LC-220

The LC-220 is a passive line source speaker for fixed installations. It is optimized for excellent speech reproduction and is ideally suited to both indoor and outdoor applications thanks to its weatherproof aluminum enclosure. The renowned Fohhn line source speakers combine the advantages of line arrays – such as directionality, homogeneous dispersion and reach – in a compact system. The slim aluminum housing enables perfect visual integration into the room architecture.
