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!
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.
tweeter ProteCtIon
The crossover networks are equipped with
an advanced electronic tweeter protection circuit
designed to minimize the possibility of tweeter
failure. This electronic device monitors current
going to the tweeter and will disconnect the
tweeter from the signal when it senses overload.
Should this occur while listening to the audio
system, simply reduce the volume for a few
seconds and the protection circuit will reset
itself automatically.
