The first product of Gradient, the Gradient 1.0 was an end result of extensive research of room – loudspeaker interaction made by Jorma Salmi and Anders Weckström in the beginning of 1980’s. The first speakers were sold to Finnish music university, Sibelius Academy. For the consumer market, the speaker came in autumn 1984.
Gradient, known for its stunningly sounding, slightly strange looking speakers, surprised the public with a conventional-looking floorstand loudspeaker in 1995. However, from a technical point of view, the product was not conventional, as it received features from a Revolution-model published a year earlier.
In 1998, a new version of Evidence was introduced. The volume of the loudspeaker bass cabinet increased by one and a half litres, and at the same time the sound image was slightly elevated, as the loudspeaker was 10 cm higher than its predecessor.
In 2006, Gradient released the Evidence MK III. The model used a new larger diameter coaxial element. As a new finishing option, solid maple was offered in addition to the cherry and black painted cherry.
In 2011, Gradient Evidence was modernized. The base and cover of the new MK IV were made of high-quality plywood, which received genuine ash veneer. At an additional price, oak, birch and walnut veneered parts. The woofer changed slightly larger, otherwise the speaker was technically similar to the previous MK III model.
Gradient Laura was hand built in Järvenpää, Finland during the years 2008 - 2009. Laura continued the compact speaker family based on the coaxial one point source. It also had two passive radiators at the back of the speaker cabinet. The beautiful cabinet was made of plywood. Due to the curved form of the walls the cabinet was extremely rigid.
