The Infinity Primus Speaker Series are an easy and affordable upgrade to your lackluster factory speakers. We’re offering them in two new configurations, which are designed to fit stock sizes and give you a custom-fit look. Featuring Plus One™ woofer cones and edge-driven tweeters, you’ll experience the breathtaking sound that has made Infinity one of the world’s top-selling premium car speaker brands.
Product Features:
  • Plus One™ Woofer Cones
    Harman’s patented (US patent #7,548,631) Plus One™ polypropylene cones provide more overall speaker-cone area than other cones in its class — the result is higher sensitivity, increased low-frequency output and greater musical character.
  • Edge-Driven Tweeters
    Soft dome tweeters deliver a smooth high-frequency response and an increased power handling for highs and mids, which equates to more lifelike sound from vocals, cymbals, brass instruments and pianos.
  • Frequency Response Up to 21kHz
    Hear what you’ve been missing — the Infinity Primus Series offers a frequency response that delivers the full-range response associated with exceptional sound.
  • Individually Voiced
    For most brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That’s not the case with Infinity, the world’s top-selling car speaker brand. We don’t only listen to our speakers against the competition — we voice them against each other to ensure each line has the consistent Infinity sound signature car audio enthusiasts have come to know and love. This is just part of an extensive development process undertaken by some of the best transducer engineers in the world to provide the finest listening experience at any price point.
  • Two More Configurations to Fit Most Vehicles
    The Infinity Primus Speaker Series are designed to fit most vehicle speaker openings without cutting or modification. Simply put, it’s the easiest way to boost your car’s sound performance.
  • Affordable Pricing
    The Infinity Primus Series are all designed to give audio enthusiasts more boom for the buck — while they maintain a conservative price point, there is never a compromise in sound.
  • OEM-Level Reliability Testing
    Infinity tests every speaker design to the same rigid specifications as the automakers, subjecting them to extreme conditions that would break lesser speakers. We freeze them, bake them, shake them, blast them with ultraviolet light and drive them at full power for days to make sure your audio investment lasts for years.
