    RAL color program means that it can melt into any architecture. The X8 is an ideal live monitor capable of accurately translating the signature of large systems at FOH position or in control rooms. The X8 features a pristine L-Acoustics sonic signature, a high SPL capability and extended LF resources in a compact format.

    Loudspeaker congurations X8 point source Deployed as a standalone point source, an X8 system operates over the nominal bandwidth of the X8 enclosure. The [X8] preset allows for a reference frequency response in short throw applications. The X8 enclosure is driven by the LA4X / LA8 / LA12X amplied controllers.
