Included in the acoustic suspension design were a 7-element filter, a long-throw spider 20cm bass long-fiber paper cone with rubber surround and 48,000Mx magnet, an acoustically sealed 13cm mid driver with 41,500Mx magnet and a 2,5cm high friver with lightweight CAB cone (cellulosic Butyrate Acetate) with an added phase plug.
