Focal applies the same technology they use in their studio and audiophile-grade home systems to their Integration line of car speakers. The Integration ISS 690 component system includes 6"x9" woofers with cones made from Polyglass, a material that combines the warm sound of cellulose with the strength of glass, so they'll play accurately with no added resonances.
