INFINITY PRIMUS 693C - Primus Series 6"x 9" Two-Way Component Car Speakers

Infinity Primus 693C | 6″×9″ Component Speaker System | 80 W RMS | 93 dB SPL

The Infinity Primus 693C is a 6″×9″ component speaker system thoughtfully engineered to deliver clear vocals, crisp cymbals, and solid bass in car audio applications. Featuring Infinity’s patented Plus One+ polypropylene woofer cone and edge‑driven silk dome tweeter, this two-way system offers elevated performance and vehicle compatibility. With a vented basket design, these speakers stay cool under load while offering efficient output even on factory head units—no extra amplifier required.

Rated at 80 W RMS (240 W peak) and achieving approximately 93 dB sensitivity, the Primus 693C delivers excellent output and efficiency. Its low 3 Ω impedance helps maximize sound from stock radios and aftermarket stereos alike.

Designed with a standard 6″×9″ form factor, external crossovers, and included mounting accessories, the system is ideal for clean front-stage imaging in a wide range of OEM upgrade and aftermarket installations.
