Staff member
Royal Device has on its own developped and built the biggest subwoofer of the world for an AUDIO/VIDEO room that can be also considered as the biggest AUDIO ROOM for private music listening of the world. The audio reproduction is focused on the speakers output capability more than electric power output of the amplifiers with no need of KWatts power supply lines, releasing more than 110 dB/1W/1 meter sensitivity starting from below 10 Hz focused on the listening position.
