de-ionized water. This recreates a condition of
100% humidity. Clarion products subjected to
these tests must pass without corrosion, damage
or failure.
ASTM D4329 - UV Exposure Testing
This testing standard describes an evaluation
of the damaging effects of long term outdoor
UV exposure. The test subjects must withstand
alternating cycles of 8 hours of ultraviolet light
exposure at 70 degrees Celsius, followed by 4
hours of condensation at 50 degrees Celsuis,
then repeated for extended periods of time
in multiples of 500 hours per test (up to 2000
hours). The devices under test must pass without
discoloring, fading, chalking or cracking.
Centrex 814 and BASF Luran 778T
Chassis' and Grills
Clarion marine speaker chassis' and grills are
injection molded from a polymer plastic called
Centrex 814. Our new Quality Series Marine
speakers are formed from BASF Luran for additional
resistance to thermal abuse. These plastics have
physical properties similar to ABS plastic, but
adds the ability to resist chalking, fading and
yellowing due to prolonged UV exposure.
Triple Gasket Design
All Clarion marine speakers include a synthetic
rubber mounting gasket to ensure water does not
infiltrate behind the speaker. This not only protects
the speaker itself from damage, but the hull of
the boat. All marine speakers feature Santoprene
rubber surround at the outer edge of the woofers
for durability and flexibility in all weather conditions.
Coaxial marine speakers feature a custom tooled
Santoprene rubber gasket at the base of the
woofer cone that seals the cone to the tweeter
mounting post. These three gaskets ensure there
is no way water can penetrate the speaker,
causing it to fail or your boat to be damaged.
Integrated Water Management System
Clarion Marine speakers are not only designed
not to allow any water to penetrate into the motor
mechanism of the driver, but they include a water
drainage channel to allow any water that gets in
behind the grill to drain out. This helps to ensure
that the speaker always sounds great, even when
being pelted by rain or washed down while in
dock.
7-inch speakers
Clarion's line of 7-inch diameter speakers set
new standards for marine audio entertainment.
These speakers were designed to the same strict
tolerances as our 6.5-inch speakers, but offer
improved efficiency, as well as improved bass
output thanks to a 35% increase in cone area.
The results of our efforts is a speaker that is 3dB
more efficient with dramatically improved low
frequency extension and smooth band to band
performance.
Performance Series Speakers
The new Performance Series of marine speakers
were developed to meet the needs of demanding
enthusiasts. The line includes a 6.5" coaxial, a 7"
coaxial, a 3-way 6"x9" and a pair of subwoofers -
one 8-inchs in diameter and the other 10-inches.
These speakers (where applicable) feature a
1-inch PEI dome tweeter for excellent reliability
