12” pre-loaded bass-reflex (ported) subwoofer system
Passive (non-amplified) design provides system flexibility
Glass fiber and mica interlaced Injection Molded Polypropylene (IMPP) cone construction
Butyl rubber surround and polycotton / cotton dual spider for strength and linearity during high excursion
Oversized 60 oz double stacked magnet and vented pole yoke for increased power handling
Smooth and seamless integration with Pioneer A-series full-range automotive loudspeakers

Pioneer’s A-series sound design purposely matches the subwoofer and full-range loudspeakers to provide seamless and smooth sound characteristics with dynamic, high impact bass that lets you hear and feel the music.
Linear, Balanced Motion
Linear, balanced motion in both the forward and reverse directions of cone movement is critical to accurate reproduction of recorded sound waves. Careful engineering of the entire motor structure and suspension system (voice coil, magnet, surround and spider) is required maintain a high level of linearity, even during high output / high excursion transients.
