To get best results from your new Tannoy Dimension loudspeakers it is worthwhile spending a little time finding the optimum
set-up configuration.
Begin by angling the speakers towards your chosen listening position, usually this is on the centre line of the room, so that
when seated you can just see the inner side panel of each speaker. The front of the loudspeaker should not be obstructed
in any way. The loudspeakers should be located between 1.5 to 4.5 metres (5ft to 15ft) apart - with the listening position
set slightly further away than the speakers are apart. Avoid positioning the loudspeakers in corners of the room, as this
will have a negative effect on performance. Ideally, maintain a distance of at least 0.5 metres (20 inches) from the rear
wall, and 1 metre (39 inches) from the side.
With the speaker in its listening position, rock the loudspeaker gently from side to side so that the spikes find their way through
the weave of the carpet and on to the solid surface below. Once fine adjustments have been made to the rear spikes, to
level the loudspeaker and ensure stability, tighten the lock nuts firmly but without using undue force.
POSITIONING AND FINE-TUNING
The Dimension grille has been designed to provide acoustic transparency. However, for ultimate fidelity the enthusiast will
appreciate the slight improvement in clarity and detail that is achieved by removing the grilles during listening.
SuperTweeter:
The mesh grille in front of the diaphragm is held in place by magnetism and may easily, but carefully, removed. It is essential
that the SuperTweeter diaphragm is not touched, as damage will destroy its performance and require specialist repair by
your Tannoy dealer.
Any such damage will not be covered under warranty.
Grille panel:
Provided in the accessory pack are six felt covered studs. These are designed to fit into the holes on the front baffle panel
once the main grille is removed. If the grille is to be refitted the studs should be removed and stored in the six holes provided
on the inside of the grille frame.
GRILLES
The accessory kit supplied with your Dimension speakers provides the materials necessary to maintain the high quality finish.
Wood surfaces:
The real wood veneer cabinets should only be cleaned with a dry cloth or with a light application of quality non-silicone
furniture polish. Take care not get polish on the velvet surfaces of the loudspeaker. It should be remembered that as a natural
substance all wood products will change colour when exposed to the UV content of ambient light. Light veneer will darken
appreciably to a rich natural patina.
Polished alloy surfaces:
The polished alloy side rails, cone feet and SuperTweeter housing should be polished using the polishing cloth provided.
Extra care is needed whilst polishing the SuperTweeter housing and it is recommended that the SuperTweeter protective grille
is in place so as to avoid damaging the diaphragm.
Velvet surfaces:
To remove dust from the velvet and smooth the pile of the velvet material use the non-scratch open weave side of the foam
pad, which is also to be found in the accessory kit.
CARE OF CABINET
(See figs. 2, 3 and 4)
To optimise performance further, use a shielded or screened loudspeaker cable. The screening termination should be connected
to the earth or ground (green) terminal on the loudspeaker and to the ground or earth connection on the amplifier. Alternatively
if you are not using a screened loudspeaker cable but wish to utilise the earthing facility, run a single cable between the earth
It is essential that the coupling link cables between the loudspeaker terminals be removed.
Avoid potential damage to your amplifier - ensure that all connections are secure and the polarity is correct in all wiring.
