Elegant & Natural
The APart CMRQ108 is an elegant and very natural sounding in-wall/in-ceiling speaker.
It easily outperforms most standard cabinet speakers, both in sound quality and appearance.
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.
Due to the narrow visible mounting fl ange 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
fl atscreen TV.
Turn your living room walls into a wall of sound, at the highest possible hifi standards, exactly
there where you feel at home.
CMRQ108 has a 6.5’ bass-mid speaker with a DuPont® Kevlar cone and a low loss rubber
surround. This guarantees highest possible defi nition 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 commonly found in cheap metal
alloy domes. The treble contour can be adjusted in 3 steps to suit your personal preferences.
CMRQ108 is 8 ohms standard, and can easily be switched to 12 ohms. This way you can use two
speakers in parallel on one amplifi er channel, giving a total load impedance of 6 ohms. This load
impedance is standard for most surround receivers.
Mounting is easy and straightforward. The speaker clamps accept wall thickness of 0 to 28 mm.
By using our optional in-wall mounting frame, 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 CMRQ speakers are not magnetically shielded, this is not necessary unless you install them
close to a CRT screen. Flatscreens, the ideal partners for the CMRQ speakers, are insensitive to
magnetic fi elds. 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 applications

Recommended minimum installation volume: 7 liters. By using our optional in wall speaker
frame/cabinet, the optimum cabinet volume is guaranteed, however, 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 fi bre). Hard foam materials such as polystyrene and
other polyfoams are not suitable. Make sure the damping materials used meet all fi re 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 dust and small particles,
such as small stones because 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.
Impedance selection jumper located at
the rear of the speaker. Position the
jumper according to the required
impedance, 8 or 12 ohms.
The treble contour can be adjusted
in 3 steps to suit your personal
preferences
To make grille removal easier, a special grille removal tool is supplied with the speakers. Insert the
tool end in a grille hole located at the corner of the speaker 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 only, 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.
Speaker positioning
Mounting instructions
Impedance Treble contour
Ideally, you should position the speakers on ear level or above, never below, with the tweeter
on top. 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 refl ections and low frequencies,
causing an unstable stereo image and boomy bass.
If possible, mount the speakers close to the sides of your fl atscreen 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.
For hifi setups, mount the speakers between ½ and 2/3 of total wall height, for
walls up to 3 meters height, and stay at least 50 cm clear of adjacent walls and the ceiling.
If necessary, the speakers can also be positioned ‘lying on their side’, with the tweeters pointing
outwards, however, stereo image is more precise when mounting the speakers with the tweeters
pointing upwards. You can also mount the speakers in a ceiling if necessary.
