View Full Version : Infinity Kappa 60.7's versus Reference 6020cs?

Can someone tell me if there is a significant difference between these two speakers?

I listened to the Kappa system and liked them, but the Reference are quite a bit cheaper. I am considering two pairs of the winner in the cab of my 99 Dodge Quadcab pickup. I am running a Sony CDX-F5500 head unit and will be adding a single 10" sub (Infinity Kappa 104.7w, 2 Ohms) and a Crunch PZI-550.5 amplifier.

I'm not looking to blow the doors off the truck, just looking to get some clean sound to deaden the rattle of my Cummins diesel.

I got the kappa's and they are 2ohm... so they will squeeze a lil more power out of your amps.

some people say they are too bright, but with my crossover I can controll all frequencies, so they are perfect to me. I got the kappas and 4" fosgate power speakers in my doors.

The same speakers are in the back, I gotta have my music in SURROUND.

Both the Kappa 60.7cs and the Reference 6020cs are 2 ohm speakers. I have heard the Kappa's referred to as "harsh," in regards to their tweeter sound, but how are the Reference series? I'm also wondering if two sets of the Kappas in my quadcab might be too much. The rear speakers are 5.25", but can accomodate a 6.5". Maybe sticking with the stock speaker size in a coaxle might be a better choice???
