Pioneer Electronics is giving consumers the power to add more bass to their vehicles with the introduction of its new series of Pioneer and Premier branded Champion Pro, ib-Flat Shallow and Champion series car subwoofers. Each new subwoofer was reinforced with an application of basalt rock speaker technology in the cone production process to deliver the essential low bass frequencies to make music come alive for an enhanced in-car sound experience. The subwoofers adopt a new sophisticated cone design that not only looks sleek, but also reinforces the structure to handle increased power. The TS-W3002D4/2 (12-inch) and TS-W2502D4/2 (10-inch) from the Champion Pro Series line are available in both dual 2-Ohm and 4-Ohm versions and start at a suggested price of $280. The ib-Flat Slim Subwoofers start at a suggested price of $200. The Champion Series Subwoofers start at a suggested price of $120.
