1. Introduction

The Tannoy T40 is a compact, versatile subwoofer system, primarily designed to
extend the low frequency response of the T12, i12 & i15 loudspeakers and increase
system headroom where required. The T40 will extend the frequency response of
these systems to below 40Hz and is capable of providing output levels which would
normally be associated with considerably larger enclosures. The compact dimensions
of the T40 enable it to be used in permanent or portable applications without being
obtrusive.

The T40 comprises one high efficiency 15”diameter/3”voice coil drive unit, and
features recessed carrying handles and a top-mounted stand socket which serves as
a base for locating the main full range or mid/high speakers in the air. By using
35mm tubing the need for a tripod stand can be eliminated. The cabinet is
constructed from multiple-ply hardwood which will survive the punishment that
speaker systems are subjected to on the road and in club installations.

The T40 has been designed to be used in conjunction with the Tannoy TX2 controller
for optimum performance. This provides specific crossover and equalisation
functions for the T12, i12, i15 & T40 combinations.

2. Unpacking

Every Tannoy T40 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 loudspeaker again requires packing
and shipping. In the event that damage has been sustained in transit notify your
dealer immediately.

3. Connectors/Cabling

The T40 is fitted with two 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 Speakon sockets identified as input/output on the rear of the input
panel are paralleled within the enclosure.

Tannoy have adopted the following wiring standard for the T40 :-

Pin 1+ is Positive
Pin 1- is Negative
