid of computer modelling for maximum effect. The cabinet is also extensively cross braced with individual wooden "bars". These are shaped to minimise the possibility of interaction with sound waves travelling inside the enclosure.
The cabinet itself is constructed of MDF (medium density fibre) up to a thickness of 40mm. Hardened steel spikes are also provided with every loudspeakers which are secured to the cabinet by means of integral steel threaded inserts. The loudspeaker is wired internally with heavy gauge low loss silver plated cable and provided with high quality gold plated dual terminals suitable for bi-wiring or passive bi-amplification.
