BACKBOX IN-WALL LOUDSPEAKERS
Introduction
M&K Sound backbox in-wall speaker systems are designed for easy installation.
You are just a few easy steps away from enjoying the acclaimed M&K sound.

• Damping pads, cable fittings, and push terminal connectors for quick install
• Dog screw mounting system with self-locking clamps for solid attachment to wall
• Metal front grille and front baffle with integrated magnets for easy grille mounting
Placement
For placement of M&K Sound in wall speakers, please note the following basic
recommendations for installation.
Defining correct
placement height
for M&K speakers in
stereo or surround
set-up is essential,
beginning with
finding the speak-
er’s acoustic on axis
point, marked
between woofers
and tweeters as
shown below.
• For both stereo and surround front speakers the system’s acoustic “on axis-point” should be approximately 10-
15 cm above ear level – when sitting in listening position.
• For surround rear and side speakers the systems acoustic “on axis-point” should be approximately 70-90 cm
above ear level – when sitting in listening position.
• Every new M&K Sound In-Wall speaker is designed to be as universal as possible, whether used in In-Wall and/
or In-Ceiling applications. The range is fully compatible with all current and future sound formats, including
Dolby Atmos, DTS X and Auro. For specific directions of any speaker placement, we recommend to study the indi-
vidual formats own instruction manuals.

IW300 and IW150
Using IW300 and IW150 with acoustically transparent
screen, it is recommended to position left and right speak-
ers with tweeters pointing inward towards the screen and
place center speaker in vertical position behind the screen.
When using IW300 and IW150 with a non-transparent screen, the center channel can be placed above or below
the screen, while the Left and Right speakers may be moved up or down, to approach the vertical placed center
channel position. (Fig A)
If the center channel is placed horizontally, place the tweeters closest to the screen. (Fig B)
IW950
When using IW950 with a transparent screen, placement on
a center line with tweeters aimed downward at the listening
position is recommended.
When using IW950 with a non-transparent screen, the center channel can be placed horizontally above or below
the screen, while the Left and Right speakers may be moved up or down to approach the horizontally placed
center channel position.
Left / Center / Right Orientation
In a typical front speaker configuration, the M&K models are recommended to be used as shown below.
Stereo Orientation
The above recommendations are to be followed for any stereo application. A good formula when setting up a stereo
system, is to have the same distance between left and right speaker to the listening position.

Speaker Installation
To support precise wall cut-out for M&K Sound backboxed speakers, use the template included in the carton.
The 2-piece carton template matches the speaker’s outer dimensions, with a “push out” section is to be used for
the actual cutting.
Following the instructions 1 - 8 will result in proper and easy installation of the speaker.
1. Use the overall carton template to visualize wall
position for system, before pushing out the actual
cutting template at the perforated lines.
2. Hold the “pushed out” cutting template at the wall
to mark a line for the actual cut.
3. Cut to the inside of your marked line on the wall. 4. Cutting direct on the template is not recommended

5. Connect the speaker to cables in the wall, and place
cabinet into “the wall cut”.
6. When speaker is placed into “the waa cut”, turn
the Torx screws on the front clockwise to activate the
mounting clamps.
7. Check if speaker is perfectly aligned 8. Mount and align the grille,
- and your installation is done!
Important Practical Information!
When using an electric tool for screw mounting, adjust the tension function to prevent the dog screws from
being over-tightened. It is also recommended to use moderate or low speed when tightening the dog screws.
If removal of speaker is needed for service, make sure to loosen the front dog screws slowly until you can feel
some resistance.
At this point, the mounting clamps should be turned back to neutral position and speakers are ready to be pulled
out of the wall cut.

Speaker Connection
Use the solid push terminals for easy speaker wiring to amplifier for cables up to 5 mm / AWG 6.
In surround system setup, it is important to wire all speakers correctly for correct phase.
It is therefore recommended to use speaker cable with marked wires for + and – leads for an easy visual check of
the connection.
