About SEAS
SEAS loudspeaker drivers are designed and manufactured in Norway. In the late 1920s, at the Norwegian Institute of Technology (NTH), the first Norwegian electrodynamic loudspeaker drivers were designed. Since then Norwegian engineers have been leading the technology race in driver design. From its founding in 1950 as a spin-off of the Norwegian radio manufacturers Radionette and Tandberg, SEAS has been dedicated to creating loudspeakers with superior sound reproduction. The company, whose name means Scandinavian Electro Acoustic Systems, has remained in the forefront of European driver manufacturers for more than 60 years. During this time, SEAS has evolved its products line – from a wide selection of standard drivers for radio and TV sets to the highly innovative customer influenced Hi-Fi drivers offered today.
