Pioneer's Champion Series PRO TS-W3003D4 delivers the chest-pounding bass you expect from a 12” subwoofer. Its rugged construction enables it to handle up to 600 watts RMS without a problem, for performance you can count on. This sub offers the versatility of dual 4-ohm voice coils (DVC) and the ability to work in a sealed or ported enclosure, so it'll fit right in your system, no matter what type of bass you like. Improving on conventional designs, the TS-W3003D4 features a dual spider design for improved linearity, a larger pole with thicker wire for more accurate bass, a larger magnet for louder bass, and a reinforced basket for more durability. Designed with dual 4 ohm voice coils, for an 8 ohm or 2 ohm configuration, these subwoofers are capable of fitting into a 0.85 cubic ft. to 1.75 cubic ft. enclosure. The newly designed Champion Series PRO subwoofers are built to produce loud and powerful bass capable of withstanding up to 2,000 watts of maximum power with 600 watts of continuous musical power.
