HIGH
PERFORMANCE REFERENCE MONITORING
A main
monitor system for Recording and Post-production studios where the requirement
is for high performance, natural sound reproduction. With a single coherent
wavefront thanks to the 15" Dual Concentric™ point source driver, sound
presented to the engineers is remarkably distortion free. And with the enlarged
monitoring position provided by this remarkable drivers wide dispersion,
monitoring with the System 15 DMT II is particularly fatigue free.
The
availability of new materials and manufacturing processes has allowed Tannoy to
design the System 15 DMT II from first principles, producing an all new Dual
Concentric™ monitoring system with all the classic benefits of single point
source monitoring combined with an exceptionally detailed but fatigue-free
sound.
The style of
the cabinet is not arbitrary, it has been arrived at by considering the
acoustic principles of diffraction and energy storage.
The trim
rings around the rubber surrounds are there to smooth out the otherwise
discontinuous contour to the HF wavefront.
The smooth
lines around the port tubes ensure laminar air flow at low frequencies where
the air in the ports has maximum velocity.
The shapes
of the LF cones continue the hyperbolic waveguide for the HF energy
propagation.
The cabinet
bracing and internalconstruction ensures that the HF unit can deliver the
detail into the sound field.
The
application of the Differential material Technology approach to component
behaviour ubder vibration and magnetic fields has lead to custom crossover
components, custom cabling and split crossovery design being employed.
