introduction

The Stratospherix is a high quality in-ceiling
loudspeaker featuring a semi enclosed back­box. It employs a large 200mm (8”) bass
driver with concentric professional grade
compression tweeter, for high power handling
and sensitivity. The dual concentric driver
confi guration guarantees uniform sound
coverage in all directions. The bass driver
features a weather-proof polypropylene cone,
whilst the compression tweeter is protected
by an acoustically transparent dust cap. To
ensure reliable performance both indoors
and outdoors the grille is made of corrosion
resistant aluminium and all other hardware is
stainless steel.

applications

The weather-proof design of the
Stratospherix, combined with high power
handling, sensitivity and extended bass
performance, make it ideally suited to outdoor
in-ceiling applications. For example, it can be
used in undercover alfresco dinning areas,
courtyards or near swimming pools. The
Stratospherix may also be used for indoor
applications requiring high volume levels, for
example larger concealed home cinemas.

before you begin

Please read the disclaimer on the back

!

of this manual.

After discussion with your local Krix •
distributor, or installation consultant,
determine the best location for your
loudspeakers. Check for any obstructions,
such as electrical wiring, plumbing, stud
work or air conditioning ducts before
commencing the installation. (fi gure 1)
Also check that there is enough ceiling
depth to accommodate the speaker
enclosure.

Care should be taken to ensure that

!

the ceiling material is strong enough to
support the product weight. Structural
materials such as plaster board, cement
sheet and wood are generally suitable.
Non-structural ceiling materials, such as
fi bre mat suspended ceiling tiles are NOT
suitable without additional reinforcement.

connecting

To ensure optimum performance it is
important that your speaker system is
connected properly:

Turn off all electronic equipment and

!

disconnect from the power point.

Follow the connection instructions •
supplied with your amplifi er, CD/DVD, hard
disk recorder, video player etc.

• Install speaker cable in wall or ceiling
cavity, or run cable along wall surface.
Allow approximately 300mm of excess
cable to facilitate loudspeaker installation.

• Follow the connection instructions
supplied with your amplifi er to connect
the speaker cables to amplifi er. Take care
to assign the same cable colour or trace to
the positive (+) connector on the amplifi er
as the positive (+) connector on the
speaker.

• Prepare speaker cables for connecting to
speakers by neatly stripping cable ends.

Care should be taken to eliminate loose

!

strands of wire that may present a short
circuit hazard.

installation

Once the correct speaker placement has •
been determined, use the cardboard insert
marked ‘template’ (from the internal
packing) to trace the required cut-out onto
the ceiling/wall. (fi gure 2)

Drill a hole inside the marked cut-out. •
Using a fi ne plasterboard saw cut around
the inside of the marked cut-out.
(fi gure 3)

Remove the circular offcut and insert the •
speaker to check the hole is the correct
size. Enlarge the cut-out if required.

To install the speaker, fi rst remove the •
grille. To remove the speaker grille use
the mounting clamps located around the
edge of the enclosure. Swing the mounting
clamps out so that they are 90 degrees to
the enclosure, and gently push upwards
evenly on the clamps until the grille lifts.
Carefully lift out the grille without bending.
(fi gure 4)

Pull the stripped speaker cable through the •
ceiling/wall opening. Push and hold down
the positive (+) red binding post on the
speaker and insert the positive (+) wire
through the hole in the post. Take care to
assign the same cable colour or trace to
the positive (+) connector on the amplifi er
as the positive (+) connector on the
speaker. Repeat connection process with
the negative (-) black binding post and
the negative (-) wire. (fi gure 5)

Ensure all mounting clamps are swung •
back against the speaker enclosure
(fi gure 5), so that the speaker can be
easily inserted into the ceiling cut-out.
Once the speaker has been located in
the ceiling/wall, use a Phillips head
screwdriver to tighten all mounting
screws. Be careful not to over tighten
screws, as this may strip the clamp,
or crush the plaster board surface. As
the screws are tightened, the mounting
clamps will automatically swing out over
the plaster board and clamp the speaker in
place. (fi gure 6)

If painting the grille and speaker frame is •
not required, gently fi t the metal grille to
the front of the speaker housing.
(fi gure 7)

If the grille and speaker frame require •
painting, ensure the black front baffl e
is masked off to protect the speaker
drivers. When painting the metal grille it is
recommended to use a small foam roller
and it may necessary to thin down the
paint to avoiding blocking the holes in the
grille. After all paint is dry, fi t the grille to
the front of the speaker housing.
