5. Speaker Installation
To install S4-LCR Series modules, proceed as described in the
following paragraphs and Diagram 9:
Note:
Diagram 9 illustrates the installation of a S4-LCRMT module.
S4-LCR65W and multiple module installation is carried out in the
same manner.
• Having selected the installation positions and checked for the
presence of studs (joists), pipe work, ducts or cables, mark
cut-lines on the wall using the supplied template or templates.
Check that the dimensions of the cut-line are correct.
Note:
In order to reduce the possibility of audible wall vibration
it may be prudent to apply a bead of adhesive mastic between
the wall studs and the drywall (plasterboard) in the vicinity of wall
speakers.
Use an appropriate tool to cut along the cut-line to create a
cut-out in the wall. Trial fit the Installation Frame or frames in
the cut-out to check clearances.
With the cut-out checked, the Installation Frame or frames
can be installed. If frame flanges are required these should
be fitted at this stage. If the installation comprises multiple
S4-LCR modules, all installation frames should be fitted at
the same time.
To install an Installation Frame, insert the frame into the wall
cut-out and while holding it against the wall with one hand.
Use your other hand to turn four yellow securing clamps
outwards and slide them down securely against the inner
surface of the drywall (plasterboard).
Note:
If speaker cables are not already installed it should be done
at this stage. It is possible that access will be required through the
opposite side of the wall to route the cables. Use low resistance
speaker cable with clear polarity marking on its insulation. Low
resistance is especially important if the length of cable from
amplifier to speaker exceeds 5 m. Your local Dynaudio retailer or
distributor will be able to offer advice on speaker cable selection if
required.
• Pull the speaker cable through the appropriate Installation Frame
and wall cut-out. The length of free cable should be sufficient to
allow the Speaker Unit to be held in one hand while connecting
the cable to the speaker terminals with the other hand.

The speaker cable can now be connected to the Speaker
Unit. Strip 15 mm insulation from the cable (if necessary),
twist the wire strands and insert the stripped ends into the
speaker spring terminals. Ensure that the positive conductor
is connected to the red speaker terminal and the negative
conductor is connected to the black speaker terminal.
With the Speaker Unit connected to the speaker cable it
can be inserted into the Installation Frame. Turn the locking
tabs on the front surface of the Speaker Unit fully clockwise
(aligned with the lock icons) and insert it in the Installation
Frame. Push gently around each locking tab until a click
is heard. The Speaker Unit will then be secured in the
Installation Frame.
Note:
Take care that the cable is positioned in such a way that it will
not get trapped as the Speaker Unit is secured into the Installation
Frame and is not touching the Speaker Unit in such a manner that it
is likely to result in audible vibrations.
Note:
To remove a Speaker Unit from the Installation Frame turn
the locking tabs 90° counter-clockwise. Take care to support the
speaker as the locking tabs are turned.
Note:
The high frequency tonal balance of S4-LCRMT modules
can be adjusted to suit different installation environments. A
tweeter level switch located on the Speaker Unit front panel
2 dB and -1 dB options. The level adjustment operates
from approximately 3 kHz upwards. The +2 dB option may be
appropriate if, for example, carpets, soft furnishings and curtains
dominate in the listening environment. The -1 dB option may
be more suited to an environment where hard floors and glass
predominate.
• With speaker units connected and secured into in installation
frames, installation is completed by fitting grilles. Grilles are
secured magnetically and require no more than placing into
position.
Note:
If the wall is to be painted following speaker installation, the
supplied paint mask must be used to protect the speaker hardware
from paint ingress. Speaker grilles should not be fitted during wall
painting. They should be painted separately.
