1. Introduction
Thank You for purchasing Tannoy PowerDual™ iQ 10.
The iQ 10 has been designed for live and fixed installation music and speech sound
reinforcement applications. They are specifically designed for use in venues,
theatres, arenas and distributed systems in stadiums. The iQ 10 can be used both
indoors and out due to its durable “skeletonised” plastic weatherproof enclosure.
The iQ 10 utilises a point source 10” PowerDual™ driver utilising the unique Funktion
One Research engineered and patented Axhead™ technology, which provides a
controlled 60° × 40° (H × V) dispersion, covering a frequency range from 180Hz to
18kHz. For low frequencies, the iQ 10 has been designed to operate in conjunction
with the iQ 18B sub-woofer, where overall system balance is achieved by using the
TDX1 or TDX2 system controller, with provision for the relevant cross-over
frequencies, delays, gains, high and low pass filters and parametric EQ amongst
other features.
Tannoy’s, iQ 10 is a weatherproof skeletal design suitable for use both indoors and
out, where the compact and lightweight unit allows for flying into tight corners. The iQ
10 has two Speakon™ connectors for ease of installation. An optional plywood
cabinet is also available to match the iQ 18B profile where they can be flown together
using additional hardware for flying.
The iQ10 comes in 4 variants:iQ 10 - Skeletal iQ 10 Configured for Bi amp operation.
iQ 10P - Skeletal iQ 10 with internal passive crossover.
iQ 10C - iQ 10 Configured for Bi am p operation in plywood cabinet.
iQ 10PC - iQ 10 with internal passive crossover in plywood cabinet.
2. Unpacking
Every Tannoy iQ10 is carefully tested and inspected before packing. After unpacking,
please inspect your iQ10 for any damage sustained during transit. In the unlikely
event of any damage, would you please notify your dealer immediately and retain
your shipping carton, as your dealer may ask the faulty unit to be returned for
inspection.
3. Connectors/Cabling
The iQ 10 is fitted with two 4-pole Speakon™ connectors. Speakon™ has the
following advantages over EP and XLR type connectors: All terminations are
solderless, making 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 15 mm
and a current rating of 30 Amps.
The pins of the Speakon™ sockets, marked input/output on the rear of the speaker,
are paralleled within the enclosure.
Tannoy has adopted the following wiring standard for iQ 10: -

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. 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 they 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.
5. Operation
For optimal performance, the iQ 10 has been designed to operate in conjunction with
the Tannoy TDX1 & TDX2 System Controllers, and iQ 18B bass unit for extended
bass performance. The TDX controllers have been factory preset to provide the
recommended eq, crossover points, and overall system balance. Please refer to the
TDX1 & TDX2 manual for operation.
If you intend using an alternative loudspeaker management system (e.g. BSS™,
KlarkTeknik™, XTA™ etc) please refer to section 12 of this manual.

6. Equalisation
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. Violent equalisation will be detrimental to the overall
sound quality.
7. Arraying
Comb filtering is a phenomenon, which cannot be cured by equalisation. Small
alterations to loudspeaker positions can have the effect of minimising problematic
combing frequencies. Arrays should be constructed so that the individual coverage
patters of each loudspeaker combine with minimal overlap. The design of the iQ 10C
cabinet greatly simplifies the creation of effective arrays, allowing seamless wide (120
degree) horizontal coverage using two loudspeakers without the need for tedious
experimentation.
By placing the iQ 10C cabinets as shown in the diagram below, minimal dispersion
pattern overlap is achieved, guaranteeing an extraordinarily smooth transition.
It is also possible to stack the cabinets vertically using the above method, say for use
in a central cluster, where greater vertical dispersion is required.
