Arc

AT-05

The AT-05 is the smallest passive fullrange speaker of the Arc series. It was developed for fixed installations and captivates with its broadband reproduction and compact dimensions. The loudspeaker is optimized for speech and music transmission at short distances.
In addition to their outstanding technical features, the models of the Arc series are generally characterized by their attractive design.

Main features
