SAM Revolution

True to our absolute audiophile purpose, Devialet engineers have passionately traveled the world in search of new speaker models to create as many SAM® profiles as possible. Thanks to SAM Lab, more than 800 speaker models are now SAM-ready. A ginormous leap forward. Yours are more than likely among them.

SAM Lab. A ginormous leap forward.

Back in 2014, it would take us days to measure speaker specs. Each speaker had to be completely stripped apart to examine individual loudspeaker performance, cross-over filters, bodywork, etc.

In a major feat of engineering, our team managed to scale down a full-size laboratory into a single portable and ultra-powerful device: SAM Lab. As a result, we were able to speed up the entire SAM protocol. For lightning-quick speaker analysis.
