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.
