Focal applies the same technology they use in their studio and audiophile-grade home systems to their Integration line of car speakers. Integration IC 165 6-3/4" speaker cones are made of Polyglass, a material that combines the warm sound of cellulose with the strength of glass, for a woofer that plays accurately with no added resonances.
