With LAMBDA, Verena Hutter has developed a loudspeaker in which the sound is optimised by geometry. The loudspeaker amplifies the sound purely by virtue of its shape. That is why the loudspeaker has not just one sound opening, but two. Following an acoustic principle from instrument making, it uses both the front and rear sound of a loudspeaker module. The result: 50% more sound volume, a wider frequency and improved sound quality with the same loudspeaker module.
