A Stroll Through the KEF Museum - 1970s

As KEF grew throughout the 1970s so did our technical expertise, with the first implementation of computers in loudspeaker design and measurement. This development would lead to world famous designs such as Reference Series. The 'Total System Design' concept was equally applicable at the entry level with products such as the Celeste III dominating the budget loudspeaker market. To this day, designs such as Blade, LS50 and the new R Series (as well as all of our other products) benefit from the use of Finite Element Analysis and other computer simulations.

Subwoofers can be a major enhancement to any music or movie system, and they’re not incredibly difficult to set up especially with a quality product that has been designed to be user-friendly and high performing.
