Infinity Primus PR9610CS 6x9" 2‑Way Component System + PR5012IS 5.25" 2‑Way Speakers — for Dodge Ram

Patented Plus One Polypropylene Woofers: Polypropylene cone woofers engineered with up to 35% more radiating cone area than competing designs, yielding higher sensitivity, stronger low‑frequency output and a more balanced tonal response. Edge‑Driven Tweeters: Edge‑driven tweeters provide broader dispersion and a smoother high‑frequency curve while raising power handling for both high and mid frequencies. True 4 Ohm Architecture: Built with true 4 ohm architecture and low‑impedance voice coils to give your amplifier room to reach peak power, resulting in clearer, more detailed sound with enhanced depth. Durability Testing: Infinity puts these speakers through extreme tests — freezing, baking, vibration stress, ultraviolet exposure and continuous full‑power operation for days — procedures that would destroy lesser units. Individual Voicing: Each speaker is voiced individually rather than using off‑the‑shelf tuning, so both the published specifications and the actual speaker characteristics are taken into account to achieve the signature Infinity sound.
