About the Infinity Kappa Perfect 600

Put Perfect sound in your car
Put Perfect sound in your car
Infinity's flagship Kappa Perfect Series speakers look so good and feel so solidly built that it's a shame you probably won't lay your eyes on them again after they're installed, but it's a small price to pay to experience unrivaled audio in your vehicle. This Kappa Perfect 600 6-1/2" component system is a heart-and-soul Infinity creation, utilizing the very best technology and materials available to their engineers.

Add the optional Kappa Perfect 3-1/2" midrange speaker to this system and change the crossover settings with the flip of a switch
High-definition tweeters
Prepare to hear nuance and detail in your favorite music that you never knew was there. Infinity uses edge-driven polyimide dome tweeters to achieve a frequency response up to 30,000 Hz. The "edge-driven" design creates a larger tweeter that handles more power and delivers smooth response way down into midrange frequencies as well. You'll hear a more clearly defined soundstage where you can picture the placement of every instrument.
Tweeter mounts included
While installing tweeters can sometimes prove challenging, Infinity includes versatile hardware for surface- or flush-mounting, making the job much easier in most vehicles.
Carbon fiber woofer with Plus One+ technology
Infinity uses a carbon fiber woofer that weighs less than traditional materials, so you don't need a ton of power to drive this woofer, but the oversized voice coil certainly allows for awesome power-handling if you're driving this system with an amp. Infinity's Plus One+ woofer technology extends the cone right up to the edge of the basket, giving you more surface area than with most comparable speakers. A bigger cone means more bass to complement the superior high-frequency response. The included external crossovers send the appropriate frequencies to the tweeters and woofers.
Want a 3-way Kappa Perfect system?
Infinity makes it easy to turn this Kappa Perfect 2-way component system into a 3-way system with the addition of optional 3-1/2" midrange speakers. Simply flip the switch on each Kappa Perfect crossover to a 3-way system configuration for a well-rounded sound. These speakers are sensitive enough that you can power them with an aftermarket stereo, but you'll get your best results feeding them plenty of power from an outboard amp — up to 100 watts RMS.

Features
Plus One Woofer Cones: The Plus One woofer cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and a significant increase in efficiency.
Terminals: The woofers' input terminals are set screws that will accept up to 14 gauge bare wire.
Woofer Size: Without an adapter, the woofers fit standard 6-3/4" applications. They will also fit in standard 6-1/2" speaker openings, but do not use the standard 6-1/2" speaker bolt pattern. In order to install them in standard 6-1/2" speaker openings you must drill new screw holes. If new holes are drilled in the mounting surface of the car, no bracket is needed. If drilling in the car is not an option, the included brackets can be used, which have standard 6-1/2" mounting holes, the Ford non-symmetric four hole pattern, and other 6-1/2" and 6-3/4" patterns. When using the brackets the depth becomes 2.643" and the mounting height becomes 0.77".
Tweeter Mounting: Using the included housings the tweeters can be flush mounted or surface mounted. The tweeter can pivot in the flush mount housing, so it can be directed to optimize imaging.
Tweeter Dimensions:
Flush Mount | Surface Mount | |
Mounting Height | 0.473" | 1.33" |
Mounting Depth | 1.383" | screw depth |
Frame Diameter | 2.661" | 2.25" |
Cutout Diameter | 2.125" | N/A |
Crossovers: The crossovers can be set to 2-way (the default position, for use with the included woofer and tweeter) or 3-way (for use with the included drivers plus the optional Kappa Perfect 300M midrange, sold separately). Each crossover also has a tweeter output level switch (choose between high and low output). The inputs and outputs are screw terminals that will accept bare wire or spade connectors up to 0.275" wide. There are four mounting holes in the base of each crossover.
Crossover Dimensions:
- Length: 5-1/2"
- Width: 7-15/16"
- Height: 1-5/8"
