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.
• Extended voice coil,
dual spider design for
increased linearity and
high excursion
• 4-layer, copper
voice coil
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.
