Subwoofers – Technologies
A speaker that can better dissipate heat will
sound better and last longer. All Clarion subwoof-
ers feature SET (Spider Exhaust Technology)
cooling to allow heat generated from the voice
coil assembly to escape from the area beneath
the spider.
SET also allows pressurized air to escape from
beneath the spider. This improves overall speaker
linearity, especially at high excursion levels.
The PXW subwoofer allows hot air to escape
through the spokes of the basket. If you look
inside the basket, you can see that each spoke is
hollow. This extends to below the spider mount-
ing plateau, providing ventilation and cooling.
Dual Strontium Ferrite Magnets
There are many ways to alter the efficiency of a
speaker. The most common is to adjust the magnetic
field strength and the gap between the voice
coil and top plate. Clarion has implemented dual
high-quality Strontium Ferrite magnets in all PXW
subwoofers. This provides an intense magnetic field
for excellent efficiency, as well as controlled, dynamic
performance.
An additional benefit of this large motor structure is its
thermal mass. This helps dissipate heat from the voice
coil to further improve performance.
Hyper Extended Vented Pole Piece
The T-Yoke (Bottom plate) on all PXW subwoofers
feature a large cooling vent that is protected by a mesh
screen. This vent serves two purposes. It allows heated
air to escape from the inside of the voice coil and
allows pressurized air to escape from beneath the dust
cap. The mesh screen keeps debris out of the delicate,
narrow-gap voice coil gap area.
The bottom of the pole piece has been extended
to allow increased excursion capabilities from the
PXW subwoofers. Conventional designs result in
the voice coil bumping into the bottom plate.
Dual Gold Plated Terminal Blocks
A solid electrical connection is mandatory to
ensuring reliable speaker operation. The new PXW
subwoofers feature custom-tooled terminal blocks
that will secure up to an 8 AWG conductor. An
Allen-key is included with each driver to make
installation quick, easy and reliable.
Sewn Tinsel Leads
The connection between the voice coil and the
terminal block is critical, since all the power sent
to the speaker gets transferred through these con-
nections. The new PXW subwoofer feature mas-
sively oversized braided tinsel leads for excellent
power transfer.
To ensure silent and reliable operation, the tinsel
leads have been sewn to the spider at the bot-
tom of each roll. This allows the tinsel lead to flex
independently of the spider, preventing changes
in driver compliance at different volume levels.
This feature also allows the tinsel leads to operate
completely silently.
Linear Roll Poly-Cotton Spiders
Linear spiders offer extremely linear cone motion
control. This means that the new Clarion PXW
subwoofers will sound good while operating at low
levels and remain controlled and dynamic when
being pushed to high excursions.
