Summary: These speakers are the best bang for your buck. Plain and simple. You are taking in top of the line with these speakers. Although there is a new series from Infinity "Kappa" these "Reference" series are no joke. Forget Pioneer and Sony, these 6x8 are by far the best.
Summary: I have never owned 6x8 speakers until recently. I bought a Ford Taurus that had four of them and it needed an upgrade. I started off with a JVC head unit and then I picked up some Pioneer 3-way 6x8s and installed them in the rear deck for some bass response.
Summary: 6x8 Speakers based on dimension should be very bassy and not able to hit high frequencies well. On top of that, the fact 6x8 speakers are not common, they tend to be neglected for features. The 6822cf reference speaker from Infinity changes all that.
Summary: Clean sound, crisp highs, good bass response and couples well with a 8" bass tube. This is my 2nd pair and I don't think you can buy another speaker this good for this price. I would highly recommend! Infinity is a solid performer!
Summary: I have an 07 mazda cx7. The factory system was ok but did not have good highs. I added a subwoofer and needed the crisp clear highs that these speakers provide to complete the mods i made to my radio. These speakers definately sound great and i only have them hooked up to my factory radio.
