Please read this manual carefully before using the product. This will give you the
necessary product and installation instructions to assure a seamless installation and
non compromised overall sound quality.
Thanks for purchasing our APart CMSQ108 speaker. We have put great care and
effort in the design in order to bring you high quality sound. The CMSQ108 is an
elegant and very natural sounding in-wall/in-ceiling speaker. It easily outperforms
many standard cabinet speakers, both in sound quality and appearance.
CMSQ108 has a nominal impedance of 8Ω, allowing you to connect up to 2
speakers in parallel per 4Ω stable amplifier channel. Easy to integrate in high-end
audio chains, cinema surround systems or even high quality BGM systems, this
speaker offers a soundstage, unheard in this price range.
Introduction
• Keep this manual for future reference.
•When making the hole in your mounting panel to mount the APart CMSQ108
speaker, make sure there is sufficient clearance behind the panel (no
obstructions like A/C channels, power lines etc).
•Take care of your speaker wires, they should be free of damage. Damaged
speaker wires might result in poor sound quality and can damage amplifiers.
•Only use accessories specified by the manufacturer
•Make sure the mounting panel can support the speakers weight.
•Use sufficient amount of speakers to avoid death-spots.
•No mains power shall be connected to the loudspeakers, doing so will damage
the speaker.
•This apparatus should only be serviced by qualified personnel. If not warranty

might be void.
•Use cable of the right gauge, certainly for long runs.
•Use cables with clear color indication and maintain polarity throughout the
whole system.
•Avoid loud feedback from microphones, this can damage your speaker.
•Please check the units condition after unpacking. If the outside of the carton
box has been damaged, inform your shipper immediately.
• Take notice that this speaker is meant for indoor use only!
Turn your living room walls into a wall of sound, at the highest possible hifi
standards, exactly there where you feel at home. CMSQ108 features a 5.5” bass-
mid speaker with a paper/Kevlar sandwich cone and a low loss rubber surround.
This guarantees highest possible definition and lowest sound coloration. High
frequencies are covered by a tiltable 1 inch silk dome tweeter, carefully matched
and tuned to deliver an amazing and detailed sound without the harshness usually
reproduced by cheap metal alloy domes.
Due to the narrow visible mounting flange and paintable detachable steel grilles,
the speakers can be integrated very discretely in even the most demanding
environments, in your living room, connected to your multiroom system, hifi or
cinema surround audio system… side by side to your flatscreen TV.
Mounting is easy and straightforward. The speaker clamps accept wall thickness
of 0 to 30 mm. By using our optional in-wall mounting cabinet, you can install the
speaker even in solid brick walls. Speaker cables are securely clamped in the gold
plated cable connectors, accepting thick speaker cables up to 6 mm².
The CMSQ speakers are not magnetically shielded, this is not necessary unless you

Recommended applications
Ideally, you should position the speakers on ear level or above, never below. When
the speakers are positioned far above the listening position (more than 60 cm),
pivot the tweeter and aim it towards the listening position.
Avoid the presence of wall corners, because these will augment reflections, causing
an unstable stereo image and boomy bass.
If possible, mount the speakers close to the sides of your flatscreen TV, about 1.5
meters or more apart from each other, depending on screen size and listening
distance. In general, the listening position and the left and right speaker should
form an equilateral triangle and the speaker should be positioned halfway the
screen or slightly higher.
Speaker positioning
install them close to a CRT screen. Flatscreens, the ideal partners for the CMSQ
speakers, are insensitive to magnetic fields. Instead we have invested in solid
gold plated speaker wire terminals, a carefully tuned crossover with high quality
components, solid steel speaker grille and of course top notch quality drivers. You
will hear the difference!

Recommended minimum installation volume is 4 liters. By using our optional in
wall speaker frame/cabinet, the optimum cabinet volume is guaranteed. There is
no upper volume limit. When the speaker is installed in a space with hard materials
such as bricks or concrete, additional cavity damping may be required. Suitable
materials are mineral insulation materials such as Rockwool or BAF (bonded
acetate fiber). Hard foam materials such as polystyrene and other polyfoams are
not suitable. Make sure that the used damping materials meet your local fire and
building requirements. Check that there are no obstacles such as electrical tubes,
wires or other pipes behind the speaker. Make sure the area behind the speaker is
free of small particles such as small stones. These particles can damage the vented
magnet system of the speaker. In cases of doubt, protect the rear of the speaker
with a small amount of BAF wadding.
To make grille removal easier, a special grille removal tool is supplied with the
speakers. Insert the tool in a corner of the grille and gently pull the grille out.
Repeat this step on all corners until the grille is entirely free. Do not attempt to pull
out the grille by pulling one side of the grille, this may cause damage to the grille
or the frame. Keep the tool at hand in case you need to remove the grille.
Be extra careful when positioning the tweeter: do not touch the tweeters membrane.
Keep the tilt angle within a range of 10 degrees from the neutral position.
Speaker mounting instructions
For hifi setups, mount the speakers between 1/2 and 2/3 of total wall height, for
walls up to 3 meters height, and stay at least 50 cm clear of adjacent walls. You
can also mount the speakers in a ceiling if necessary.

Note: when making the hole in your mounting panel, double check if there are no
cables or any other obstructions behind the mounting panel. Cutting the mounting
panel without this check might result in damaged infrastructure or power lines.

The CMS5BBI built-in box
Because we want to make the lives of installers easy APart offers a built-in box for
our square CMSQ108 speaker. The box is insulated to prevent resonance and is
custom-built. Once again, APart proves to be your one stop solution for all your
installed sound projects!

Use the correct polarity when daisy chaining speakers! When a mistake occurs
in your daisy chain, it can severely impact speaker performance as there will be
audio-cancellation.
The daisy chain options are endless and the setup will depend on the capabilities of
your amplifier. Make sure when daisy chaining speakers that the total impedance is
not lower than the lowest specified impedance of your amplifier. Not following this
rule might result in distorted sound and might even damage your amplifier.
