The Quest Engineering MW Series
High-Performance In-Wall Speakers are the
ideal choice for supplying high-fi delity sound
without the need to use any fl oor or shelf space.
Designed to work right out of the box and into
the wall, the Quest MW Series provide Dynamic
Balance components and aim-able tweeters to
ensure amazing clarity, spacious imaging and
a well-balanced sound in any listening position
The MW series can also be painted to match any
decor blending with your environment to provide
nothing but high-performance sound.
Your Quest Engineering MW Series In-Wall
Speakers can provide you with nearly
endless placement options. Please take in to
consideration your placement options prior to
installation, as an installation requires holes to be
If you are unsure about the correct way to install
or the best way to place your in-wall speakers
please consult a professional audio installation
You can fi ll a room with sound by installing
in-wall speakers in nearly any wall or ceiling
location. Quest MW Series In-Wall Loudspeakers
have a wide dispersion pattern, allowing you to
focus their sound accordingly.
You can improve the imaging and detail your
Quest MW Series In-Wall Speakers provide by
aiming the tweeter toward your listening position.
When using the MW Series as front/main home
theatre speakers, aim the tweeter toward your
chosen listening position.
For rear/surround speakers installed in walls
or ceilings, aim the tweeter toward the nearest
refl ecting wall, such as an adjacent wall or
ceiling, for a more diffused sound fi eld. If you
prefer a more direct sound, simply aim the
tweeters toward your listening position.
To adjust the tweeters, do so by holding the
edges of the tweeter carefully between the
thumbs and forefi ngers of both hands, then rock
the tweeter slightly to aim it toward the desired
Quest MW Series In-Wall Speakers are
magnetically shielded and should not be
placed closer than 30 cm from a television or
video monitor. If you experience discolouration or
distortion on your display, immediately move the
speakers away from your television or monitor.
When you install your Quest MW Series In-
Wall Loudspeakers, make sure you are aware
of the weight of your particular model (see
specifi cations page 11 for the weight of your
particular model) and the sturdiness of the
material into which you are installing the speaker.
Also be aware of any concealed studs, electrical
wiring or plumbing in the wall into which you are
installing the speakers. If unsure of a safe way
to install these speakers, consult a professional
installer, your authorised Quest Engineering
Dealer, or a building contractor.
If you plan to install your MW Series speakers
where they may be in direct contact with water,
it is advisable to use a silicone sealant or caulk
between the frame of the speaker and the wall
surface. This seal should prevent water from
getting behind the loudspeaker and possibly
damaging the wall surface. Do not position the
speaker where water can pool on the surface
of the woofer cone or tweeter dome, as this will
greatly decrease the speaker’s useful life.
Preparation is the key to a tidy and successful
installation and performance. For best bass
response the speaker baffl e should be as close
as possible to an airtight seal, so no vibrating
air from the back of the box can leak through
to the front. “Whistles” and poor bass response
will be the result of poor installation. Time spent
carefully measuring and cutting wall and ceiling
surfaces will save patch up time later. Also
clearly establish that there is suffi cient depth in
wall and ceiling cavities to accommodate the
speaker. With correct installation and wiring
to rigid and airtight surfaces, your MW series
speaker will deliver sonic results normally
associated with top-end hi-fi delity transducers.
Another important point is to make sure you have
enough amplifi er power for the job intended.
A 100 watt speaker driven by a distorting 20
watt amplifi er will not realise the speaker’s full
potential. A low powered amplifi er delivering
signal through long distances of very thin wire
will not give the best results. For long speaker
cable runs, 1.5 – 2.5 mm cable is better.
Matching amplifi er power to the speaker load will
also deliver clarity at higher dB levels and is safer

Steps to Installation Success
• Ensure the material into which you intend
to mount the speakers – plaster, dry wall,
panelling, stone, etc. – can support the weight
of the speakers (refer to specifi cation page for
the weight of your product).
• This is an important point! Make sure the
locations you select do not conceal studs,
electrical wiring or plumbing. Prior to
installation, hold the speaker in your chosen
location to make sure it clears obstacles such
as studs, corners, beams, lighting fi xtures and
door/window frames. Your cutout must be at
least 25 mm from adjoining walls or ceiling,
internal studs or plumbing.
