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.

Grilles are not included; the factory grilles should be suitable for most applications.

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.

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"

Q
what frequency are the tweeters crossed over at?
[ Doug  Apr 17, 2017 ]
1 answer
A
I'm afraid the crossover points are not included from the manufacturer. For more details on that, you may want to contact Infinity directly--their support number is 800-553-3332.

Q
can the perfect components be run at 2 ohms?
[ scott  Jan 11, 2017 ]
1 answer
A
The Infinity Kappa Perfect 500 are 3.5 Ohm speakers so, no, they will not present a 2 Ohm load to your amp.
