A BassBox is an electronic air pump which pumps wind in measured quantities through flutes, giving rise to rhythmically fascinating sounds. In contrast to what might be expected, the Bass Boxes do not produce bass sounds; rather, one hears rhythmically overblown bamboo flutes which are provided with air from the powerfully vibrating bass loudspeakers. At the moment that the cone of the loudspeaker moves forward the foremost flute sounds, while a small amount of air is drawn into the hindmost flute. As the cone moves backwards the process is reversed. This explains the percussive nature of the sound; there is a constant inhalation and exhalation of air, which moves swiftly through the mouths of the flutes. This creates superbly refined combinations of sounds. The rhythmic patterns can shift with extreme subtlety, but a strict pulse is also possible. www.audiobulb.com
