PHL Audio M17 Specifications

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.
DESIGN CONCEPT
PROGRESSIVE WAVE DIAPHRAGM optimized for midrange
frequency domain.
The M17/E17 Series design is based on the
mechanical behavior of the radiating area.
DIAPHRAGM
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.
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.
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.
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
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.
