Infinity Perfect 500, KAPPA Perfect Series 5 1/4" Component Speakers System
What happens when leading audio engineers with world-class resources develop uncompromising component speaker systems without cost constraints? Audio perfection. Introducing Kappa Perfect, Infinity’s flagship line of super-accurate, super-high performance speakers. Kappa Perfect component speakers deliver high power handling, high SPL capability, and unparalleled response. They also feature high-end industrial design and available three-way configuration. With just the flick of a switch, you can transform a 2-way system into a 3-way system by adding the Kappa Perfect midrange speaker. Any audio company can aspire to perfection. But only one with Infinity’s engineering, manufacturing and testing resources can achieve it.
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.
