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.

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

These midrange speakers are designed to work with the Kappa 60csx and Kappa 90csx component systems which include crossovers that can be switched to 3-way mode. Infinity also includes bandpass crossovers for excellent tonal balance when incorporating these into any 3-way system.

These are sealed back drivers. You can install them anywhere, no enclosure needed.

Q
When running the 20mx in 3way mode with 60csx what is the total impedance?

Hi I returned them. Your best bet is to call their tech support. They've been very helpful to me in the past.

Q
How are these wired into the component speaker setup (Kappa 60/Kappa 90)? I've looked at the instructions and they don't make sense.

The kappa 60 comes with a small cable that plugs into kappa 90 crossover connecting the two crossovers. Then you run speaker wire from the kappa 60 crossover to the kappa 60 speaker. There is a switch on the on the kappa 90 crossover that you put into 3-way position. At that point you are good to go. I've got the 90s with the 60 up front in the doors of my civic. Got 6×9 3-way kappa 93s on the rear deck. Factory radio with an amp adapter then through a massive audio 7 band line driver equalizer which you need if running a factory radio. Then powered up with Infinity Kappa kx400.4 100 watts rms. It is clear, loud and awesome. Two 12s in the trunk to make the bump and rumble of course.
