Pioneer TS-WX210A Compact 8" Subwoofer Kit The TS-WX210A focuses on functionality and performance. Use this 20cm sub vertically or horizontally: it takes up a minimum amount of space in the boot or virtually disappears under a seat. But its performance punch is an attention-grabber. A quality MOSFET 150 W amplifier provides powerful bass, while a cabinet-reinforcing aluminium die-cast heat sink is responsible for top sound performance, free of distortion. A wired remote control is included for easy gain, phase and LPF tuning.
