Constantly pursuing innovation is the embodiment of Focal's corporate strategy and that goal involves every facet of the company. From R&D to production to quality control, all our teams are fully involved and focused on this one objective: continual progress through innovation.
In today's world, where globalization and the pursuit of chasing cheaper production methods have tempted most companies to splinter their organizations, Focal has opted to be different. Though we have grown tremendously through the years, our R & D, headquarters and manufacturing facilities remain based in Saint-Etienne (France).
We have learned that true innovation is not simply work carried out at the research department, but is also a question of comprehensive management and the direct control of the different production phases. The example of Beryllium is a significant one. Only three years ago no one was capable of producing tweeters with a pure Beryllium foil dome. Focal innovated a solution based on research and the invention of specific in-house industrial processes.
Such an approach has given us an important advantage over our competitors: we develop our own technology, which allows us to consistently provide true quality production using our own methods. In 2008, the Focal Car range gets richer with a new amplifier line: Solid. This perfectly sums up Focal's commitment for high musical quality from the entry-level contrary to the general tendency that consists in looking for the cheapest prices in priority instead of performance.The result is music standardization and trivialization, which is highly prejudicial to sound quality. Focal cultivates this difference. This is the core strength of our brand and our company. This is the Spirit of Sound. We want to share this with you... It is our Utopia
