About the Pioneer TS-A879

Don't overlook this little speaker

More and more automakers like Toyota, GM, and Chrysler equip their vehicles with 3-1/2" speakers in the dash, and Pioneer has the perfect upgrade. These Pioneer TS-A879 3-1/2" 2-way speakers flaunt surprising power-handling and solid construction. A carbon and mica-reinforced, injection-molded polypropylene woofer adds sturdiness to your sound while the polyetherimide tweeter steps up the detail. Pioneer includes inline high pass filters with high-quality capacitors to protect the speakers from any damage that lower frequencies can cause. Overall, you can look forward to more clarity from your tunes than with your factory speakers.

  • 3-1/2" carbon and mica-reinforced injection-molded polypropylene midrange speakers

Product Research


Overview: Pioneer describes the TS-A879 as a wide range speaker (as opposed to a full range speaker), designed to replace the 3½" speaker used by several vehicle manufacturers. Please enter your vehicle information to confirm fit.

Crossovers: A 6 dB/octave, 850 Hz high-pass crossover is integrated in-line with each included 10" length of speaker wire. The output end of the wire has quick slides that plug onto the speaker terminals; the input end of the wire is not terminated. At the widest point the crossovers measure just under ¾" across.

Power: The 100 watt RMS power rating is valid only when using the included crossovers.

Frequency Response: The published frequency response is 52 Hz to 33 kHz (-20 dB), but the -3 dB point on the included high pass crossover is 850 Hz. (The included crossover should always be used, unless the speakers are actively filtered.)
