1. Introduction  
Designed for a wide variety of sound reinforcement applications the Tannoy i6 AW (All  
Weather) is an ultra compact loudspeaker system capable of delivering high sound  
pressure levels with extremely low distortion, resulting in outstanding clarity, definition  
and detail. A truly universal solution, the i6 AW offers outstanding durability and  
resistance to scuffs and knocks. Able to deliver consistent performance under a wide  
range of adverse conditions the i6 AW is suited to applications indoors or out, whether  
it be a theme bar or theme park. Available in dark grey or white the i6 AW will  
effectively blend into most backgrounds.  
Utilisation of the point source Dual Concentric loudspeaker allows the i6 AW to be  
mounted on a wall or ceiling in either horizontal or vertical orientations without  
affecting its performance. A range of hardware options ensures simple and effective  
installation. Also available with built in line transformer (i6T AW).  
The i6 AW comprises one 6.5 inch (165mm) 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. The sophisticated CAD designed waveguide combines 90 degree conical  
dispersion and excellent acoustic impedance characteristics.  
For applications requiring extended low frequency enhancement, a range of Tannoy  
sub-bass systems are available and can be used in conjunction with the i6 AW.  
2. Unpacking  
Every Tannoy i6 AW 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 i6AW has two 4mm binding posts 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 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:-

4. Polarity Checking  
It is most important to check the polarity of the wiring. 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 the red speaker terminal and likewise the -ve leg of the battery to the black speaker  
terminal  
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 of the  
loudspeaker to be realised.  
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  
compressor/limiter or active crossover is being used with multiple cabinets; it is  
therefore recommended that the same amplifiers be used throughout.

6. Power Selection (i6T AW)  
Determine the maximum power in watts needed at each speaker location. The i6 AW  
transformer can be tapped at 30w, 15w, 7.5w, & 3.75w via the rotary switch located on  
the metal plate at rear of the loudspeaker. When the relevant tappings have been  
selected add the individual wattages required at all speakers and select an amplifier  
with a rating equal to or exceeding the total wattage required. All of the transformer  
primaries should be connected in parallel to the output of this amplifier. If for example,  
you select the 7.5-watt transformer tap, it means that at full rated amplifier output the  
speaker will receive the full 7.5 watts. If the amplifier gain is reduced each speaker will  
receive a proportional amount of power, maintaining the overall system balance.  
When calculating amplifier wattage requirements for a system, it is recommended that  
a generous wattage safety margin (3dB of headroom) be left so that the system does  
not have to operate continuously at its full rated output  
7. Equalisation  
The i6AW loudspeaker is 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 i6AW loudspeaker is a point source, phase coherent  
design and violent equalisation will be detrimental to the overall sound quality.

9. Hardware  
The i6AW can be wall or ceiling mounted using the MB6 (optional) bracket (fig 1.)  
which is designed to offer the maximum flexibility in selecting the desired angles.  
The MB6 is supplied with M8 bolts for fixing to the loudspeaker (fig1.& 2). After fixing  
the bracket to the wall or ceiling remove the plastic plugs from the top and bottom of  
the loudspeaker. Position the cabinet at the required angle as shown and tighten the  
M8 Bolts to fix the loudspeaker in position.  
The loudspeaker can be mounted either horizontally or vertically using the MB6  
bracket (fig1.& 2.). This product has four M6 threaded holes in the rear of the cabinet  
for other bracketry.

12. Troubleshooting Guide  
Symptom  
Possible Cause  
Action  
No Output From Speakers  
Broken Speaker Cables(s)  
Check the electrical continuity of  
the loudspeaker cables, and  
replace if necessary.  
Amplifier  
Check the gain controls on the  
amplifier are turned up.  
Be sure the amplifier is receiving  
an input signal (check the  
“signal” indicators on the amp).  
Connect the loudspeaker cable  
which has no output to another  
amplifier channel you know is  
working, make sure signal is fed  
to the new amplifier channel. If  
output is obtained from the  
loudspeakers(s) then the  
problem is with the amplifier  
channel or input signal leads. If  
this is not the case then the fault  
may lie in the cabling or the  
loudspeaker.  
Intermittent Output  
Poor Connection  
Check the loudspeaker cabling  
has a good electrical connection  
with amplifier outputs and  
loudspeaker inputs. A bad  
connection can increase  
resistance which will substantially  
reduce the output, or make  
“cracking” noises which are  
unrelated to signal content  
If using multi-strand loudspeaker  
cable, be sure no strands of  
cable are causing short circuits  
between the positive and  
negative terminals of the  
amplifier outputs and/or  
loudspeaker inputs.  
Poor Low Frequency  
Output  
“Out of phase” connection  
When two speakers are  
connected “out of phase”, the low  
frequencies will virtually be  
cancelled out. Check the  
connections at the  
amplifier/speaker paying  
attention to polarity. (see section  
4).  
Irregular sounds such as  
buzzing and humming  
emanating from the  
loudspeaker  
Poor system grounding  
Check and correct system  
grounding.  
Faulty electronic device in  
the signal chain  
The speaker cannot generate  
these sounds on its own. It is  
most likely there is a fault with a  
piece of electronic equipment in  
the signal path.
