Pioneer TS-WX77A Space-Saving Amplified Subwoofer (200W)

This ultra-flat amplified sub (just 8 cm high) will give you rich bass, without invading and taking over the boot of your car.
You can even put your luggage on top of it; the tough polyurethane skin is anti-slip and anti-scratch.
The TS-WX77A has a perfect internal design, maximising the performance of the two 16cm subwoofers inside. With our MOSFET 200W amplifier (known to be small in size but powerful in output) and ‘symmetrical back-loaded horn structure’, the result is a highly efficient system for reproducing bass sound. You’ll hear a rich, vivid and speedy bass; a sound unexpected from such a flat sub.
The TS-WX77A includes a detachable fixing belt and a wired remote control, giving you convenient access to its functions.
