More bass. More power.

The Pioneer Champion Series subwoofers are powerful, robust and can handle high power at high audio levels without losing audio quality.

With Dual Spiders and Motor Assembly as the driving force, they can produce deep dynamic sounds that are in line with the Champion Series name. These models also feature a unique Pioneer Dust Protection design to prevent dust from interfering and reducing the performance and reliability of the subwoofer. Pioneer Champion Series subwoofers ensure precise, deep and rhythmic bass using state-of-the-art technologies , such as a Pioneer-patented IMPP composite membrane material, a strong 3D-shaped cone design and large double-stitched magnets.

When powered by Pioneer's GM-A Series with amplifiers, the Pioneer Champion Series subwoofers can deliver truly powerful, rich, high-quality bass, no matter the sound level .
