About the Infinity Kappa Perfect 300m
The Perfect companion
The Perfect companion
Turn your Infinity Kappa Perfect 2-way component system into a 3-way system with the addition of these Kappa Perfect 300m 3-1/2" midrange speakers. Infinity uses a carbon fiber cone that weighs less than traditional materials, so you don't need a ton of power to drive this speaker, 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 allows this speaker to cover effectively down to 150 Hz.
Uber-Infinity
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 speaker is a heart-and-soul Infinity creation, utilizing the very best technology and materials available to their engineers.
Grilles are not included; the factory grilles should be suitable for most applications.

Featured review
These replaced a pair of Focal 3.5"s. I have them band passed 450-3500 and EQ'd via JL Fix D8 and they sound great - not bright at all, good warm sound, very detailed. Very solidly built as well, and easy wire connections.

Features
Midrange: These drivers are midrange, designed for use with the Kappa Perfect 500, 600, or 900 2-way component sets (all sold separately). The crossovers included with the component sets can be set to 3-way for use with these Kappa Perfect 300M midrange.
Note: These midrange speakers should not be used without a crossover.
Mounting: Unlike typical 3½" speakers, the 300M has four mounting tabs. (Most 3½s have two.) When mounting in many factory speaker locations, two of the tabs will need to be removed. The tabs are not scored for easy removal, so specialized tools may be necessary (rotary tool, saw, etc.).
Plus One Cones: The Plus One midrange 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 wire terminals are set screws that will accept up to 14 gauge bare wire.
