Planning of our adjustable acoustics in new buildings

A brief overview regarding implementation and mounting:


> A schematic lay-out

The system may be installed above a suspended, sound transparent ceiling making it invisible.

The system includes a number of absorber-rows mounted parallel to each other on tracks, flush to the ceiling.  The more absorbers the greater a span of reverberation is obtained enabling even more types of music to be performed in the same room – all with great acoustics.

Ideally the average spacing between absorber-rows is 80-100 cm center-to-center. However, they do not have to be spaced evenly but are mounted where there is room in the ceiling. The absorbers are 70 cm wide when fully inflated.

The system takes 120 cm of height to incorporate. It is important to note that they only take up visual space – not acoustical since they are close to transparent to the sound when inactive.

Each absorber is connected to a common air-duct with a connectivity piece. First the air-duct is mounted on one or two parallel  walls close to the ceiling. A connectivity piece is placed at the position where the absorber will be mounted to a track.

Then  tracks are fastened to the ceiling exactly aligned with the connectivity piece. Absorbers are fitted onto tracks and the fan and control system is connected.



The aQtubes are customized to fit certain areas in for instance a concert hall for classical music, which occasionally presents amplified music.

They may be mounted horizontally on wires stretched between trusses and raised towards the ceiling by hoists, or mounted vertically along side walls or in mid air fitted directly to a truss.

Unlike other absorption types, apart from absorbing the most important frequencies, they even work well in mid air not placed close to a surface!

Especially vertical Tubes are rigged very quickly and effortlessly. They are easily inflated by a dedicated micro-ventilator on each Tube inter-connected with low voltage cables, or pre-inflated with a bigger fan.

Check with Flex Acoustics or rigging companies for suggestions on how to make a solution for your specific hall.

The absorbers are simply stowed away in flight cases when not in use.
