Monitor Audio Loudspeaker Platinum Series - Manual (Page 16)

Anti-Resonance Composite (ARC) baffles, plinths and
mid-range driver housings
The front baffles, plinths and mid-range driver
housings for the Platinum series of loudspeakers
are cast from ARC material, a thermo-set polymer
loaded with minerals to provide very inert,
optimally-damped components. Refined for Platinum
by Monitor Audio’s engineers, this type of material
is used for leading-edge automotive design and is
ideal for acoustic applications where a high degree
of structural rigidity and vibration damping is
required. ARC material is cast to form a Tapered Line
Enclosure (TLE) for Platinum’s mid-range drivers.
The TLE is designed to prevent the propagation of
standing waves and modal resonances.
HiVe ® II High Velocity reflex port
Platinum employs a new type of port technology,
which uses a straight rifled design to accelerate air
flow and reduce turbulence. HiVe II technology has
the ability to move air in and out of the cabinet more
quickly than a conventional port, bringing powerful
bass and a superior transient response.
