Item number: 1204-XXXXX

The mobile LX-501 combines and optimizes the principles of line array technology in a compact yet powerful system. It achieves first-class directivity, even dispersion and a long reach. The unit can be placed inconspicuously in the room thanks to its slim design.
The loudspeaker system can be optimally combined with passive and active subwoofers of the X and Perform series and delivers best results with Fohhn DSP power amplifiers.
