The Osborn C1 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
cabinet is constructed from 25 mm Customwood instead of the usual
18 mm Chipboard used by other Centre Speaker manufacturers. 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 Center speaker uses a single,
very high quality shielded tweeter and the same single 5"
mid/bass that is used in the Osborn Mini Tower, except that it
is shielded for this application. This necessitates the use of
a 3 way crossover, but results in a more dynamic speaker with
superior bass extension. This speaker is flat to 50 Hz and has
usable bass to 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.
