Extended loudspeakers without membranes.

The membrane is reduced to the strict minimum. The purpose of this operation is to have the loudspeaker as silent as possible. But the cylinder of the loudspeaker should still remain suspended around the magnet so that it still vibrates when electric impulses are sent in the loudspeaker.

These vibrations are transmitted through steel wires attached to the cylinder on one side and to a net of tin can resonators on the other end. The tin cans are suspended in the space. So, the original sounds sent in the extended loudspeakers are filtered and reverberated through the installation.

In this sound example, original sounds are feedbacks and sine waves. It was recorded in Hasselt’s Begijnhof (Z33) in 2001 by Jean-Marc Sullon, Patrick Delges and Benoît De Clerck, mixed by Patrick Delges.

Since 2000, this principle has been experimented in various ways : as an installation working automatically and/or used by me and various musicians in performances.

- It has been presented in art galleries :

  • Galerie Rachel Haferkamp (Cologne) ;
  • RLBQ (Marseille) ;
  • Le Gymnase (Besançon) ;
