Pioneer TS-W311D4 Sub-woofer

Pioneer TS-W311D4 Sub-woofer

Pioneer’s IMPP Composite Cone is newly re-designed to deliver a durable cone structure for accurate, yet powerful bass. The subwoofer now provides a single piece cone and drive cone, in addition to a lightweight and rigid dust cap. This combination offers more rigidity throughout the cone versus competitors in its class. An extremely durable, yet lightweight cone is vital to prevent cone failure at high sound pressure levels.

The TS-W311D4 utilizes a highly rigid, fully-enclosed, single piece basket, derived from our world-record holding SPL competition subwoofers, to help minimize the vibration throughout the subwoofer and increase the driving force to the cone, producing louder and rhythmical bass. Improved stiffness of the basket provides for less sound leaks creating more clear and powerful bass.

All fast moving parts and friction will create heat and too much heat creates unwanted audio results. The TS-W311D4 is designed with ventilation holes to improve air flow and release heat keeping the piston cool for better performance.
