iW Series

Quick Start Guide

Positioning

There is a great deal of mounting location flexibility with these 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 iW4 DC and iW 6DS 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 the 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 height range of 1100 mm to 1700 mm (43" to 67"). For use as home cinema rear effects speakers mounted on the rear walls of the

room, the mounting height range is 1530 mm to 2140 mm (60" to 84").

Horizontal plane

The loudspeakers should be located between 1500 mm to 4500 mm (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.
When 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 1 m (39") away from a corner.

Speaker Fitting

Remember .... Measure twice - cut once!
1. 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.

2. 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 an unrestricted connection.

3. 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.

4. 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 all materials used comply

with local fire and building regulations.

5. Strip 8 mm (1/4 inch) of shielding from the end of the speaker cables in preparation for connection to

the terminals on the rear of speaker.

6. Check that the clamping arms are aligned as shown prior to insertion in the wall.
7. Connect the speaker cable observing the correct wiring polarity. The positive terminal (

and coloured red) should receive the positive cable (usually marked with a repeated stamped name,

line or raised rib) and the negative terminal (marked - and coloured black) the negative cable.

8. Insert the baffle into the pre-prepared hole in the wall, ensuring that the speaker wire is located

securely away from the driver, as contact with the driver cone will cause annoying buzzes.

9. Each of the clamp screws can now be tightened (clockwise). Starting at one corner then move to the

opposite corner, tightening sufficiently to check for visual orientation, before proceeding to tighten

the other two corners.

10. Finish off by tightening the middle clamps.

WARNING

: Do not over tighten the screws - this is unnecessary to achieve a strong acoustic seal to

the wall, and risks damaging the wall surface
11. Repeat the installation procedure for the other loudspeakers and complete the connection process

to the amplifier.

12. Once again ensure that correct cable polarity is observed.
13. Switch on the amplifier with the volume control at its lowest setting. Select a signal source and

slowly turn up the volume to a low level. Check that bass and treble information comes from both

speakers - if not, switch off the amplifier and recheck the connections.

14. Carefully check the area surrounding the installation and ensure that there are no buzzes or rattles

that could potentially impair enjoyment of the system. If there are, then locate and silence the

causes using cable ties or suitable packing material.

15. Optimum performance will be assisted by the use of silicone sealant to seal gaps between the studs

and the wallboard material. This cavity sealing will help to create a near airtight seal. Do not silicone

the baffle to the wall as the clamping mechanism creates an effective bond.

Grille Fitting and Removal

The grille should be carefully fitted to the front baffle aperture, by lining up the edges of the grille carefully with

the baffle. To avoid indentation damage, do not press the centre of the grille; apply even pressure to the corner

as it is pressed firmly into position.
To remove the grille, loop an opened paper clip or similar length of firm wire, through two holes near a corner

and pull gently. The grille is intended to be a tight fit, so insert the wire at each corner in turn, pulling carefully to

avoid distortion of the mesh.

Speaker Loading Volume

There are two simple approaches to achieve a sealed 'enclosure' to provide the correct driver loading area behind

the speaker.
The chosen method will depend on whether the wall is under construction, as in a new building project,

or an existing wall where access is limited.

Option 1

Stud partition walls under construction, with 102 mm by 51 mm (4 by 2 inch) timber at 406 mm (16 inch) centres.
1. Block off the cavity, above and below the intended speaker opening, with the same framing timber.

The distance between these two internal barriers should be as shown in this table:

Model

Distance

iw4 DC

410 mm (16")

iW 6DS

550 mm (21.5")

iW 62DS

825 mm (32.5")

iW 62S

825 mm (32.5")
