The “bass boxes” - built by Hans van Koolwijk in collaboration with composer and sound artist Hans van Eck - consist of four bamboo flutes.
They produce sound by the action of two powerful bass speakers. These speakers act as electric air pumps that direct precisely calibrated gusts of air into four flutes and thereby create rhythmic patterns. The bass boxes can be played like a 'normal' musical instrument with the help of a custom-made synthesiser - the "pulsor" - and a mixing desk, enabling the player to create countless variations of sound and rhythm.
