The Infinity Primus 693C is a 6×9 two-way component speaker system that pairs a Plus One polypropylene woofer with an edge-driven silk dome tweeter for improved midbass and detailed high frequencies. The design includes a vented basket for cooling and a competitively tuned response for automotive audio use.

The package includes two speakers, two tweeters, two in-line crossovers, grilles, mounting hardware, and adapters for common installations. These wired component speakers are intended for installation in vehicles with compatible 6×9 locations or custom mounting locations and connect through the supplied crossovers and speaker wiring.
