APPLICATIONS
Built according to PHL AUDIO Quality standards, this rugged
Contact Class model is ideal for improved replacement
of sound reinforcement industry standard types, bringing low
harmonic distortion as well as long term reliability to the design.
FEATURES
DESIGN CONCEPT
PROGRESSIVE WAVE DIAPHRAGM optimized for midrange
frequency domain.
The M17/E17 Series design is based on the PROGRESSIVE WAVE
DIAPHRAGM mechanical behavior of the radiating area.
Power handling capacity 160 W AES
Reference efficiency(1W @ 1m) 98 dB SPL
SPL max (continuous)
116 dB SPL
Usable frequency range 500-6000 Hz
Environmental withstanding Outdoor
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 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.
VOICE COIL : High-temperature
stabilized copper wire wound on
vented, high-strength glass
polyimide former.
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.
CONE ASSEMBLY : High-strength
cellulose fiber cone impregnated and
front-coated with damped resins
and 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.
