Overcoming “Acoustical Nightmares” 
QFlex comprises a complete range of digitally steerable, multichannel array loudspeaker 
systems for the professional installation market. Purpose-designed for applications with 
exceptionally problematic acoustics, QFlex technology gives the system designer a unique 
set of tools for controlling sound in large, acoustically challenging, highly reverberant spaces – 
typically involving expansive surfaces of glass, metal, concrete or stone.
QFlex is revolutionary in being able to achieve even coverage and sound pressure levels across 
the full listening plane. By creating an asymmetrical pattern, QFlex can produce equivalent SPL 
results in both the near and far eld. Precise full-range beam control, effective to frequencies 
beyond 12 kHz, allows the system designer to steer the QFlex beam away from surfaces that 
cause reections. This makes QFlex the rst digitally steerable array to maintain music quality 
over the desired area of coverage, all in a very architecturally pleasing package.
Which model do I choose ?
The QFlex system you specify depends on a number of criteria:
Distance 
Effective coverage at a greater distance 
requires a larger QFlex column. Typically, 
as a rule of thumb, a QFlex 16 is effective 
over distances of up to 20 m (66 ft) and a 
QFlex 64 in excess of 100 m (328 ft).
Low Frequency Control 
The longer the column, the more 
effective the control and steering at 
lower frequencies. 
QFlex 16 is effective to 700 Hz and QFlex 
64 to 110 Hz.
SPL Requirements
Larger QFlex arrays will produce higher 
SPL levels. This is the case with all 
loudspeakers, as there are more drivers 
and amplier channels producing sound. 
QFlex can generate substantial SPL levels 
at considerable distance, with its high 
amplier count producing more available 
headroom than any column in its class. 
Qex is unique in that every transducer 
has its own dedicated amplier channel.
