PROFESSIONAL SERIES  
6.5” Midrange Driver  
High Efficiency  
Contact Class  
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.
