APPLICATIONS
The main purpose of these models is sound reinforcement direct
radiation multi-way systems when the low freq. extension required
does not allow types SP1040/1050 to operate in good conditions.
Designed with higher Xmax capability types SP1060/1070 can be
X-overed from as low as 400 Hz when single or 300 Hz when used in
pairs, and will then exhibit all their sound quality potential.
FEATURES
DESIGN CONCEPT
Power handling capacity 130 W AES
PROGRESSIVE WAVE DIAPHRAGM optimized for low-midrange
Reference efficiency(1W @ 1m) 97 dB SPL
extended frequency domain.
SPL max (continuous)
Usable frequency range 300-6000 Hz
Environmental withstanding Outdoor
114 dB SPL
The M17/E17 Series design is based on the PROGRESSIVE WAVE
DIAPHRAGM mechanical behavior of the radiating area.
In this principle, the membrane is considered as a mechanical
transmission line which should receive a constant given velocity
together with critical damping properties to work properly.
ARCHITECTURAL SPECIFICATIONS
This leading edge technology offers substantial sonic advantages.
Among them : very low mechanical energy storage in the cone
(so avoiding standing waves) which ensures coherent sound, fast
transients, stable sound imaging, high sensitivity, wide frequency
range and very-low directivity pattern.
NOMINAL DIAMETER :166 mm.
FRAME : High tensile alloy pressure
die-cast basket with patented
INTERCOOLER SYSTEM.
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.
MAGNET SYSTEM : 1.5”highly energized,
heat extracting design with flux
stabilizing ring.
VOICE COIL : High-temperature
stabilized copper-clad aluminum
ribbon wound on vented,
Its design incorporates a T-shaped pole piece, and a flux
stabilization ring. It also takes into consideration demagnetization
at cold temperatures.
high-strength glass polyimide.
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.
CONE ASSEMBLY : High-strength cellulose
fiber cone impregnated and
front-coated with damped resins, fitted
with fabric dome and high-speed flat
damped surround.
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.
SPEAKER MASS : 2.15 Kg.
