The Pioneer TS-A1300C 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 the flexibility and improves acoustic performance. The integrated inline crossover network allows for increased installation flexibility without the need for an outboard module. Included with the Pioneer A-Series, are multi-fit installation adapters and tweeter mounts (when applicable).
