APPLICATIONS
Derived from midrange drivers SP1500/1510, these 1”entry horn
coaxial versions are dedicated to sound reinforcement applications
when a compact Mid-High radiating source is required.
Their ability to keep sound accuracy at high SPL is well appreciated,
together with the fact that any 1”exit HF compression chamber can
easily be fitted, acoustically as well as mechanically.
A sealed volume not exceeding 3L is strongly recommended while
horn loaded for high power systems is a real possibility.
FEATURES
DESIGN CONCEPT
PROGRESSIVE WAVE DIAPHRAGM optimized for low-midrange frequency domain.
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.

This leading edge technology offers substantial sonic advantages.
Among them coherent sound, fast transients, stable sound imaging, high sensitivity,
wide frequency range and reduced directivity pattern.
ARCHITECTURAL SPECIFICATIONS
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.
NOMINAL DIAMETER : 166 mm.
FRAME : High tensile alloy pressure die-cast
basket with patented INTERCOOLER
SYSTEM.
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.
MAGNET SYSTEM :2”highly energized, heat
extracting design with flux stabilizing ring
and pole piece incorporating
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.
concentric horn flare.
FERROFLUID COOLING The FERROFLUID COOLING Proceeding consists in replacing
the voice-coil air clearance in the air-gap by a stable magnetic fluid which offers
far better thermal conductivity, allowing the driver to withstand an extra amount of
power of short to medium duration with less risk of coil overheating than in
the unferrofluid design.
VOICE COIL : High-temperature stabilized,
FERROFLUID®-cooled copper-clad
aluminum ribbon wound on
high-strength glass polyimide former.
Improving short term reliability, the main advantage of FERROFLUID COOLING is its
thermal compression reducing effect which can reach 3dB at high power.
Nevertheless, no improvement of operating life duration is to be expected.
CONE ASSEMBLY : High-strength cellulose
fiber cone impregnated and coated on
both sides with damped resins, fitted
with acoustically transparent dust cap
and high-speed flat damped surround.
COAXIAL SYSTEM The PHL AUDIO COAXIAL SYSTEM Concept is based on a horn
which is formed by the cone profile and the pole piece extension of the LF driver.
The 1”horn entry is situated in the axis of the rear side of the magnet system.
The front access to the LF driver voice-coil is protected against dust by an
acoustically transparent dust-cap. Coaxial drivers are always delivered with a
compression driver standard mounting plate, screws and a 1”O ring sealing gasket.
SPEAKER MASS : 2.60 Kg.
