1. Introduction
The Tannoy V12HP utilises a high performance Dual Concentric™ drive unit – the 12” (300mm)
PowerDual™. The substantially increased efficiency and power handling of this all-new driver design
ensures that the V12HP is capable of delivering high SPL’s in even the most demanding
applications. Like all Tannoy Dual Concentric loudspeakers the Tannoy V12HP exhibits true constant
directivity, providing an even frequency response over the entire area of coverage. The output
capability makes the Tannoy V12HP suitable for much larger audience sizes or venues requiring very
high SPL’s, such as nightclubs.
The V12HP comprises one 12inch PowerDual™ 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. 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 asymmetric cabinet profile allows flexible and discreet installation. As a foreground system,
installation is made simple with a range of Secur-ET mounting hardware, designed specifically for
the V series – or the system can be flown using the integral M10 inserts.
For portable stage use the birch ply cabinet has a recessed carrying handle on the rear of the
cabinet and a blanking plate, which can be removed to install an optional pole mount. As a
versatile low profile stage monitor, the conical coverage pattern gives the performer greater freedom
of movement than allowed by conventional horn loaded designs.
The V12HP has been designed for use with the Tannoy TX2 controller, which will equalise the system
resulting in improved bass performance as well as providing a 2-way crossover function, operating
at 100Hz, for use with separate sub-bass systems.
2. Unpacking
Every Tannoy V12HP product is carefully tested and inspected before being packaged and leaving
the factory. 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 V12HP is fitted with 4-pole Neutrik Speakon™ connectors. Speakon has the following
advantages over EP and XLR type connectors: All terminations 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 has adopted the conventional wiring standard for the V12HP product :-
Mode Of Operation
Speakon Pin No. Passive Full Range Bi - Amp
1+ Full Range + LF +
1- Full Range - LF 2+ No Connectors HF +
2- No Connectors HF -

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 sq. 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:-
CABLE RUN (m) C.S.A. OF EACH
10 2.5
25 2.5
50 2.5
100 2.5
4. Polarity Checking
It is most important to check the polarity of the wiring before the speaker system is flown. A simple
method of doing this without a pulse based polarity checker for LF units is as follows: Connect two
wires to the +ve and -ve terminals of a PP3 battery. Apply the wire which is connected to the +ve
terminal of the battery to the speaker cable leg which you believe to be connected to pin 1+ of the
speaker connector and likewise the -ve leg of the battery to pin 1-.
If you have wired it correctly the LF drive unit will move forward, indicating the wiring is correct. All
that remains now is to connect the +ve speaker lead to the +ve terminal on the amplifier and the ve lead to the -ve terminal on the amplifier. If however the LF driver moves backwards, the input
connections need to be inverted.
If problems are encountered, inspect the cable wiring in the first instance. It should also be noted
that different amplifier manufacturers utilise different pin configurations and polarity conventions, if
you are using amplifiers from more than one manufacturer, check the polarity at the amplifiers as
well as the loudspeakers.

5. Amplification & Power Handling
As with all professional loudspeaker systems, the power handling is a function of voice coil thermal
capacity. Care should be taken to avoid running the amplifier into clip (clipping is the end result of
overdriving any amplifier). Damage to the loudspeaker will be sustained if the amplifier is driven into
clip for any extended period of time. Headroom of at least 3dB should be allowed. When evaluating
an amplifier, it is important to take into account its behaviour under low impedance load conditions.
A loudspeaker system is highly reactive and with transient signals it can require more current than
the nominal impedance would indicate.
Generally a higher power amplifier running free of distortion will do less damage to the loudspeaker
than a lower power amplifier continually clipping. It is also worth remembering that a high powered
amplifier running at less than 90% of output power generally sounds a lot better than a lower power
amplifier running at 100%. An amplifier with insufficient drive capability will not allow the full
performance or the loudspeaker to be realised. (See technical specifications section for
recommended amplifier power)
It is important when using different manufacturers amplifiers in a single installation that the have
very closely matched gains, the variation should be less than +/- 0.5dB. This precaution is important
to the overall system balance when only a single active crossover is being used with multiple
cabinets; it is therefore recommended that the same amplifiers be used throughout.
6. Crossovers
The V12HP is supplied as standard for passive operation via the internal crossover network. If higher
peak outputs and additional low frequency output is required then the V12HP can be used in
conjunction with the Tannoy TX2 controller/crossover which provides high pass filtering and a
degree of parametric equalisation, as well as a fixed crossover point for use with sub-bass
loudspeakers (See the TX2 user manual for further information). The Tannoy TDX2 Digital controller
will also perform the above functions with additional control and features including limiting and
delay (See the relevant literature on the TDX2 for further information).
The V12HP can be easily configured for Biamp operation in conjunction with the TDX2 or other
OEM controller/crossovers. A detailed description along with system parameters is given in Section
13 of this manual.
7. Equalisation
The V12HP loudspeakers are designed to need no equalisation or correction to overcome system
limitations. As a result, it will only need equalisation to compensate for difficult acoustic
environments.
Over equalisation can reduce system headroom, and introduce phase distortion resulting in greater
problems than cures. If equalisation is required then it should be applied gently and smoothly. The
V12HP loudspeaker is a point source, phase coherent designs and violent equalisation will be
detrimental to the overall sound quality.
When a loudspeaker is used in close proximity to another, comb filtering effects can create coverage
problems, comb filtering creates an uneven frequency response across the coverage area due to
constructive and destructive interference effects between the sources. The amount of comb filtering is
affected by the spacing of the relative sound sources. Minimising this effect cannot be cured by
equalisation (see the following section for more details).
