The world’s first, patented HVT (Horizontal Vertical Transforming) technology from Pioneer enables a micro-height sub woofer system to produce bass output and sound of quality equal to that of conventional sub woofer systems.



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.
