Discover the new Pioneer TS-A Series range of fine-component subwoofers. Designed with carefully selected materials to enhance bass response, these subwoofers are the ideal complement to the TS-A Series speaker range. If you're looking for a sound enhancement combined with simple installation, the TS-A Series range is just what you need.This 25cm subwoofer has a depth of 8.6cm and a large cone that produces higher bass than ever. Amplify your car audio with 1,200 watts of superior pure bass without losing too much space in the car.Designed for confined use, the TS-A2500LS4 is equipped with a single large cone structure with double spider, to improve power management and generate higher, more accurate bass. The single cone helps keep the overall moving mass low (at manageable levels), which is extremely important for reasons of efficiency and sound quality.A typical subwoofer uses a damper to control the excursion of the woofer cone. Our dual spider is more effective as it requires less power to move the cone, while producing perfectly detailed, low distortion bass.
