Hemisphere
Point-source Emanation Loudspeaker
The Hemisphere (and its sister, the Six-channel Hemisphere) are unique, versatile loudspeakers that will change the way you think about amplified sound in live performances, sound installations, and non-traditional sonic/art scenarios.
Amplifed sound usually has a very different character from unamplified sound because of the way it interacts with its environment. Unamplified sound radiates out from its source in all directions, interacting with the walls, floor, ceiling, etc., while most loudspeakers project sound in one direction only. Typical "stereo" or "surround sound" systems have a "sweet spot" where they sound best, and the spatial illusion they create is destroyed if the listener is not properly positioned.
Hemispherical speakers are entirely different. They produce "localized" sound that emanates from the speaker's position and interacts with a room's natural acoustics. The speakers have no front or back, and no sweet spot for listening. This allows electronically-produced sound to take on the characteristic intimacy of unamplified sound, changing the experience of both performer and audience, and improving the quality of hybrid performances which mix acoustic and electronic instruments.
The information below relates to the standard monaural Hemisphere speaker. Six-channel Hemispheres are also available.
