aQflex™ Acoustic System

  • Flexible absorption membrane for use in permanent installations. Control system included.
  • The aQflex™ system consists of inflatable absorption membranes for low frequency range, air pump ventilation system and is permanently installed on a TRUMPF 95 track system. The system can be turned on or off at a press of a button.


The patented aQflex™ absorber system allows for changing the acoustics of a room to fit any purpose.
The aQflex™ has three advantages over normal acoustic treament:

  • It can alter the acoustics of a room.
  • It adjusts also the acoustics at low frequencies scientifically proven to be important most notably at amplified music concerts.
  • It is most active in the 63-1000 Hz domain at the fundamental frequencies of musical instruments.
  • For the first time the reverberation time can be adjusted to the multifunctional use between classical, unplugged or electronic music.

Technical Data

  • The absorbers can be temporarily mounted (aQtube™) on wires or permanently installed (aQflex™) on Gerriets tracks.
  • For stationary installation the variable ON/OFF system is recommended, for temporary installation the preinflated
    version is preferred.
  • The system is CE certified.
  • Meets the flame retardent classification DIN EN 1350-1 in the class B,s1-d0 and the US standard NFPA 701.
  • The system is very lightweighted and therefore suitable to be retrofitted onto existing ceiling constructions.
  • In the mobile version supplied with a 24V blower integrated in the screw cap, which guarantees a permanent
    ventilation of the mobile system.
  • The system for permanent installation includes absorbers, tracks, air supply system and control box.
  • Simple, wall mounted ON/OFF switch panel used for operation of system.
  • Air supply requires a 230 V single phase circuit.
  • The consumption of electricity is about 50 to 100 Watt while de-inflating.
  • Low power use of 10 Watt once absorbers are inflated.
  • Absorbers are connected via an air pipe-line and can be divided into two or more subsystems in order to achieve
    reverberation times in between extremes.
  • A sensor surveys the system at all times.
  • Any hypothetical malfunction is automatically observed.
  • Can be easily retrofitted in most existing halls without much installation work.
  • Absorbers in off position have almost no impact on reverberation but can be retracted to one side if necessary.
