Ecophon Solo Heptagon is an acoustic solution, primarily when it is not possible to install a wall-to-wall ceiling. Solo Heptagon is suitable in buildings where the room volume could be maintained or as an option when TABS (Thermally Activated Building System) is selected as cooling system. Solo Heptagon is an unframed free hanging unit offering a high degree of design possibilities both regarding colours and suspension systems. The three different suspension systems using Adjustable wire hangers, Rigid hanger or Adjust brackets in combination with the engineered Connect Absorber anchor (patent pending) give opportunities to create several layers and angles.
