The
Osborn "C2" was designed and constructed with little
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, in
order to match whichever other Osborn Loudspeakers are used as
the main speakers, in a Home Theater system. We believe that our
design goals have been realised with this speaker. The C2 is ideal
for the heavy demands placed on a center speaker by Dolby Digital.
The cabinet is constructed from 32 mm Customwood instead of the
usual 18 mm Chipboard used by other Center Speaker manufacturers.
There is also heavy bracing from the front to back and from top
to bottom on either side of the tweeter. This ensures that the
output of the rear of the Bass Driver is more thoroughly isolated
from the sound emitted from the speaker itself. Any spurious cabinet
vibrations will result in a loss of definition and sonic purity.
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 anywhere near their
price and size. The drive units were chosen from the best available
from around the world for unrivaled speed and accuracy. As a result,
a level of transparency comparable to the rest of the range of
Osborn Loudspeakers has been achieved.
Many
center speaker manufacturers attempt to cram as many cheap drivers
as possible into a cabinet of a given size, so that prospective
buyers are impressed by the apparent complexity of the speaker.
This defeats the purpose of such a speaker. A driver with a low
frequency cut off of say, 75 Hz, still has a 75 Hz lower limit
if 2, 4 or even six drivers are used. The use of so many drivers
causes phase and other problems as each driver madly interferes
with each other. A smeared image also results, when one of the
main requirements of a center speaker is to locate voices nearer
to the viewing area. The Osborn C2 and C3 use a single, very high
quality shielded tweeter and two 7" mid/bass. A 3 way crossover
is used with one driver functioning as a mid/bass and the other
as a bass driver, which results in a more dynamic speaker with
superior bass extension. The C2 uses 2 Polykevlar drive units,
and the C3 uses 2 W Cone drive units. These speakers are flat
to 35 Hz and have usable bass to well under 30 Hz. This allows
for the entire range of human voices to be easily reproduced.
The
crossovers use some of the best components attainable. The capacitors
are imported from France and the inductors are wound in-house
as none are available commercially which meet our criteria. Each
crossover is hard wired with quality Datalink ultra high speed,
ultra wide bandwidth cable.
The
speaker is designed to be placed under or on top of your Television.
The cabinet is exceptionally strong and is able to easily withstand
the weight of the heaviest Televisions. The speaker may also be
placed on top of the Television, if the top is large enough to
accommodate it. The speaker is covered in a high quality black
vinyl veneer to match the majority of televisions. This finish
is more durable and scratch resistant then quality timber veneers.
The timber finish of your choice is an optional extra if it is
required to match the main speakers or decor.
Center speakers are made in black vinyl veneer as standars,
as they are usually placed under a Television. However they are
available in any required veneer.

The
above specifications show why this speaker is capable of such
extraordinary transient performance yet reveals such intimate
detail in the music. This fidelity is possible due to the fine
tolerances and light weight of the driver voice coils. This minimal
compromise design allows the natural life and excitement of the
original live performance to be faithfully reproduced.
