Product Summary
The TQ-440SP is a com pact three-way self-powered full range enclosure including integral power
am plifiers and control electronics. The use of active power am plifier technology ensures an exact
m atch between am plifier and speaker for optim um acoustic output, and offers exceptional ease of
use by com bining the entire electro-acoustic system in one convenient, easily transportable
physical package.
It incorporates a custom -designed co-axial 12"/1" com bination LF/HF driver in an optim ally tuned
vented trapezoidal enclosure handling the low and high frequency bands. The critical m id-range
frequencies are handled by a proprietary 6.5" cone transducer on a 60° horizontal by 40° vertical
nom inal disperion waveguide, loaded with a TurboMid device.
The exclusive use of cone transducers in both the low and m id frequency bands produces a
seam less transition at the crossover frequency, with the result that all of the critical vocal range
right up to 8kHz is lower in distortion than com pression driver-based designs. In addition the 6.5"
m id-range driver is a highly efficient device, and is able to handle large am ounts of am plifier
power. The rem aining high frequencies above 8kHz are effortlessly handled by a 1" com pression
driver, operating in a relatively narrow pass band, and therefore subjected to m inim al m echanical
stress. The m id and high com ponents are physically tim e aligned within the enclosure, ensuring
perfect tim e arrival at the listener's ear. When com pared to conventional two-way designs the TQ-
440SP is able to offer higher SPL, significantly lower distortion, and unsurpassed vocal projection
capabilities in an equivalently sized physical package.
A rear panel switch selects optim ised profiles for speech or m usic applications, enabling real
flexibility of use.
The TQ-440SP is a full range loudspeaker, and used by itself will provide high quality audio for all
speech and m any m usic reproduction applications. In order to extend the effective bass frequency
range of the loudspeaker by a further octave the use of the com plem entary TQ-425SP subwoofer is
recom m ended.

System Requirements
The TQ-440SP is a self-powered loudspeaker system . It com prises two independent am plifier
channels: one channel to power the low frequency driver (LF) plus another channel to power the
m idrange (MF) and high frequency (HF) together; and a frequency dividing network to split the
signal and feed it to the appropriate driver section. Additional features such as accurate and
optim ised peak lim iters for both high and low frequency sections are incorporated into the control
electronics. The TQ-440SP does not require the use of external am plifiers or crossover/lim iters.
Additional TQ-440SP units m ay be daisy-chained together sim ply by linking the signal connections
throught the input / link XLR connectors. In this way exact coverage of an event or perm anent
installation m ay be achieved using a num ber of self-powered loudspeakers. It is however
necessary to route individual power cords to each enclosure as it is not possible to daisy chain
through the power connectors.
AC power requirements
The TQ-440SP is equipped with a Neutrik Powercon AC m ains connector, which m ates with the
power cord supplied with your unit. The TQ-440SP operates with m ains voltages either in the
range from 100 to 120 volts a.c. or from 220 to 240 volts a.c. The m ains voltage on your unit will
have been preset at the factory prior to shipm ent. However for clarification please check that both
the product and the power cord m atch the m ains supply available in your area before use.
Should it be necessary to alter the m ains voltage setting, for exam ple when touring a country with
m ains voltage supply differing from that of the country of original shipm ent, the m ains voltage
switch is located on the inside of the am plifier m odule adjacent to the m ains transform er. Follow
the instructions given in the Maintenance section of this m anual for rem oval of the am plifier
m odule, and change the voltage setting to m atch the available supply.
The m ains fuse is a 3.15A 20m m anti-surge type for 230v m ains supplies, and 6.3A 20m m anti-
surge type for 115v m ains supplies. Should it ever be necessary, always replace the fuse with the
identical size and type.
Power Amplifiers
The TQ-440SP is equipped with two high power am plifiers designed with sufficient headroom to
handle large signal transients without break up or distortion, in contrast to other self-powered
designs which attem pt to com prom ise using inadequately powered am plifiers. The LF am plifier
delivers 250 watts r.m .s., while the MF/HF am plifier delivers 150 watts r.m .s.

Audio Input
The signal input to the TQ-440SP is fully balanced, with an input im pedance of 10kΩ. The input
XLR connector is wired pin 2 hot (+ve), pin 3 cold (-ve), and pin 1 screen (shield). The link XLR
connector is wired pin 2 hot (+ve), pin 3 cold (-ve), and pin 1 not connected. Multiple TQ-440SP
enclosures m ay be driven from a single audio console, up to a practical lim it of 16 units. Any m ore
will cause unacceptable signal loss due to the loading of the console output.
Limiting Functions
The TQ-440SP is equipped with accurate peak lim iters for both high frequency and low frequency
sections. Because the HF and LF lim iters work independently of each other, there is no possibility
of either section com prom ising the perform ance of the other as is the case with a single broad-
band lim iter. Furtherm ore, each lim iter has its attack and release tim e constants independently set
and optim ised according to the operating frequency range.
Music / Speech Optimisation
A rear panel switch m odifies the overall response of the TQ-440SP in order to give you optim ised
profiles for different applications. When the speech position is selected, the response of the
system will exhibit a reduced low frequency / low m idrange content, which has the effect of
m aking the upper part of the frequency range m ore prom inent. This results in exceptionally good
intelligibility, and therefore the speech setting is recom m ended whenever m axim um voice
projection is required. Additionally, under m ost circum stances the speech setting will provide
higher perceived m axim um sound pressure level.
When the m usic position is selected, the low frequency section is extended down to a nom inal cut-
off frequency of 55Hz, which m akes the TQ-440SP balanced for full range reproduction of a wide
range of m usic. The low frequency extension is achieved by using a com bination of a 2nd order
high-pass filter and a dynam ic EQ section, with the following benefits:
♦
♦
Frequencies below 50Hz are attenuated, and the m echanical stress on the low frequency drive
unit is therefore m aintained within safe lim its.
The use of dynam ic as well as than fixed EQ reduces the loss of headroom on large signals.

QLight series
Equalisation
Because the TQ-440SP features a sm ooth and even frequency response, it does not need
equalisation or correction to overcom e the deficiencies often found in lesser designs.
Should extended frequency response be required at m ore than m edium sound pressure levels, the
use of the com plem entary TQ-425SP self-powered subwoofer is strongly recom m ended
In order to com pensate for the room acoustics, the TQ-440SP requires only m inim al equalisation.
As in any system , over-equalisation introduces phase shifts, distortion and a reduction in
headroom , usually causing m ore problem s than it cures.
Under m ost circum stances a 1/3 or 1/2 octave graphic equaliser will generally be adequate, with
the fader settings applied sm oothly and as little as possible for the required room com pensation.
Most room s will have resonances that will be excited at particular frequencies needing som e cut to
help tam e the sound, these problem s are m ost pronounced at the lower frequencies where
speakers generally exhibit very little directional control.
If you find that the system needs a lot of boost at lower frequencies you m ay need additional sub-
bass units as stated above. It is good practice to use as little equalisation as possible, aim ing to cut
frequencies rather than adding large am ounts of boost.
Dispersion
One of the design features of the TQ-440SP is its tightly controlled 60º horizontal by 40º vertical
nom inal dispersion pattern at m id and high frequencies. This gives m any user advantages and
eases placem ent decisions, being essentially a point and shoot system . A 60º horizontal polar
pattern equals an angle of 30º either side of the centre line at which the sound pressure level is
6dB down with respect to centre, (averaged over the whole frequency range of the loudspeaker).
Thus a 40º vertical dispersion gives an angle of 20º above and below the horizon.
Cooling
The TQ-440SP am plifiers are norm ally cooled by the action of convection from the large heatsink
m ounted externally to the am plifier m odule at the rear of the enclosure. It is im portant to leave
sufficient space around and especially above the heatsink to allow the convection of heat away
from the loudspeaker. Under the m ajority of circum stances this cooling effect is sufficient to
m aintain the am plifiers within a norm al operating tem perature range. In conditions of high
am bient tem perature and/or in very confined spaces, the use of an external fan m odule is
recom m ended. A 24 volt socket is provided on the rear panel for that purpose.

Mounting and Fixing
A versatile range of m ounting hardware is available for the TQ-440SP that allows it to be used in a
variety of ways, in either m obile applications or perm anent installations.
A top hat stand type fitting is m ounted in the base of the cabinet
for use with 35m m diam eter loudspeaker stands with a load rating
of at least 37kgs (82lbs).
This top hat fitting m ay also be used to m ount the TQ-440SP
cabinet at the correct height above the com plem entary TQ-425SP
subwoofer using a straight 35m m pole.
Internal m etric threaded rigging points are provided
in several locations on the cabinet – on the top, bottom
and sides - enabling it to be flown using standard M10
shoulder eyebolts (available from Turbosound).
Downward inclination of the enclosure can be adjusted
using an additional rigging point on the rear of the
cabinet.
Side-m ounted flying strips can be fitted to the sides of
the enclosure by rem oving the countersunk bolts on
the top and sides of the cabinet and replacing them
with the M10 bolts provided with the hardware. Two
FF-440 flying strips are required for each enclosure.
This m ethod offers a sim ple and cost effective m ethod
of flying single or m ultiple TQ-440SP enclosures, with
the load being taken through the steel strips rather
than through the woodwork of the enclosure.
Enclosures m ay be arranged in a vertical colum n by
coupling the flying strips together using QL-75
quicklinks or shackles.

The universal FB-12 flybar assem bly enables the use of
several different fixing m ethods, shown in the diagram here.
The flybar is attached to to the cabinet using a pair of captive
M10 shoulder eyebolts (supplied). There are 12 attachm ent
points equally spaced along the length of the spine.
Depending on which point is chosen for the given attachm ent
system , a wide range of downward inclination can be achieved
over a range of approxim ately 70 degrees. The design of the
flybar even allows for upwards angles, for exam ple for
coverage of balconies that are higher than the loudspeaker
location.
The FB-12 flybar assem bly com es supplied with a U-6 Unilock which provides a single attachm ent
point. The point at which the Unilock is attached to the flybar determ ines the vertical angle of the
loudspeaker as shown in the table following.
A PP-440 pick-up point adaptor offers a further single attachm ent point. This option provides fast
adjustm ent of vertical angle. The point at which the eyebolt adaptor is attached to the flybar
determ ines the vertical angle of the loudspeaker as shown in the table following.
The SC-440 alum inium scaffold clam p adaptor is attached to the T-bar by m eans of a sim ple
clevis coupler. It is designed to rotate horizontally through 360° in order to enable accurate

Modular flybar assem bly The key elem ent in flying
m ultiple TQ-440SP enclosures is a versatile Flying
Bar Assem bly (FB-58), m anufactured by
Turbosound, that will support a vertical colum n of
up to three enclosures deep. Fly bars can be linked
in the horizontal plane using the index pins
provided to form arched arrays with adjustable
(horizontal) angles from 0º to 45º at 5º increm ents
per cabinet. This allows arrays and clusters of
alm ost any angle to be configured with the ability
to change array angles without dism antling and
whilst suspended. This useful feature allows for
fine tuning of speaker positions for best coverage,
throw and SPL’s.
On each side of the TQ-440SP cabinet you will find
keyhole type quick-release flying plates, plus top
and bottom rear brackets for pull-up straps and
linking plates. Single cabinets are suspended with
short fixed length steel cables (FS-40) and pull up
straps (TS-440) to align the downward angle. When
flying m ore than one cabinet in the vertical plane
the second row of speakers is flown on longer
fixed length steel cables (FS-61).
Any installation, whether tem porary or perm anent, m ust be securely attached to the structure of
the building using chain, steel wires or web straps which are certified and load rated for the
purpose. The com bined weight of the sound system , its cables and the rigging system m ust be
safely carried by the points at which attachm ent is m ade to the building or structure. Great care
m ust be taken in selecting the attachm ent points and m ethods, being absolutely sure of the load
carrying capacity of points chosen.
NOTE: The rigging of loudspeaker system s is an extrem ely serious m atter with potentially lethal
consequences should anything go wrong. It is of vital im portance that you, or other people rigging
the system , are suitably qualified to do so and have a full understanding of all the factors involved
with safety as a num ber one priority. Turbosound accepts no responsibility for any accident,
dam age or failure of any rigged system . This rigging inform ation is specifically related to the
requirem ents of the TQ-440SP only. For m ore detailed inform ation on the whole topic of rigging
various handbooks are available. If you are in any doubt contact your Turbosound dealer who will
be able to refer you to an experienced rigging com pany.

Arraying
The TQ-440SP has a side-wall angle of 16º. Use this position for sm ooth horizontal dispersion that
is ideal for m any applications. With the high dynam ic range capability and low power com pression
of the TQ-440SP you should find this wide angle arrangem ent adequate for all but the m ost
dem anding long throw requirem ents. It also has the advantage of needing fewer cabinets to cover
the required area.
When speakers are m ounted together in close proxim ity either stacked on top of each other or
arrayed the output increases due to the coupling effect. For instance, stacking two cabinets on top
of each other with the top one inverted gives around 4.5 dB increase in the m id/high section, ideal
for long throw in large halls, sports stadium s, etc. Mounting the bass drivers close to each other
gives the sam e gain at the low end. When the system is arrayed for wider angle coverage with
cabinets side by side the gain is in the order of 3db.
TQ-440SP manual

QLight series
Choosing the best location
It was stated earlier that the TQ-440SP’s tightly controlled directivity gives it essentially point and
shoot qualities. Every room has its own unique set of characteristics that affect any sound
introduced into the room . These include reverberation reflections and decay tim e, sound
absorption of m aterials used, tem perature and hum idity, etc. A degree of experim entation with
different locations (if possible) is best, especially if you are perm anently installing the speaker and
have particular requirem ents where you want to concentrate the sound into a specific area.
Any boundary like a wall or floor will lift certain frequencies. If you are fixing the unit to a wall, or
in a corner then a lift at the bass end is to be expected and it m ay sound rather boom y. Either
reduce the low end by m eans of a graphic equaliser or m ove the speaker.
Room s with a lot of soft furnishings, curtains and drapes will absorb sound, especially at high
frequencies. These room s can sound rather dead and m ay appear to need m ore am plifier power to
generate high SPL’s but have the advantage that the sound needs less equalisation and is easier to
control. In this case the listener receives m ainly direct sound, that is the sound em anating directly
from the loudspeaker, with little reflected sound.
If the room has a lot of hard, exposed surfaces such as wooden floors, brick or plaster walls or
glass windows, these will reflect the sound, causing it to bounce around the room and sounding
over bright. These room s also tend to have various resonances that will be excited by high SPL’s.
Listening in the m iddle of the room you will hear a lot of reflected sound in com parison with the
direct sound. Care is needed with speaker positioning, SPL’s and equalisation. If the room is large
and very reverberant then bass roll-off below about 250 Hz m ay be required to ensure a
reasonable level of intelligibility.
For long, narrow room s the traditional left and right stacks (floor, wall m ounted or flown) can
suffice with good stereo im aging in the centre of the room . For m ulti-tier venues such as theatres,
speakers should be flown or wall m ounted to project into each tier. In highly reverberant room s
often a central cluster is the best option. This acts as a virtual point source with all the sound
em anating from one point in the room , but path lengths should be carefully calculated.
The relationship between sound pressure level and distance is an “inverse square law” so
rem em ber that every tim e the distance from the sound source is doubled the sound level
decreases by 6dB. For every 3dB increase of speaker output you need a doubling of input power
and you can work out the Wattage input needed to give the required SPL levels at various
distances from the loudspeaker(s).
When speakers are flown in free space then boundary effects are m inim ised. The result is a
sm ooth frequency response without any boost at odd frequencies, but the bass end m ay appear
subjectively light. In this case you will need floor m ounted sub-bass, to bring the low end up.

Maintenance
Should a fault develop with the am plifier m odule, we recom m end that you rem ove the m odule as
described below and return it to a qualified Turbosound service centre for repair. The m odule
contains no user-serviceable parts, and the warranty will be invalidated if unauthorised repairs are
carried out.
If one of the drive units in the cabinet should cease functioning and needs a replacem ent recone or
diaphragm you are advised to rem ove the faulty unit from the cabinet and send it to a professional
recone service authorised to recone Turbosound loudspeakers. This will ensure the continued high
perform ance of your TQ-440SP.
Removal of the Amplifier module
1. Release the four M5 Allen head bolts securing the am plifier m odule to the rear of the cabinet
and disconnect the Molex 4-way connector from the PCB. The m odule can now be lifted clear
of the cabinet and set aside.
2. Replacem ent is a straightforward reversal of the above procedure. Take care to connect the
Molex connector securely to the PCB (it is polarised and cannot be connected incorrectly)
before replacing and tightening the four M5 Allen head bolts.
Removal of the 12”/1” driver
1. Unscrew the eight countersunk screws from the two vertical battens which hold the protective
grille in place. Be careful when rem oving the grille as it is under tension and m ay spring
outwards when released. Set the battens, grille and fixing screws aside for later re-assem bly.
2. Undo the eight M6 x 30m m Allen head bolts holding the driver in place and carefully pull it
out and away from the cabinet. WARNING - This unit is heavy! You will notice that the 1” high
frequency driver is attached to the back of the 12” low frequency driver by its screw adapter.
Disconnect the cables from both HF and LF units and com pletely rem ove the driver assem bly
from the cabinet. Make a note of the driver polarity for later reconnection.
3. Separate the drive units by unscrewing the high frequency driver anti-clockwise and lift it
away from the low frequency driver. Depending on which section needs servicing, the
appropriate drive unit should be returned to an authorised Turbosound service centre.
4. To reinstate the drivers, sim ply reverse the above procedure m aking sure you observe the
correct polarity when reconnecting the cables back into the term inals of the drive units.

Removal of the midrange drive unit
If the m idrange drive unit requires m aintenance, it will first be necessary to rem ove the am plifier
m odule. The m idrange driver is held in place by a M10 x 25m m bolt through the rear of the
cabinet into the back plate of the drive unit underneath the am plifier m odule. Once this is released
the m idrange horn and drive unit assem bly can be rem oved.
1. Rem ove the am plifier m odule as described above and set it aside.
2. The M10 bolt securing the m idrange driver will now be accessible in a recess in the enclosure
rear panel. Using a 17m m socket, unscrew the bolt and set aside for later re-assem bly.
3. Unscrew the eight countersunk screws from the two vertical battens which hold the protective
grille in place. Be careful when rem oving the grille as it is under tension and m ay spring
outwards when released. Set the battens, grille and fixing screws aside for later re-assem bly.
4. The m idrange horn is secured through the m ounting flange with four #10 x 1/12” pan head
wood screws. Unscrew these and lift out the horn and driver assem bly.
5. Disconnect the cables, m aking a note of the polarity, and carefully lift the driver clear.
