1. Introduction
Introducing the Tannoy i7 Contour infinite baffle installation loudspeaker, designed for
use in applications requiring high quality music and speech where wide, yet controlled,
coverage is needed.
The i7 Contour comprises four 4-inch (mm) low frequency (LF) drivers and one high
frequency (HF) unit. The LF and HF sources are placed in an array, resulting in a wide
horizontal dispersion and narrow vertical dispersion. These are combined with a smooth
uniform frequency response and excellent acoustic impedance characteristics.
With its slim-line cabinet the i7 Contour's shallow profile allows discreet vertical or
horizontal mounting close to a wall or ceiling and is available in dark grey or white to
effectively blend into most backgrounds. Utilisation of the dispersion characteristics
(110 70 ) of the loudspeaker allows the i7 Contour to be used in highly reverberant
environments, by directing the sound into the desired space whilst minimising
reflections from adjacent walls or ceilings. An optional mounting bracket ensures simple
and effective installation.
Also available with a built in THP 60 low insertion loss transformer the i7T Contour
provides a more dynamic performance with greater bandwidth than other 70/100V line
systems.
For applications requiring extended low frequency enhancement, a range of Tannoy
sub-bass systems are available and can be used in conjunction with the i7 Contour.
2. Unpacking
Every Tannoy i7 Contour product is carefully inspected before packing. After unpacking
your loudspeakers, please inspect for any exterior physical damage, and save the
carton and any relevant packaging materials in case the loudspeaker again requires
packing and shipping. In the event that damage has been sustained in transit notify your
dealer immediately.
3. Connectors/Cabling
The i7 Contour has two screw terminals for connection to the amplifier, these are gold-
plated in order to improve electrical conductivity and to prevent oxidisation. These
terminals are capable of accepting cables with a conductor diameter of up to 6mm.
Red is Positive
Black is Negative
Cable choice consists mainly of selecting the correct cross sectional area in relation to
the cable length and the load impedance. A small cross sectional area would increase
the cables' series resistance, inducing power loss and response variations (damping
factor).

Connectors should be wired with a minimum of 2.5 mm
(12 gauge) cable. This will be
perfectly satisfactory under normal conditions. In the case of very long cable runs the
wire size should exceed this, refer to the following table for guidance:-
