Description

Infinity Reference 687F

The Infinity Reference 687F is a high‑performance 6″×8″ 2‑way coaxial car speaker designed to deliver clear, balanced sound with strong midrange and extended highs over standard factory speakers. It features Plus One™ polypropylene woofer cones with hi‑roll rubber surrounds for increased cone area, enhanced bass output, and accurate audio reproduction. The 1″ edge‑driven textile tweeter provides smooth and non‑fatiguing high frequencies, while the adjustable tweeter output level control lets you fine‑tune the treble response based on installation location or listening preference. With a 3‑ohm impedance that combines with speaker cable to present a true 4 Ω load and 93 dB sensitivity, the Reference 687F ensures efficient sound and louder output even from factory head units. Its frequency response spans 49 Hz – 21 kHz, and it handles 60 W RMS and 180 W peak power, making it a solid upgrade for everyday car audio systems.
