TS-W312S4

“The Champion Has Returned”

Pioneer’s latest “Champion” series sub-woofers are here. The TS-W312S4 is designed to take the “Champion” Series name to the next level with a range of improvements.

With a light weight/high rigidity cone design, dual layer hybrid surround, large powerful motor assembly and enclosed basket structure, the new “Champion” Series sub-woofers not only look good but will perform even better!

Match with Pioneer’s GM-D Series amplifiers for an impressive in car experience!


Rigid Cone Construction

Combining a large rigid centre cap and lightweight high rigidity cone structure improves output performance and reduces loss. Improved dual layer (elastic polymer & fibre) hybrid surround provides a lighter and more durable surround than traditional rubber compounds.


Powerful Motor Assembly

Combining a double stacked 90oz magnet (26% bigger than our previous model and some of the heaviest in it’s class) with a longer voice coil design, the “Champion” Series sub-woofers are designed for high power handling and endurance!
