Pioneer TS-A1688S - 6.5" 4-Way Coaxial

Upgrade your vehicle’s sound system with the Pioneer TS-A1688S, part of Pioneer’s premium A‑Series lineup. These 6.5‑inch 4‑way coaxial speakers deliver a powerful 350W maximum music power and 80W RMS, ensuring deep, punchy bass, clear midrange and detailed highs for a full-spectrum listening experience.

The carbon-and‑mica reinforced IMPP™ cone combined with an elastic polymer surround provides quick transient response and high sensitivity, producing warm, natural midbass and rich low frequencies. Pioneer’s signature OPEN & SMOOTH sound concept ensures seamless transitions between drivers and uniform off‑axis performance—ideal for in‑car installation where speaker angles vary.

Included multi‑fit adapter lets you install these speakers in a variety of factory locations without custom brackets. With a broad frequency response (35 Hz–29 kHz) and 91 dB sensitivity, the TS-A1688S brings clarity and depth to every track, making it the perfect upgrade over stock car speakers.
