INTRODUCTION
The lightning ash with arrowhead symbol within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated "dangerous voltage " within the
product's enclosure that may be of sucient magnitude
to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the product.
Thank you for selecting Tannoy loudspeakers developed in the UK by our dedicated team of
design engineers. They are the choice of discriminating music lovers the world over. Musical
excellence is designed into our loudspeakers from the start. Careful selection of the very best
components combined with strict quality control procedures in the production process ensures
this level of excellence is maintained. To gain maximum performance and for safety reasons,
please take time to read this installation guide in full before tting.
The Mercury ceiling loudspeakers use a high quality coaxial bass driver and tweeter
conguration. This gives an even spread of sound as you move away from the central axis,
maintaining the uniformity of the frequency response.
Loudspeakers are electromechanical devices that ‘run-in’ through use; performance will
therefore improve after an initial period of 24 hrs use. Once they have been further run-in
over a longer period, there will be clear enhancement of imaging, mid-band quality and bass
performance characteristics.
We are condent that you will continue to enjoy your new Tannoy Mercury ceiling loudspeakers
for many years to come.
CAUTION
• Ensure there are no supporting joists, electric cables, water or gas pipes that could be cut
during installation.
• Do not attempt to install these loudspeakers unless you are certain of providing a safe
and secure xing.
• Always work from secure steps, and avoid trailing wires that could provide a trip hazard.
• Ensure your amplier is switched off before beginning any wiring or connections.
IF IN ANY DOUBT, CONTACT YOUR LOCAL AUTHORISED TANNOY DEALER.
BEFORE BEGINNING WORK, NOTE THAT THE MINIMUM RECESS DEPTH FROM THE
MOUNTING SURFACE IS 68 mm, (2.7”) FOR THE IC5 & 77 mm (3”) FOR THE IC6 MODEL.
THESE LOUDSPEAKERS CAN ONLY BE INSTALLED INTO A PLASTERBOARD (DRY-LINED)
OR SUSPENDED CEILING HAVING A THICKNESS OF UP TO 40 mm (1.5”)
PAINTING
If desired, the grille and bafe may be painted to match the surrounding décor before
installation.
• BAFFLE: Carefully mask off the driver assembly with the paint mask provided. Use several
thin coats of paint to give a better nish than one overly thick coat.
• GRILLE: Likewise, several thin coats of paint should preferably be used.
• Allow the paint to fully harden before proceeding.

polarity, positive - red, negative - black.
2. Using a keyhole saw, cut out the hole in the
ceiling by following the dotted line outlined
on the cutout template.
4 Slide the loudspeaker assembly through the
hole, and turn the screws to extend the
mounting wings. To avoid damage, do not hold
the loudspealer by the tweeter assembly.
