The new Primus speakers feature our proprietary Plus One™ polypropylene woofers that feature a more radiant cone area for increased output and edge-driven tweeters for better dispersion of high frequencies. The speakers are super clear on top with vocals, trumpets and strings and deliver big bass with plenty of punch. To sum it up: superior sound from start to finish. True 4 ohm architecture gives the amp headroom to reach full power for greater depth and detail. There are seven Primus models for easy installation in any vehicle, whether it's a pickup, compact or limousine. In addition to passing rigorous environmental and reliability tests, all speakers are individually voiced by some of the world's best transducer engineers to authenticate Infinity sound. It's no coincidence that Infinity is one of the best-selling car audio speaker brands in the world..PZAMORE SPECS
