In the Long Throw Series by artist Anthea Caddy, two parabolic speakers built specifically for the purpose throw sound at each other. Each emits a sound beam up to three kilometers long and a good 60 centimeters in diameter, but also reflects back the sound hitting it. The decisive factor here is the environment in which the loudspeakers are set up. The nature of the surrounding space has an effect on the acoustic long throws even more than the actual sound material and the design of the devices. It reflects and refracts sound, impressively demonstrating how space and form affect sound and its properties. The behavior of sound is thereby illustrated while its reception by the listeners is put to the test by means of this installation work mounted in the outdoor area of HKW’s grounds. The audience is physically confronted with a completely different organism: a physical, energetic sound body in the truest sense of the word.
