4  d&b Q-Series 

The Q-Series

The 

Q-Series

 embodies the d&b holistic approach to sound 

reinforcement solutions: integrating loudspeakers, electronics, 
mechanical deployment assemblies, remote control functions and 
setup design tools for precise calculation of array performance. 
Control of dispersion behaviour is a particular fixation at d&b, 
while at the same time keeping the size and weight of systems to 
an absolute minimum. The Q-Series maintains the ”d&b specific” 
combination of a neutral, intelligible sound character that is 
clear and transparent even at high sound pressure levels 
providing the engineer with an efficient, effortless tool and a 
neutral platform. 
The Q-Series loudspeakers are the perfect option for speech and 
music in many theatre and presentation situations, live television 
and orchestral shows, situations where multiple open microphones 
are used and considerable gain before feedback is an absolute 
requirement. The transparency, bandwidth, high power and 
headroom capabilities, also make them ideal for any type of 
amplified music. The scope of applications is intentionally broad, 
ranging from single loudspeakers right through to larger multiple 
cabinet arrays. To this end a variety of technologies are used: 
conventional rotatable CD horns, dipolar driver arrangements, 
low compression vented designs with high excursion drivers and 
toroidal wave shaping devices, all integrated using line array 
principals. 
The 

Q

 and 

Qi loudspeakers

 are designed for mobile and 

installed applications respectively, the Qi versions differing 
only in cabinet construction and mounting hardware. The Q 
loudspeakers are designed for a wide range of small to medium 
scale applications with a clear perspective to provide mobile, 
flexible, configurable array solutions to the most arduous sound 
reinforcement situations. The d&b ArrayCalc calculator predicts 
the performance of arrays, enabling simple and accurate system 
planning. The Qi loudspeakers are intended for permanently 
installed performance spaces where the specification is rider 
driven by the artist or mix engineer’s preferences. Both the 
Qi cabinets and mounting hardware can be properly colour 
matched to interior designs, are mechanically adapted for 
installation use and can provide protection in climatically hostile 
environments.   
The 2-way passively crossed over 

Q1/Qi1, Q7/Qi7

 and 

Q10/Qi10

 loudspeaker cabinets sharing the same physical size, 

shape, rigging and driver compliment. The highest degree of 
constant directivity is maintained using a large frequency overlap 
through the crossover range, while the recessed dipolar positioning 
of the two 10” low frequency drivers mechanically time aligns 
these with the 1.3” exit HF driver. The Q1/Qi1 HF drivers are 

fitted with a toroidal wave shaping device, which have a 75° (h) 
and 75° x 15° (h x v) dispersion pattern respectively, the resulting 
curved coherent wave front allows vertical arrays of multiple 
cabinets to be constructed. The Q7/Qi7 and Q10/Qi10 
loudspeakers also use a 1.3” HF driver fitted to rotatable 75° x 40° 
and 110° x 40° (h x v) constant directivity horns respectively 
allowing them to be configured for use both vertically or 
horizontally. When deployed upright, the Q7/Qi7 and Q10/Qi10 
are accurate stand-alone full range loudspeakers with vertical 
directivity control extending approximately one octave below 
similarly sized biaxial loudspeakers. Their horizontal coverage 
angles can also be used to fulfil near field or infill functions 
for Q1/Qi1 arrays, either flown, stacked or ground supported. 
When deployed horizontally with the horn rotated, the horizontal 
dispersion control of the Q7/Qi7 is maintained down to 
approximately 400 Hz. This performance can be used very 
effectively in critical positions close to open microphones and 
also allows the Q7/Qi7 loudspeakers to be combined as the 
near field element in Q1/Qi1 columns.
The 

Q

Qi

 and 

QiCSA

 subwoofers complete the Series’ sharing 

the same width as the other loudspeakers and having compatible 
flying fittings that enable their use in columns with Q and Qi 
loudspeakers respectively. The Q, Qi and QiCSA-SUB cabinets are 
bass-reflex designs with an 18” high excursion driver. Multiples 
of three Q-SUBs or two Qi-SUBs and one QiCSA-SUB can be 
combined to produce Cardioid Subwoofer Arrays (CSA) when 
driven by the D6 or D12 amplifier. The D12 amplifier incorporates 
d&b SenseDrive technology for accurate control of LF driver 
membranes.
The d&b 

D6

 and 

D12

 dual channel amplifiers realize the 

complete system. They provide two different power ranges, 
incorporate d&b loudspeaker specific configuration information 
and have analog and digital signal inputs and links. These devices 
are specially designed and manufactured by d&b utilizing Digital 
Signal Processing and include switchable functions for precisely 
tailoring system response for a wide variety of applications. A user 
definable 4-band parametric equalizer and a delay capability is 
provided in every amplifier channel to reduce the need for external 
processing devices. The D12 amplifier additionally offers a 
2-Way Active mode and a MIX TOP/SUB output configuration, 
output connector options as well as d&b SenseDrive.
The D6 and D12 amplifiers have 

d&b Remote network

 

interfaces enabling control and monitoring of a large number of 
system functions and extensive system integration capabilities. 
d&b Load monitoring and System check are also incorporated to 
remotely monitor loudspeaker driver status.
