Infinity Primus 503CF — Primus Series 5-1/4" 2-Way Component Speaker System (Pair)

Harman’s patented Plus One cone design increases cone area by up to 35% over comparable speakers in its class, providing greater radiating surface. These Infinity Primus speakers use edge-driven silk dome tweeters to extend the high-frequency range and preserve the subtle detail in your music. The compact enclosure and low-profile design make installation straightforward in tight spaces, allowing the speakers to fit more vehicles without cutting or other modifications. Super-rigid, vented baskets help cool the voice coils for improved reliability; as the cone moves through its stroke the vents wick heat away from the motor structure almost like a fan. Each Primus model is carefully tuned to deliver the consistent Infinity sound signature.
