QLight™ series
SYSTEM REQUIREMENTS
QLight™ series passive loudspeaker enclosures require only one amplifier channel for correct
operation, the frequency splitting between the low frequency driver and the high frequency driver
being accomplished by the internal passive crossover network built into each enclosure. If
subwoofer enclosures are used as part of a bi-amplified system in conjunction with QLight™
series 2-way enclosures to extend low frequency response, additional amplifier channels and
external electronic crossovers will be required. The Turbosound LMS-D6 and LMS-4 digital
loudspeaker management systems are recommended for this purpose, as well as other
professional quality digital controllers.
Bi-amplified loudspeaker enclosures require the use of one amplifier channel per frequency band
for correct operation. Frequency splitting between the low frequency driver, and the mid and high
frequency section drivers is accomplished by an external electronic crossover; while frequency
splitting between the mid frequency driver and the high frequency driver in 3-way models (TQ-
445) is handled by an internal passive crossover.
Dedicated subwoofer enclosures require an additional amplifier channel when used as part of an
extended frequency system. Frequency splitting between it and a QLight™ series mid-high
enclosure is accomplished by an external crossover. Turbosound digital loudspeaker management
systems are recommended for this purpose.
Amplifier considerations
Turbosound speaker enclosures should be driven by high quality power amplifiers designed for
true professional use. Such amplifiers will have balanced inputs, DC and RF fault protection, and
well designed cooling systems for reliability. Turbosound power amplifiers such as the T-45 and T-
25 are recommended for this purpose.
The program power listed in the loudspeaker’s technical specification is the best guide to the size
of amplifier required for general purpose applications. The amplifier should therefore be capable
of delivering long term broadband power equal to the loudspeaker’s program power rating at the
loudspeaker’s stated nominal impedance. This approach allows sufficient headroom to generate
good dynamic range.
RECOMMENDED AMPLIFIER POWER RATINGS:
The amplifier's rated r.m.s. continuous power output (20Hz – 20kHz, per
channel) should be equal to the program power handling of the
loudspeaker at its nominal impedance.

QLight™ series
In general, the more powerful the amplifier, the better it will sound, provided that it is not driven
into sustained clipping. It should be understood that overdriving an insufficiently powered
amplifier is more likely to cause loudspeaker damage – the total energy in a heavily clipped signal
is far higher than in an unclipped signal – than operating a more powerful amplifier within its
ratings.
One loudspeaker management system can be used to feed several amplifiers as long as all the
amplifiers are the same (or have the same gain ratings). More than one loudspeaker management
system may be required if the amplifiers are of different gain or type. Please contact your dealer if
you require help in this area.
Equalisation
QLight™ series enclosures are designed to provide smooth and even frequency response. They do
not need excessive amounts of external equalisation to overcome the sonic deficiencies often
found in many lesser designs.
Should an extended frequency response be required at more than moderate sound pressure
levels, the use of complementary Turbosound subwoofer enclosures is strongly recommended.
In order to compensate for the room acoustics, Qlight™ series enclosures require only minimal
equalisation. As in any system, over-equalisation introduces phase shifts, distortion and a
reduction in headroom, usually causing more problems than it cures. Under most circumstances a
1/3 or 1/2 octave graphic equaliser will generally be adequate, with the fader settings applied
smoothly and as little as possible for the required room compensation. Most rooms will have
resonances that will be excited at particular frequencies needing some cut to help tame the sound.
These problems are most pronounced at the lower frequencies where loudspeakers generally
exhibit very little directional control. If you find that the system needs a lot of boost at lower
frequencies you may need additional sub-bass units. It is good practice to use as little equalisation
as possible, aiming to cut frequencies rather than adding large amounts of boost.
Dispersion
Qlight™ series loudspeakers fall broadly into two categories of dispersion pattern: wide and
medium. While a wide horizontal coverage pattern of approximately 80° to 100° is appropriate for
a majority of small to medium venues, one of the design features of the TQ-445 is a tightly
controlled 60º horizontal by 40º vertical dispersion pattern at mid and high frequencies. This gives
many user advantages and eases placement decisions, being essentially a point and shoot system.
The more focused directivity results in greater projection capabilities, making the TQ-445 very
suitable for theatre and small auditorium applications. Remember that a 60º horizontal polar
pattern equals an angle of 30º either side of the centre line at which the sound pressure level is

QLight™ series
6dB down with respect to centre, (averaged over the whole frequency range of the loudspeaker).
Converging Elliptical Waveguide™
A design feature of the TQ-308, TQ-310 and TQ-315 is the Converging Elliptical Waveguide™
(CEW™), available in two directivity patterns: 100° x 60° and 80° x 50°. This gives many user
advantages. The comparatively short flare length allows the HF and LF components to be
physically aligned in the cabinet, so ensuring coherent arrival at the listener’s ear irrespective of
distance from the loudspeaker. The elliptical format shapes the wavefront smoothly, and
eliminates reflections in the throat area. Additionally this design does not suffer from the
distortion typical of horns employing diffraction edges.
The waveguides can be removed and rotated through 90º in the cabinet, which allows the
products to be installed in either vertical or horizontal formats while retaining the required
coverage.
To rotate the horn, first remove the grille by undoing the countersunk Allen head screws which
retain the grille from the sides of the cabinets. Remove the four screws holding the horn flange in
place. Lift the horn and driver assembly out, rotate it through 90º and replace the fixing screws.
Replace the grille.

MOUNTING AND FIXING
Rigging Hardware
A versatile range of mounting hardware is available that allows enclosures to be used in a variety
of ways, in either mobile applications or permanent installations.
A top hat stand type fitting is fitted to the base of
QLight™ series full range and mid-high cabinets
for use with 35mm diameter loudspeaker stands. A
pole mount socket is also fitted to the top of the
QLight™ sub-bass cabinets. This allows two
enclosures to be used together as an extended
frequency range system as shown here with the
TQ-445 mounted above the TQ-425 on the optional
35mm diameter straight pole. This enables a
minimum footprint for the system and ensures the
correct vertical distance between cabinets.
Internal M10 threaded rigging points are provided in several
locations on the cabinet – generally on the top, bottom, sides
and back – enabling enclosures to be suspended quickly and
inexpensively using optional M10 shoulder eyebolts.
Downward inclination of the enclosure can be adjusted using
an additional rigging point on the rear of the cabinet. Note:
these rigging points are intended to hang a single box only and
must NOT be used to rig a second enclosure in a vertical
column.

RT-767 ring type flying points. Rigging points
are provided on the top and rear of the TQ-310
and TQ-315 for use with optional RT-767 rings,
enabling cabinets to be rigged in permanent
installations and for mobile applications.
Downward inclination of the enclosure can be
adjusted using the third RT-767 rigging point on
the rear of the cabinet
Swivel brackets provide a means of wall mounting some QLight™ series enclosures (TQ-308, TQ-
310 and TQ-315) in a horizontal or vertical orientation. They are attached to the box using the
integral pole mount fitting at the bottom and the M8 internal rigging point on the top of the
cabinet. For applications requiring a horizontal format, an additional scaffold clamp assembly can
be used with swivel brackets for attaching to lighting grids.

Side-mounted flying strips can be fitted to the
sides of TQ-445 enclosures by removing the
countersunk bolts on the top and sides of the
cabinet and replacing them with the M10 bolts
supplied with the hardware. Two flying strips are
required for each enclosure; one attached to each
side. This method offers a simple and cost
effective way of flying single enclosures in
permanent installations. Enclosures may also be
arranged in a vertical column by coupling the
flying strips together using QL-75 quicklinks or
shackles. Turbosound flying strips are
individually load tested. When used in this way
the load is taken through the flying strips rather
than through the woodwork of the enclosure.
Side-mounted flying strips can be fitted to the sides of Qlight™ series subwoofer cabinets to
enable subwoofer enclosures to be flown as part of a permanent installation. Two different lengths
of flying strips are optionally available for flying the enclosure in either a vertical or horizontal
orientation. These are fitted by removing the countersunk bolts on the top and sides of the cabinet
and replacing them with the M10 bolts provided with the hardware. Two flying strips are required
for each enclosure. This method offers a simple and cost effective method of flying single or
multiple enclosures, with the load being taken through the steel strips rather than through the
woodwork of the enclosure. Enclosures may be arranged in a vertical column if required by
coupling the flying strips together using QL-75 quicklinks or shackles. Turbosound flying strips are
load tested.
WARNING: Rigging eyebolts must not be used for flying this enclosure. You must use the optional
Turbosound steel flying strips described above.

Single point mount options include a universal FB-12 flybar assembly for
use with the TQ-445 and this enables the use of several different fixing
methods. The illustration at right shows the FB-12 with three different
methods of suspending the TQ-445 cabinet: a unilock fitting; a scaffold
clamp; and a pick-up point adapter.
To attach the flybar first remove the threaded plastic plugs filling the
rigging points on the top of the cabinet. Fit the flybar to the cabinet
using the captive M10 shoulder eyebolts supplied with the flybar
assembly. There are 12 attachment points equally spaced along the
length of the spine of the flybar. Depending on which point is chosen for
the given attachment system, a wide range of downward inclination
angles can be achieved over a range of approximately 70 degrees. The
design of the flybar even allows for upward angles, for example for
coverage of balconies that are higher than the loudspeaker location.
The FB-12 flybar assembly comes supplied with a U-6 Unilock fitting,
which provides a single attachment point. The point at which the Unilock is attached to the flybar
determines the vertical angle of the loudspeaker as shown in the table following.
A pick-up point adapter offers a further single attachment point. This option provides fast
adjustment of vertical angle. The point at which the eyebolt adapter is attached to the flybar
determines the vertical angle of the loudspeaker as shown in the table following.
An aluminium scaffold clamp is attached to the fly bar by means of a simple clevis coupler. It is
designed to rotate horizontally through 360° in order to enable accurate positioning of the
loudspeaker. The point at which the scaffold clamp is attached to the fly bar determines the
vertical angle of the loudspeaker as shown in the table following.

Permanent installations
Any installation, whether temporary or permanent, must 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 combined weight of the sound system, its cables and the rigging system must be
safely carried by the points at which attachment is made to the building or structure. Great care
must be taken in selecting the attachment points and methods, being absolutely sure of the load
carrying capacity of points chosen.
NOTE: The rigging of loudspeaker systems is an extremely serious matter with potentially lethal
consequences should anything go wrong. It is of vital importance 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 number one priority. Turbosound accepts no responsibility for any accident,
damage or failure of any rigged system. This rigging information is specifically related to the
requirements of Qlight™ series enclosures only. For more detailed information 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 company.
Choosing the best location
When using any QLight™ system, certain room parameters will affect the resultant sound quality
and coverage. For example, any boundary like a wall or floor will lift certain frequencies. If you are
placing the unit in a corner then a lift at the bass end is to be expected and it may sound rather
boomy. This can be compensated for moving the speaker or cutting low frequencies with a
graphic equaliser.
When speakers are flown in free space then boundary effects are minimised. The result is a
smooth frequency response without any boost at odd frequencies, but the bass end may appear
subjectively light. In this case increase the sub-bass level to bring the low end up.
The relationship between sound pressure level and distance is an “inverse square law” so
remember that every time 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).
