When it comes to sound reproduction we believe there's only one relevant parameter: How close can we come to the originally recorded sound. We feel an obligation not to disturb the intentions of the artist by adding unnatural elements to the acoustic image.
Therefore all Bang & Olufsen loudspeakers share the same goal. They differ in size and shape and in terms of sound pressure level. But they are all developed to reproduce the natural, unaltered sound as closely as possible.
