WARNING:
ALWAYS HOLD THE SPEAKER BY
THE PLASTIC SUPPORT, AVOIDING DAMAGE
TO THE TRANSDUCER DIAPHRAGMS
Step 5 – Screwing and fixing:
assembly to the ceiling, the tabs have to be
rotated and lowered. This is done by tightening the
corresponding screws clockwise. The first quarter
turn rotates the tab into position and out of the
guide; the rest tightens the tab down onto the
back of the ceiling surface. The process needs to
be repeated for all four screws.

screw the mounting tab comes down, pressing
the plastic support against the ceiling.

Step 6 – Replace the grille: once the speaker
is fixed to the ceiling, this is the only operation left.
Push the grille into place until fixed. You will
need to use the adhesives stripes provided.
Note: the grille shows some degree of
resistance to be removed. Fixing is by contact, so
there is little clearance between its inner diameter
and the inner support, so that some force needs
to be applied when removing it.
MAINTENANCE & USE
No maintenance is needed for the products in
this manual if they have been installed correctly
and following the instructions in this manual.
Some usage tips follow:
The best maintenance for a speaker is its
correct use, i.e., within the design parameters. It is
important not to utilise amplifiers that are too large
when compared to the speaker power. In general,
it is recommended that you use an amplifier with
an output that is 100% to 150% of the speaker's
average (RMS) power rating.
That way we have headroom for the dynamics
of real music and vocal signals, and at the same
time deliver a cleaner signal to the speakers that
will result in a more reliable system. Avoid using
too small an amplifier. The clip light of your
amplifiers should never be on continuously. This
will distort the signal and may damage the
speakers. In fact, severe clipping is an easy way to
burn a speaker's voice coil. At most, the clip light
could blink occasionally. When clipped, signals
sound distorted and produce listening fatigue
quickly. Never use a total impedance load that is
lower than the lowest impedance that an amplifier
will take.
Virtually all professional amplifiers will accept
loads down to four ohms safely in stereo mode.
Many are rated for two ohm loads but often will
run into overheating protection when used this
way, particularly in high ambient temperature and
high output power applications.
Never connect more speakers to an amplifier's
channel than it will take, i.e. do not load a channel
with total impedance that is lower than the
minimum load specified by the manufacturer.
