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.


Direct Fit OEM Upgrade

The TS-A879 is a 2-way coaxial 3-1/2" speaker. Its carbon and mica reinforced woofer cone stands up to the harsh in-car environment while providing natural sounding tonal qualities with an OPEN & SMOOTH transition to the polyetherimide Tweeter.


Easy Installation

This speaker is designed as a direct OEM speaker replacement in many vehicles including Toyota, Dodge, Chrysler and more.


High Quality Audio Capacitors

The inline audio quality capacitor is designed as an 850 Hz HPF or High Pass Filter. An HPF allows only higher frequencies above 850 Hz to the speaker. This protects the TS-A879 from high power low frequency damage.



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.


Learn Which Speakers Fit your Car

Listening to your music is a big part of enjoying your drive to the fullest. By replacing your factory 2-3/4 or 3-1/2” speakers with Pioneer’s 2-way coaxial speakers, you can recreate your music with better clarity and improved range of sound. Both TS-A709 and TS-A879 speakers are designed to allow easy OEM replacement in many vehicles including Toyota, Dodge, Chevrolet, Chrysler and more.
