About the Infinity Kappa 20mx

3-way your Kappa components

Expand your Infinity Kappa Series component system with this pair of Kappa 20mx 2" midrange speakers. The Kappa glass fiber cone will hold its shape when the power's cranked up, giving you a robust midrange presence. Glass fiber weighs less than traditional materials, so you don't need a ton of power to drive these speakers, but oversized voice coils certainly help them handle up to 65 watts RMS.

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. The extended cone also allows this speaker to cover effectively down to 550 Hz. 

Crossovers included

Infinity includes bandpass crossovers for excellent tonal balance when incorporating these into a 3-way system.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
I Chose these speakers because I will be upgrading my speaker system in 2015 Camaro and due to space available I believe these will work. And they are a match for the next set of Kappas I will buy from Crutchfield. [ Master  Mar 18, 2019 ]
A
Great brand! And size needed. [ Willie  Feb 03, 2019 ]
A
I have a pair of Infinity Kappa 60.11cs components. The driver is very good at mid-bass to midrange but is lacking in upper midrange. So i'm adding these to help fill in the upper-midrange and turn it into a full 3-way system. [ Guest  Dec 16, 2018 ]
A
to convert into 3 way system [ richard  Dec 11, 2018 ]
A
3 way or no way baby! [ Tony  Nov 14, 2018 ]
A
I have a pair of Kappa 6x8's in my car and they sound great plus I wanted to keep every thing as matched up as possible. I purchased the kappa 20mx because of the great reviews, cheaper than the ebay price. [ THOMAS  Oct 04, 2018 ]
A
I wanted a small midrange that should be usable in my a-pillars to go with the Infinity tweeters I have. [ RODNEY  Apr 27, 2018 ]
A
Needed a decent 2" midrange [ Brandon  Dec 26, 2017 ]

Q
Since these integrate with the component crossovers, do they need a separate power source?
[ Mat  Dec 16, 2018 ]

A
I believe there is separate crossover included with the mids that connects to the woofer.
[ Timothy  Dec 16, 2018 ]
A
no they don"t the power goes through the crossovers.
[ Leslie  Dec 16, 2018 ]
A
No. The 20mx comes with its own "crossover" type box, but it still runs/splits off the same speaker wiring.
[ Kristofer  Dec 16, 2018 ]
Q
Any chance you can provide the measurements of the speaker brackets?
[ Mark  Jan 03, 2018 ]

The backing plate it mounted with 2 ears which the 2 mount holes are 3.90" center to center. The outside diameter of the plate is 3.25" except for the 2 mounting holes which the overall for those is 4.40" The hole for the driver is 2.60" You will need 1.40" for mounting depth. Hope that helps. Awesome mids !
[ Thomas  Jan 06, 2018 ]
Q
Would this fit in a 2007 Lexus IS250 w/o Mark Levinson? The hole in the door is something like 2-1/2 inch for a stock mid.
