INSTALLATION
WARNING
If adding new speakers to an existing installation, or simply replacing old ones, you must ensure that the amplifier driving the system is
switched OFF.
WARNING
Prior to proceeding with the installation ensure that you determine the position of electrical cabling, pipe work and wall studs. Having
selected a wall location clear of any obstruction measure carefully to ensure the correct placement.
PAINTING
Before proceeding with the installation the grille and baffle panel can be painted to blend with the surrounding décor.
When painting the baffle be sure to carefully mask off the driver assemblies. It is important to ensure that paint does not come into
contact with the cone, roll surround or HF unit. Several thin coats of paint will provide a superior finish to that achieved by one applied
too thickly.
The speaker is supplied with a sheet of acoustically transparent protective foam fixed to the inside of the grille. Having painted the grille
to match the room décor please remove the original foam and replace with the spare sheet supplied in the accessory pack. It is important
that this replacement foam is bonded to the grille over it's entire area, using a suitable spray adhesive. Failure to do so will result in
audible resonace.
OVERVIEW
Tannoy In-wall loudspeakers have been designed for installation into standard stud partition wall systems constructed with 102mm by
51mm (4" by 2") timber at 406mm (16") centres. However, it is envisaged that they will generally be used in cavity wall installations
constructed with standard thickness plasterboard. These are guidelines and therefore do not preclude use of the Tannoy In-wall products
in different locations and a wide range of other wall construction types as long as they have a secure clamping surface up to maximum
thickness of 25.4mm (1").
Driver cone movement at low frequencies may become excessive unless steps are taken in the wall cavity void behind the loudspeaker to
provide a well sealed and accurately controlled rear 'enclosure' volume, this will effectively act as an 'enclosure' behind the speaker
(see Speaker Loading Volume section in this manual). Failure to ensure this will affect the bass and midrange performance unfavourably.
POSITIONING
There is a great deal of mounting location flexibility with both models when used in home cinema or multi channel systems. In particular,
please note that due to the unique point source symmetrical dispersion properties of the Tannoy Dual Concentric™ drive unit, the model
iw6TDC can be mounted in either portrait (in stud partition wall situations) or landscape positions where sufficient space exists behind
the wall surface.
To achieve the optimum spectral and stereo performance select your mounting location as follows:
Vertical plane
Align the front baffle centres at intended listening height, usually dictated by the normal seated listening position. For audio use, when
positioned in front of the listener, this will usually be in the range of 1100mm to 1700mm (43" to 67"). As home cinema rear effects
speakers mounted on the rear walls of the room, the mounting height range is 1530mm to 2140mm (60" to 84").
Horizontal plane
The loudspeakers should be located between 1500mm to 4500mm (60" to 180") apart – the room size and shape will dictate the final
mounting location, but generally the listening position, when used as a stereo pair, should be set slightly further away than the speakers
are apart.
Where the In-walls are used as rear effects speakers in a home cinema system the ideal viewing point will establish the distance from
the rear wall to the listening position. Avoid positioning the loudspeakers in corners of the room, as this will have a negative effect on
performance; maintain a distance of 1000mm (39") from a corner.
SPEAKER FITTING
REMEMBER.... MEASURE TWICE – CUT ONCE!
Once the mounting location has been selected use the template provided to mark out the area of wall material to be cut out. Carefully
remove the waste, checking again that there are no interferences from studs/wire/pipes etc.
Install the loudspeaker cabling ensuring that the wiring route is laid clear of all screws and nails that could potentially damage the cable
insulation. Allow sufficient cable length at the speaker end to allow for unrestricted connection.
It is necessary to block off the void behind the speaker by suitable means (insulation material or foam) to create an "enclosure" area.
This will offer the speaker the required loading volume as detailed in the specification section of this manual.
It is important to provide some acoustic damping between the speaker and the rear wall surface. We recommend use of a BAF sheet
(Bonded Acrylic Fibre). Ensure that materials used comply with local fire and building regulations.
