Our take on the Infinity Kappa Perfect 300m by Crutchfield's Alexander Hrabe
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.
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.

Infinity Kappa Perfect 300m Reviews
Average Customer Review(s):
Thanks for submitting your review
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.
Mounting: Unlike typical 3-1/2" speakers, the 300M has four mounting tabs. (Most 3-1/2s have two.) When mounting in many factory speaker locations, two of the tabs will need to be removed.
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.

B/c best speaker for what needed and very good price! [ David Nov 27, 2017 ]
Well, this was a chance I took for my Tundra's center speaker in dash. Never been highly impressed with Infinity, but also never owned any...impressions were from friends cars. This speaker was a great compliment to my system, great clean, crisp and nice sound. [ titanium man Jun 29, 2017 ]

To replace a JL Audio C2-350x 3-1/2" 2-way speaker I was having trouble with, plus the higher RMS handling on this Kappa provides me with more options when using my 6-channel amplifier. [ Alexander Jan 25, 2017 ]

6 questions already asked
Yes they would sound much better with suficiente power. [ Pedro Jul 26, 2018 ]
I purchased this for my grandson...He put them in his pickup truck and they have been there ever since, so I imagine that he is satisfied with the speakers. And, he is very particular about anything...hope this somewhat answers the question.... [ Catherine Apr 14, 2018 ]
1 7/8 inch [ kyle Apr 14, 2018 ]
While I, of course, do not have your specific car, I am confident to answer yes they would. They are solid and very capable speakers with great clarity. They've been the best part of my six-speaker upgrade thus far. Stock systems, despite being Infinity, Bose or JBL, always seem to have their limitations. Hope this helps. [ JIM Feb 13, 2018 ]
they scream with the right amplifier [ PAUL Feb 12, 2018 ]
Not sure about vehicle fitment but i installed these in the dash openings of my 13 ram 1500 & it was the biggest improvement compared to replacing all the door speakers, these are the ones that really made the system come to life! [ Michael Feb 12, 2018 ]
This is not a bad speaker, but in my opinion not worth the price. Yes, it will be better than stock, but unless your ram has a very poor stereo system, then the difference wont be huge. If yours is already OK, to Pretty good, these won't help $150 bucks worth. [ James Feb 12, 2018 ]
No they do not. [ Conor Feb 05, 2018 ]
Unfortunately they do not [ kyle Feb 02, 2018 ]
Nothing else comes with these speakers but screws, instructions and some decals. [ Eliasar Feb 02, 2018 ]
I dont think you can purchase just one. They come in a pair in the box. I only needed one as well for my F150 Harley Davidson. Now i have an extra if it goes bad. [ Eliasar Jan 12, 2018 ]
Sorry, no. They are only packaged in pairs. [ Ryan Dec 27, 2017 ] Staff
1 answer I have a 2015 Jeep Cherokee and looking first to replace the two 3 1/2" dash speakers. Stock speakers are rated at 8 ohms, but after-market are typically 4. My questions: 1) for speakers rated for 80 Hz, would bass blockers be needed? 2) would the Cherokee factory head unit not appreciate the 4 ohm impedance? [ Lee Nov 04, 2016 ]
You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with the factory system in your 2015 Jeep Cherokee. They can go over all the options for integrating with the stock system and explore other avenues if you discover this won't work for your application. I hope that helps! [ Larry Nov 09, 2016 ] Staff
