Sigma:Zero as a brand was born many years ago as the brainchild of the artist and inventor, Per R.Ø. Salkowitsch, in the effort of creating a perfect dipole loudspeaker. This Loudspeaker later grew into the Origo design. Following the success of the Origo, other designs were added. When fellow artists started to notice Sigma:Zero, helping them in realizing their designs became part of business. Today, adding sound, light and mechatronics to exhibitions has grown into a large portion of business, and it is a lot of fun.
