APPLICATIONS
These 6.5”ultimate sounding quality Bass-Midrange drivers have
been designed to match advanced studio monitoring
requirements for proximity monitoring.
The exceptional sound accuracy of these units results from
a careful design using A/B listening tests to select technological
solutions, which authorizes their use up to 2.5kHz without any
compromise, and up to 4.0kHz with full preservation of dynamic
behavior (Compromise is on directivity pattern only).
Optimum Bass-Reflex loading is situated between 12L and 16L
tuned from 45Hz to 40Hz.
DESIGN CONCEPT
DEFLECTION CONTROLLED DIAPHRAGM optimized for dynamic
damping.
DEFLECTION CONTROLLED DIAPHRAGM technology
consists in optimizing the shape and material of the diaphragm so
that it works as a mechanical transmission line, to avoid breaking
modes as well as mechanical threshold which destroy sound quality.
This leading edge technology offers substantial sonic advantages.
Among them: sound coherency, fast transients, stable sound imaging,
high sensitivity, wide frequency range and reduced directivity pattern.
SOFT EXCURSION LIMITING. The
SOFT EXCURSION LIMITING mechanism is
a special S-profile design of the rubber surround avoiding voice-coil
bottoming which destroys driver functionality instantaneously.
The cone excursion is progressively limited to +/- 8mm, introducing
a soft clipping which totally protects loudspeakers from
over-excursion damage.
COMPACT MAGNET SYSTEM. Its design has been specially optimized
to obtain maximum transducing efficiency while avoiding unlinear
behavior such as coil inductance variation with position,
flux modulation, harmonic distortion, rest position offset, air compression,
and off-axis voice-coil pushing.
Its design incorporates a T-shaped pole piece, and a flux stabilization
ring. It also takes into consideration demagnetization at cold
temperatures.
INTERCOOLER SYSTEM (patented). Entirely integrated into the
loudspeaker itself, the INTERCOOLER SYSTEM extracts the heat
produced by Joule effect in the voice-coil by the means of an air
flow directed through the heatsink rims of the basket by the motion of
the dust-cap and the spider.
The gain brought about by this technology is over 20 % of extra
power, so for example, a 3”coil according to this design has the same
power handling capacity as a classical 4”one.
