The diaphragms for our latest generation of drivers utilize state the of the art, ultra-high modulus carbon fiber fabric skins which are pre-impregnated with a custom formulated, toughened epoxy resin system and consolidated to a Rohacell core under high pressure and heat (265F) in our aluminum tooling. The carbon fiber skins use a revolutionary new fabric whose fibers are arranged in an extremely flat profile with far less crimp angle between the tows that results in substantially lower aerial weight and higher tensile modulus than any other fabric available. With an aerial weight of a mere 2.4 oz/m², this unique fabric enables us to build the highest stiffness to weight ratio cones possible, ensuring pistonic behavior throughout the entire pass band of the driver.
