Bigger cone, stronger bass, more power.

Discover the Pioneer TS-A Series of shallow component subwoofers. Designed with carefully selected materials to improve bass response, these subwoofers are the perfect match to be used alongside the TS-A Series of speakers. If you are looking for a sound upgrade combined with easy installation, then look no further than the TS-A Series.


This 25cm subwoofer is just 8.7cm deep and has an oversized cone that produces louder bass than ever. Boost your car audio with 1200 Watts of pure, superior bass without losing too much space in your car.


Designed for enclosed use, the TS-A2500LS4 is fitted with a single oversized cone structure with double spiders to increase power handling and generate a more accurate, louder bass. The single cone helps keep the overall moving mass down at manageable levels, which is extremely important for efficiency and sound quality reasons.


A typical sub uses a damper to control the woofer’s cone excursion. Our double spiders are more efficient as they need less power to move the cone while producing superbly detailed and low distortion bass.
