The Iris IP membrane, developed by our acoustic engineers, embodies outdoor sound performance. Its composition ingeniously combines the rigidity of polypropylene with injected carbon fibers, guaranteeing a dynamic and rich sound. Designed to be resistant to water infiltration, dust, and UV rays, it is specially designed for Focal outdoor products. Its tropicalization treatment reinforces its resistance to the most extreme climatic conditions, for great durability.

Specialists in speaker and tweeter cones, our acoustic engineers work as much on the materials as on the cone shapes. This is what they did with the famous inverted dome tweeter, which they developed, notably by proposing a new "M" shape that brings two decisive advantages: an even lower sound directivity, for an ever more flexible listening position, and a significant increase in rigidity for the dome, which further reduces distortion and thus allows for quality sound.
