6.5" Midrange Driver
Very High Sound Pressure Level
High Sounding Quality
APPLICATIONS
These models are an excellent alternative to types SP1040/1050
when very high SPL are needed in sound reinforcement.
Sound transcription is of utmost accuracy due to the mastery of
the diaphragm behavior even at full level, which allows for their
use in studio monitoring too. Direct radiation within frequency
band 400Hz - 4000 Hz, in a sealed volume not exceeding 3L is
possible while use with a horn loaded for high power systems is its
real destination.
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. 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.
VENTED COMPACT MAGNET SYSTEM. Its has been carefully 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 and vented 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.
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.
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.
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 the operating life
duration is to be expected.
