1. Introduction
The Tannoy T12 and i12 professional loudspeakers have been designed for a wide variety of
sound reinforcement applications requiring extended frequency response from a compact system,
capable of delivering high sound pressure levels with extremely low distortion, resulting in
outstanding clarity, definition and detail.
The T12 and i12 comprises one 12 inch Dual Concentric driver in which the low frequency (LF)
and high frequency (HF) sources are coincidentally aligned to a point source, resulting in a smooth
uniform frequency response over a wide area of coverage either as a portable stand alone system
or in a multi-cabinet array. The sophisticated CAD designed waveguide combines 60 degree
conical dispersion and excellent acoustic impedance characteristics. As the system is a point
source, clusters and arrays have minimal lobing. These features are inherent and achieved
without the use of any electronic signal processing.
The T12 features a recessed carrying handle, stand mount and a rugged, multiple-ply hardwood
cabinet with structural integrity further enhanced by internal steel braces which double as the flying
points accepting M8 eyebolts strategically placed to distribute the weight of the enclosure evenly.
The T12 can also be used as a low profile stage monitor. Its conical coverage pattern gives the
performer greater freedom of movement than allowed by conventional horn loaded designs.
While delivering the same performance as the T12 and utilising the same transducer and high
power, low-loss crossover components the i12 is designed for fixed installations. Featuring the
same flying system as the T12 the i12 is constructed from medium density fibreboard (MDF), for a
high level of acoustic damping.
For applications requiring extended low frequency enhancement, a range of Tannoy sub-bass
systems are available and can be used in conjunction with the T12 and i12.
2. Unpacking
Every Tannoy T12 and i12 product is carefully inspected before packing. After unpacking your
loudspeaker, please inspect for any exterior physical damage, and save the carton and any
relevant packaging materials in case the loud speaker again requires packing and shipping. In the
event that damage has been sustained in transit notify your dealer immediately.
3. Connectors/Cabling
T12 and i12 are fitted with 4-pole Speakon connectors. Speakon has the following advantages
over EP and XLR type connectors: All termination’s are solderless, this makes life easier at the
time of installation or when field servicing is required. Contacts will accept 6 sq. mm wire with an
outside diameter of up to 15mm and a current rating of 30 Amps. The pins of the 2 Speakon
sockets identified input/output on the rear of the input panel are paralleled within the enclosure.
Tannoy have adopted the following wiring standard for the T12 and i12 products :-
Pin 1+ is Positive
Pin 1- is Negative
