Soft Cells Broadline
According to ISO 11654, Soft Cells Broadline panels deliver Class-A
sound absorption with high performance textiles. They feature acoustic
padding behind a front textile layer.
Thanks to a recent design update, Soft Cells Broadline panels can be
configured to deliver Class-A absorption with the majority of textiles.
Soft Cells Broadline panels are suitable for all rooms where a
premium acoustic solution is required. They are also ideal for smaller
interior settings, as they can take up less space while retaining high
acoustic performance.
The technical specifications of Soft Cells Broadline show very efficient
sound absorption across the better part of the frequency area.
