1. Introduction
Thank you for purchasing Tannoy PowerDual™ iQ 10/15
As part of the HDSR
TM
product group, the iQ range is the next generation of high
intelligibility sound reinforcement loudspeakers from Tannoy. High Definition Sound
Reinforcement (HDSR
TM
) products specifically designed to provide high intelligibility
audio reproduction in such locations as houses of worship, performing arts centres,
auditoria, stadiums and larger music venues; in fact, any public space where high
performance, high definition sound can enhance the listening experience.
Using a 250mm (10”) version of Tannoy’s own unique, point source and constant
directivity PowerDual™ driver, the iQ 10/15 is a single cabinet full range system
incorporating a 15” horn loaded bass driver. This high efficiency bass driver,
functioning from 43Hz to 180kHz, has been optimally designed to acoustically match
the iQ10 HF/MF section to deliver high definition sound reinforcement at low
frequencies. This is mounted in the lower section of the enclosure and is horn-loaded
to deliver increased efficiency and improved LF output.
The HF/MF section, covering a frequency range from 180Hz to 18kHz, uses the
amalgamation of the exceptional PowerDual™ driver with the Funktion One Research
patented Axhead™ horn technology to provide a controlled 60° horizontal and 40°
vertical dispersion pattern. Exclusively this unique combination incorporates the High
Frequency element of the PowerDual™ into the Axhead™ phase plug itself; providing
not only a point source time coherent design, but a valuable reduction in overall size
as no separate HF horn is necessary as in other ‘phase plug’ designs
This compact high power sound reinforcement solution is ideal for live or fixed
installation music and speech sound reinforcement applications. The construction of
the cabinet is exceptionally robust, using 18mm birch plywood throughout, and is
equipped with carrying handles, extensive rigging and pull back points in order to
facilitate the use of various flying options. A full-length foam-covered powder coated
perforated steel grille is provided. The trapezoid angles of the enclosure facilitate the
creation of optimized-coverage arrays.
The system may be installed in the standard LF and passive HF/MF bi-amp
configuration or alternatively, as an option, set up in fully tri-amp mode.
Comprehensive system control may be provided by the addition of the TannoyTDX1
or TDX2 digital loudspeaker management systems.
2. Unpacking
Every Tannoy iQ10/15 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 10/15 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 the iQ 10/15: -
SPEAKON™
CONNECTOR
SIGNAL
Pin 1+ LF Positive
Pin 1- LF Negative
Pin 2+ MF/HF Positive
Pin 2- MF/HF Negative
For a worldwide list of Neutrik distributors see
http://www.neutrik.com/
*A custom termination panel is available for tri-amp operation
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 10/15 has been designed to operate in conjunction
with the Tannoy TDX1 & TDX2 System Controllers, and iQ18B 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
patterns of each loudspeaker combine with minimal overlap. The design of the
iQ 10/15 cabinet greatly simplifies the creation of effective arrays, allowing seamless
wide (120 degree) horizontal coverage using two loudspeakers wit hout the need for
tedious experimentation.
By placing the iQ 10/15 cabinets as shown in the diagram below, minimal dispersion
pattern overlap is achieved, guaranteeing an extraordinarily smooth transition.

SECUR ET – VEB Eyebolt
!
The Tannoy iQ 10/15 loudspeaker can be flown
with high quality VEB M10 eyebolts with collar to
BS4278:1984. The loudspeakers are equipped
with internal steel braces, which also double as
the flying points, and accept VEB M10 eyebolts.
To install the VEB M10 eyebolts remove the
original M10 counter sunk screws from the
locations you wish to install the VEB M10
eyebolts. Then replace these counter sunk M10
screws with the VEB M10 eyebolts. The kelping
brackets on the rear of the cabinet should only
be used for tilting the loudspeaker to the desired
angle.
Important: It is imperative for safety reasons
that two eyebolts linked to two independently
fixed straps are used per cabinet.
Never attempt to use formed eyebolts i.e.
formed from a steel rod and bent into an eye.

12. System Configurations & OEM Controllers
Passive or Biamp?
The iQ 10/15 is supplied as standard for bi-amp operation, therefore there is no
internal passive crossover network between the LF & Mid/High units. The Bi-amp
controller parameters below must be adhered to for optimum performance.
An optional iQ 10/15 (tri-amp version) can be ordered.
A loudspeaker driven in Bi-amp mode offers a number of performance advantages,
such as increased system headroom. Audio program materiel is made up of many
different frequencies and harmonics. In music materiel, most of the energy is in the
low frequencies, with less in the highs. When both high and low frequencies are
present in a signal, the stronger low frequencies can use up amp power, leaving little
or no reserve for the highs, so they are more likely to cause the power amplifier to
clip. In a Biamp driven system, a smaller amp can handle high frequencies, LF amp
clipping is less of a factor, and less overall amplifier capacity is needed due to the
efficiency improvement in the absence of a passive crossover.
