Easily Upgrade to High Performance
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.
