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 reections. 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 amplier channels producing sound.
QFlex can generate substantial SPL levels
at considerable distance, with its high
amplier count producing more available
headroom than any column in its class.
Qex is unique in that every transducer
has its own dedicated amplier channel.
