Why Soundsphere loudspeakers work so well... Soundsphere loudspeakers produce a diffuse sound field that will not sound harsh or blaring anywhere over their broad coverage area. Listeners seldom perceive a source of sound, but rather a field of sound that appears to come from everywhere. Voice announcements and music are more pleasing and less intrusive than with conventional loudspeakers, and fewer speakers are needed to cover a given area. Fewer sources of sound mean simpler sound systems and fewer intelligibility problems in acoustically difficult spaces.
