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).

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.
