Gaze upon what is purported to be the biggest subwoofer in the world – The ‘Real Total Horn’, built beneath its own listening room -

Royal Device has on its own developped and built in Italy the biggest subwoofer of the world for an AUDIO/VIDEO room that can be also considered as the greatest AUDIO ROOM for private music listening of the world. The Royal Device audio room belongs to Roberto – the audio designer who made it.

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.

  • SUBWOOFER horns are built underneath the floor in a cavity of 1 meter deep. Each horn is driven by 8 x 18″ (47 cm) woofers. A total of 16 woofers.

  • Each horn is 9.5 meters long and has a floor mouth area of 2.2 square meters and reproduce starting from 10 Hertz FULL POWER. The real mouth area IS NOT the one on the floor. The real mouth have to be considered together with the side vertical frontal panels. The total horn is calculated onto the listening point considering the side walls and the ceiling loadings. This reduces the floor mouth that is not in open air.

(hmmm … wouldn’t that drum kit create some unwanted vibration?)
