cone is integrated into the custom-tooled foam
rubber surround, and right down to the magnet
protecting rubber boot - seamless and effective.
The five 'spokes' embossed into the cone extend
to the edge of the driver via a custom tooled foam
rubber surround. This surround offers excellent
damping and flexibility characteristics for great
sonic performance.
Rear-Vented Pole Piece
To prevent pressure from building up inside the
center cap and causing distortion and nonlin-
earities, a vent is provided on the rear of the pole
piece. This results in smooth cone movement,
which contributes to the smooth, powerful bass
response.
This vent also allows hot air to exit from the inside
of the voice coil and motor assembly. Heat is the
enemy of every speaker. Improved cooling means
that your subwoofer will play louder, longer.
S.E.T. - Spider Exhaust Technology
Adding to the arsenal of keeping things cool is
Spider Exhaust Technology. Five sets of cooling
vents, located on the basket between the magnet
and the spider provide a path for hot air to
escape from the voice coil. These vents also
release pressure from behind the spider, helping
to improve performance and reduce distorion.
Chrome-Plated Terminals
The speaker terminals are chrome-plated push-
on types with minimal contact resistance and
high current transmission efficiency.
Aluminum Voice Coil Former
Helping to dissipate heat and increase speak-
er longevity is an aluminum voice coil former.
Aluminum has excellent thermal conductivity
properties, which helps to wick heat away from
the copper voice coil windings.
Powerful Strontium Magnet
A high conductivity double-stacked magnet is
used in the SRW subwoofers to obtain an air-gap
magnetic flux density that is higher than conven-
tional ferrite magnets. Combining this magnet
with the heat-resistant voice coil results in sub-
woofers that are able to deliver high SPLs at large
inputs with improved damping.
Dual Spider Design
Keeping the cone under control during high
excursion levels is no easy task. The SRW
subwoofers have two independent spiders to
provide linear cone motion and excellent perfor-
mance.
SW Subwoofers
Providing performance at an unbeatable price are
the SW10X and SW12X subwoofers from Clarion.
These subwoofers feature many of the same
technologies as the SRW and PXW subwoof-
ers, including SET (Spider Exhaust Technology)
cooling, vented pole piece, Polypropylene dust
cap, Strontium Ferrite Magnets, Chrome Plated
Spring Terminals and a high temperature voice
coil former.
