Infinity Perfect 600, KAPPA Perfect Series 6 1/2" Component Speakers System
New Primus speakers feature our patented Plus One™ polypropylene woofers which feature more radiating cone area for increased output and edge-driven tweeters for better high frequency dispersion. Speakers are super clear at the top with vocals, horns and strings and deliver big bass with plenty of slam. Long story short: superior sound top to bottom. True 4 ohm architecture gives the amplifier room to reach peak power for increased depth and detail. There are seven Primus models for easy installation in any vehicle, whether it's a truck, compact or limo. In addition to passing demanding reliability and environmental testing, all speakers are individually voiced by some of the world's best transducer engineers to authenticate the Infinity sound. It's not a coincidence that Infinity is one of the world's top-selling car audio speaker brands.
Patented Plus One™ Polypropylene Woofers
Polypropylene cones with up to 35% more radiating cone area than other cones in the same class provide higher sensitivity, increased low frequency output and better tonal balance. Hi-roll rubber surrounds using automotive grade materials result in cleaner reproduction and higher durability whether it's easy listening or time to show and shine.
High-definition, edge-driven 30kHz polyimide tweeter
Lightweight yet rigid, the polyimide tweeter in Kappa Perfect component speakers reproduces high frequencies with meticulous detail—an Infinity hallmark. This not only brings out more of the music’s true character, it also improves sound staging capabilities.
Switchable 2-way/3-way crossover
Kappa Perfect component speaker systems include a unique, switchable crossover that lets you select either a 2-way or 3-way system configuration with the addition of the Kappa Perfect 300m midrange speaker. The crossover features weatherproof housing, so it can be mounted in a door.
Sleek industrial design
Combining brushed metal with premium finishes, Kappa Perfect speakers and crossovers are as pleasing to the eyes as they are impressive to the ears.
