TS-A Series: High Dynamic Range

IMPP (Injection-Molded Polypropylene) Composite Cone
An extremely rigid yet lightweight cone is vital to prevent cone failure at high sound pressure levels. Pioneer’s IMPP Composite Cones meet this need perfectly. CAE (computer-aided engineering) has been applied to create a surface spoke design that ensures high durability and rigidity of the cone.
