APPLICATIONS
The ”Seventy-Ten” is one of our best sellers. It was designed for Sound
Reinforcement applications in 1995, and fully exploits the capacity of
our powerful 4”magnet system, which results in a successful design.
The 7010 is a true 18” (Sd=0.128 sq.meter) while most of its competitors
are 17”, which offers extra sensitivity that can reach 1.8 dB at the
same displacement figure.
This, combined with the AES Power handling of 1kW, results in
a tremendous dynamic capacity to transduce low and very low
sound frequencies at particularly low harmonic distortion levels
in small volume enclosures.
Recommended Reflex sub-cabinet is 150L to 200L tuned from 36Hz
to 38Hz, and highest recommended X-over frequency is 400Hz.
The SP7090 takes up the characteristics of the SP7010. Its cone is
treated on both sides thanks to a coating process designed and
developed in our R
&D Department which enables it to withstand
extremely severe outdoor conditions. Another advantage of such
a treatment is the decreasing of distortion by almost 6 dB.

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.
VENTED COMPACT MAGNET SYSTEM. It has been carefully 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 and vented 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.
