1. Introduction
This manual describes the installation of S4-LCR Series modules
within drywall/plasterboard walls. It begins by listing the carton
contents and continues information specific to installing in-wall
speakers.
If this is your first time working with Dynaudio Studio Series
custom install speakers, or if you have not done so for a while, we
recommend that you read the appropriate sections of this manual
before you begin.

information.
The S4-LCR Series is designed to provide very high quality left,
centre, and right channel audio in custom installations where
speakers are required to be fitted flush in walls. The S4-LCR Series
not only benefits from four decades of Dynaudio speaker expertise
but has been designed through its modular format to offer enhanced
versatility in terms of both practical installation and acoustic
performance.
S4-LCR Series modules comprise a Speaker Unit and Installation
Frame. The Installation Frame is inserted into the wall cut-out and
securely fixed in place using auto-locking clamps. The Speaker Unit
is then connected to the speaker cables before being inserted into
the Installation Frame to be held in place by a latch system. The grille
is then fitted, secured by magnets integrated within the Installation
Frame.
• S4-LCR Series modules are uniquely simple to install. Once a
wall cut-out is created, no tools are required and installation can
be completed by one person without assistance. Every element
of the S4-LCR Series installation procedure, from unpacking the
speakers to painting and fitting the magnetic grilles is simplified
and streamlined by design.
• S4-LCR Series speakers employ numerous Dynaudio
technologies, borrowed from the company’s studio monitors and
high-end hi-fi speakers, to bring genuinely high performance
audio to custom installations: unique bass/mid drivers with large
diameter aluminium voice coils and finite element optimised, low-
distortion magnet systems, proprietary MSP (Magnesium Silicate
Polymer) diaphragms, and precision coated soft dome tweeters
with powerful neodymium magnets are just a few examples
among many.
• The S4-LCR Series comprises two modules:
the S4-LCRMT mid/tweeter module and the S4-LCR65W twin
driver bass module. A single S4-LCRMT module can be used
with one or, for higher volume level applications, two S4-LCR65W
modules.
• S4-LCRMT sensitivity can be adjusted via a rear mounted switch
to match either one or two S4-LCR65W modules. The electrical
crossover between S4-LCRMT and S4-LCR65W modules can
be accomplished passively, using either the standard internal
passive filters, or actively using external active filter components.
Switches and bypass jumpers located on the rear of the speaker
units engage or bypass the internal passive bass module low
pass and mid/tweeter high pass filters.
1.1 Carton Contents
The carton contents for all S4-LCR Series modules are essentially the
same. Items only differ in terms of format and dimension. Within each
carton can be found:
1 x Speaker Module
1 x Installation Frame
2 x Frame Flange
1 x Cut-out Template
1 x Paint Mask
1 x Document pack
A typical carton contents is illustrated in Diagram 1.

S4-LCRMT
• Each S4-LCR Series module is supplied with a pair of Installation
Frame Flanges. With frame flanges fitted, modules can be
installed individually and spaced apart. With one or both frame
flanges removed, multiple modules can be consolidated and
installed in a common wall cut-out.
• S4-LCRMT modules are intended to be installed only in portrait
orientation, however S4-LCRMT speaker units can be rotated
within their installation frames in order that the frames match the
orientation of adjacent S4-LCR65W modules.
• S4-LCR65W modules can be installed in either landscape or
portrait format. In either case, multiple modules can be either
consolidated for installation in a common wall cut-out, or installed
in individual wall cut-outs.
Grilles are not supplied with S4-LCR Series modules but can be
supplied as accessories in a range of lengths to suit installation
configurations. S4-LCR grilles attach magnetically and fully paintable.
