Adjustable acoustic for auditorias

Mobile and variable bass & mid absorption products

Flex Acoustics offers two products which both absorb low- and mid-frequency sound for sonically great indoor concerts:

  • aQflex – variable acoustics for permanent installation
  • aQtube – mobile acoustics for temporary placement

The two products are based on the same patented technology of inflated membranes and the same basic truth: low frequency sound is extremely important in concert hall acoustics. In fact the products, when activated, control linearly sound within the fundamental range of most music instruments: 63 Hz – 1 kHz.

The aQflex is ideal for concert halls, multipurpose halls and music education institutions – any hall where a variety of musical styles are played. It is activated within 5 min. by the push of a button. The aQtube can be stowed away in the venue when not in use. Temporary vertical placement on trusses at the wall or vertically on wires close to the ceiling.

The products, which are being manufactured by and supported in most of the World by Gerriets, is the proud result of 8 years of research and development. The design is purely driven by unique acoustic performance. They even sell at a very acceptable price.

They are CE certified meaning that all safety, fire and quality requirements are fulfilled to the high standards of the European market. They have also passed safety requirements of other countries. The plastic is recyclable.

The technology increases the potential of any hall; pave the way for an optimized musical experience for musicians, audience, teachers and pupils alike.
