Think fast

Our custom designed 4” woofers are smaller, faster and more precise than our competitors. SA brings you a life-like and engaging sound that can only be delivered by a fast loudspeaker and the new SA mantra 50 is the best way we have ever proved our philosophy.



Think innovation

SA has been designing loudspeakers with small drive units since 1984 and long before everyone else. This is our secret. We are specialised in big sound, precision and involving musicality and the 50 is a unique loudspeaker with a talent for surprising those who decide live with it.


The 50 model:

A history of innovation

At SA, a loudspeaker is more than just a loudspeaker. It is a piece of innovation. Since 2000, a 50-model has been a powerful 2½-way concept of four 4” woofers and a 1” tweeter. We have now refined materials and technologies for more than a decade and today SA mantra 50 is the most perfectly balanced 50-model we have ever made.



The man and his mantra

System Audio A/S was founded in 1984 by Ole Witthøft because he could not find any speakers that could live up to his idea of being close to the artists when listening to music at home.


He had discovered that speakers must be constructed and designed in accordance with a specific system that has named his company.



Reduction as a design philosophy

SA speakers begin their life at Ole's table. Some of the world’s best experts in acoustics, mechanics and electronics are involved in the product development a new speaker is only put into production when everyone is happy with it.
One of Ole's philosophies is about reduction. On each loudspeaker you will see the reduction as an absence of decoration. Inside the speaker you see reduction as an obvious simplicity of the design.
It is also reduction, which drives us to reduce the weight of the moving mass of our drive units, because it improves the sound. When we reduce the speaker’s dependence of the room acoustics, it is also a way to use the philosophy.
It is a waste of the user's resources to make things complicated. Simplification of every little detail optimizes the experience.
In other words: less is more.
