Soft Cells – at a glance - Kvadrat

Soft Cells
The Soft Cells panels typically deliver Class-C acoustic performance.
In doing so, they rely on two layers of tensioned textile.
In order to achieve the most satisfying acoustic performance, the
planner and acoustic expert can adjust the amount and placement
of Soft Cells to suit the functionality of the room.
The technical specifications of Soft Cells show efficient sound
absorption in the important frequency area of speech intelligibility.
