Key Features

12" 1400w Champion Subwoofer with Dual 4ohm Voice Coils - Pioneer TS-W311D4

More bass. More power. Greater flexibility.
Get powerful, punchy bass in your car – from the pedigree of world record-breaking subs.

The TS-W311D4 features a combined IMPP cone, which makes the body ultra-rigid yet lightweight, giving you low distortion and powerful bass at high sound press levels.
This subwoofer brings greater flexibility too. With a 4Ω dual voice coil, you can opt for a 2Ω or 8Ω set-up (provided that there is correct power matching between the sub and your amp).
