The Pioneer TS-WX300TA is a compact active car subwoofer designed to deliver additional bass without requiring a large enclosure. It combines a dedicated low-frequency driver with built-in amplification to simplify installation into tighter spaces.

The unit is intended for flexible placement in passenger vehicles, accommodating under-seat or small-trunk mounting. It offers standard connections for integration with factory or aftermarket head units and is designed to complement existing speaker systems by extending low-frequency response.
