LED Equipped Models: Integrated Transflective™ RGB
LED lighting system (patent-pending) delivers smooth,
even accent illumination, with no hot spots. LED
functionality requires separate wiring at each speaker
location. Adjustable control of RGB lighting requires the
use of an RGB lighting controller (sold separately). For
optimal per formance, we recommend using the
JL Audio marine lighting controller (MLC-RW).
While these speakers are designed to be water
and spray resistant, they are not designed to be
submerged or to withstand high-pressure water
spray. Please exercise care when washing your
boat to avoid damaging your speakers. Do not
install on submersibles, personal watercraft or any
other vessel likely to be under water at any time.
Prolonged exposure to sound pressure levels in
excess of 100dB can cause permanent hearing
loss. This high-performance speaker can
exceed this level. Please exercise restraint in its
operation in order to preserve your ability to
enjoy its fidelity.
When installing speakers in your vessel, it is
extremely important to secure them firmly. This
applies not only to the speakers themselves,
but also any structure they are mounted to. If
not firmly attached, the speakers can become
dangerous projectiles in a collision. Please
review the mounting information carefully and
use the supplied marine-grade hardware to
mount this product.
It is absolutely vital that your coaxial speaker
system is connected as shown in this manual.
Failure to connect the system as shown will
result in damage to your speakers which
is NOT covered under warranty. Do not
substitute different crossover networks.
Do not attempt to remove the tweeter from
the bridge (Sport) or the grille (Classic). Do
not attempt to remove the lighting LEDs from
from the speaker. The tweeter and LEDs are
permanently fixed and attempting to remove
them will cause damage and this damage will
not be covered under warranty.
