Acoustic picture

Description

The acoustic picture carries a freely selectable motif, printed in high resolution onto an acoustically transparent display fabric. Height and width can be adapted to the motif. raumton advises on resolution and print formats and assists with cropping and conversion. Because of its low dead weight, mounting on any wall surface is straightforward.
