A Series
The highly efficient design of the Pioneer A Series speakers intentionally 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 ensures a seamless transition between the midrange and tweeter drivers, delivering a 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 enhances audio details and improves acoustic performance.
