The
Osborn Epitome has been designed and constructed in Australia,
without compromise, in order to obtain the highest possible sound
quality. The only criteria in the choice of components, materials,
size and cost is the achievement of the ultimate sound quality.
We believe that our design goals have been realised with this
speaker, now in its sixth generation.
The Osborn Epitome
is one of the finest speakers in the world, with unmatched speed
and transient attack. But matched with the optional Epitome Bass
unit the performance becomes extraordinary. The dynamics, bass,
transparency and sheer power becomes unmatched by virtually any
other speaker at any price. No other speaker combination can deliver
the whole weight, power and authority of a full symphony orchestra.
From the tinkle of the tiniest bell to the blast of a brass cannon,
to the depth of a giant 32 foot pipe organ. It is not only the
bass which is improved with the addition of the Bass unit, the
entire audio spectrum is improved. Transparency, dynamic contrasts,
and detail are transformed. And of course the bass becomes unsurpassed
in speed, power, depth and detail. The sound stage is also greatly
enhanced in both width and depth and in the pin point imaging.
Several of the
world's best speakers were used as references in the design of
these speakers. We believe that the sound quality of these speakers
is superior to all the references.
The drive units
were chosen from the best available from around the world for
unrivalled speed and accuracy. As a result, a level of transparency
comparable to the best Electrostatic speakers has been achieved.
The crossovers
use the best components attainable. The capacitors are imported
from America and the inductors are wound in-house as none are
available commercially which meet our criteria. Each crossover
is hard wired with specially selected ultra wide bandwidth, ultra
high speed data transfer cable and weighs about 6 kilograms.
Only the best
quality Turntable/CD Player and Amplifiers were used in the design
of these speakers. High quality timber veneers are used on these
speakers. Standard finishes are Jarrah and Bubinga. The cabinets
are shaped using high precision, computer controlled milling equipment.
All models are constructed from 32 mm Customwood and are heavily
braced. The Grand Epitome is also fully lined with
a felt/lead/felt sandwich as used on the Grand Monument Reference. Both
models are exceptionally heavy, solid and are acoustically inert.
High quality natural timber veneers are used, and every cabinet
is carefully hand finished to ensure a superb quality finish which
will grace any living room.
These speakers
have a number of outstanding features - the ability to separate
instruments and place them firmly and accurately on a sound stage
of uncanny width and depth: The instruments retain their correct
pitch, tone and shimmer: Dynamic range and speed unmatched by
any speaker in any price range and the ability for drums to retain
their impact and depth, with or without the addition of the Epitome
Bass unit. The Epitome Bass Unit can be added at any time and
the crossover is switchable for use with or without the bass unit.

The Grand Epitome Reference features heavy lead lining to all exterior surfaces. The same heavy bracing is used, but all areas between the bracing are covered by a unique sandwich lining. Heavy acoustic felt is used to separate the heavy lead sheet from the cabinetry. A further layer of heavy acoustic felt is placed over the lead and the entire sandwich is stapled to the walls of the cabinet. This result is what is effectively a box within a box. Wrapping the outside of the speaker is similar to knocking on a brick. This totally inert cabinet construction results in the ultimate sound reproduction.
