About: Pioneer TS-A120D4 A-Series 12" Subwoofer 

TS-A120D4 12" subwoofer handles up to 500 watts RMS while pumping out loud, clean bass. This sub features an injection-molded polypropylene cone that's impregnated with glass fibers and mica for exceptional precision and strength. A butyl rubber surround supports the woofer during cone excursion so you'll get accurate, hard-hitting bass notes even when the music's turned up loud. 

Easily Upgrade to High Performance

The Pioneer A Series speaker 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. Pioneer’s OPEN & SMOOTH sound concept provides a seamless and smooth transition between the midrange and tweeter drivers and delivers uniform off-axis frequency response optimized for automotive applications where one or more speakers are often aimed away from the listeners’ ears. The A Series lineup expands flexibility and improves acoustic performance. The integrated inline crossover network allows for increased installation flexibility without the need of an outboard module. Included with the Pioneer A Series, are multi-fit installation adapters and tweeter mounts (when applicable).

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.
