PHL Audio 7510 - Manual

B46
APPLICATIONS
Dedicated to Sub-Bass applications when high power handling
is not specified, these drivers are able to cover a wide frequency
band, ranging from 30Hz to 500Hz with remarkable sonic
properties (even considering directivity pattern) that allow them
to be used in a three-way Sound Reinforcement system as well as
in a specific Sub system of medium input power.
The recommended enclosure is a Reflex type with volume ranging
from 200L to 250L tuned from 38Hz to 40 Hz.

DESIGN CONCEPT
DEFLECTION CONTROLLED DIAPHRAGM optimized for dynamic
damping. DEFLECTION CONTROLLED DIAPHRAGM technology
consists 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 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.
