PHL Audio E30 Specifications

12" Low Midrange Drivers
High Sound Pressure Level
High Sounding Quality
APPLICATIONS
Chosen preferably to types SP4550/4560 when higher AES Power
handling capacity is requested, these high SPL high sounding
quality low-midrange drivers are ideal for sound reinforcement
applications within the 60Hz to 2.0kHz frequency band , where
a pair can be used by paralleling two SP4060 for long throw
systems of exceptional sound accuracy. Maximum X-over
frequency is 1.5Khz in this case.
Optimum Bass-Reflex enclosure is 25L to maximum 40L tuned
from 53Hz to 60Hz.
DESIGN CONCEPT
DEFLECTION CONTROLLED DIAPHRAGM optimized for dynamic
damping.
DEFLECTION CONTROLLED DIAPHRAGM
in optimizing the shape and material of the diaphragm so that it
works as a mechanical transmission line, to avoid breaking modes
as well as mechanical threshold which destroy sound quality.
This leading edge technology offers substantial sonic advantages.
Among them: sound coherency, fast transients, stable sound
imaging, high sensitivity, wide frequency range and reduced
directivity pattern.
VENTED COMPACT MAGNET SYSTEM. It 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
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.
