The
Broadcast Monitor Heritage
We are
particularly pround of our long and close association with the B.B.C. under
whose Approved Accerditation we manufacture the world renowed LS3/5a and LS5/9
Broadcast Monitors. Rogers is
one of only a select handful of Approved Licensees who have proved they can
maintain the impeccable manufacturing standards required for their production. It is those
very same standards which form the benchmark for our total production and
Quality Control Procedures.
LS5/9
The LS5/9
marks 20 years of close association between the design and development
departments of the B.B.C. and Rogers. It is compact system designed for studio
monitoring purposes, and capable of outstanding resolution and authority in a
matching audio system.
At the heart
of every conventional loudspeaker ies the voice coil - crucial to its power
handling and resistance to overload. At Rogers we
design and produce our own very high temperature voice coils as well as all the
tooling required to wind and handle them.
Polypropylene
has been recognised for some time as an excellent cone material combining
rigidity, low mass and self-damping. Againg we
make our own tooling and vacuum-form all our cones giving us complete control
over virtually every aspect of the bass unit performance.
Surrounds
and spiders are specially selected or manufactured to our specific
requirements.
The latest
generation of metal dome tweeters has allowed us to make significant advances
in the high frequency response of our new models. Clean,
transparent, detailed sound with extended response is the hallmark of this
exciting unit. Power
handling, sensitivity and damping are enhanced by the use of ferro-fluid in the
magnet gap.
Matching Stand S-59 - The S Series
Stands, designed specifically to match the LS3/5a and the LS5/9, are
constructed from heavy duty steel tube and sheet to achieve rigidity, low
resonance characteristics and high mass. They are
fitted with adjustable carpet piercing spikes to give maximum stability.
