Summary: I have no complaints about these speakers. After hearing the low end Frostgates, I came to the conclusion that the only thing better than a Frostgate is a Frostgate. I was right, these speakers are freakishly awesome (fawesome). I use them in conjunction with a sub and the head unit has a high pass filter option so I don't really hear the bass on them due to settings but they never distort. I also have them connected to a 2 channel 350 Watt maximum output Kenwood amp.
Conclusion: Really neat how they mount the tweeters separately from the woofers, unlike common 2 way coaxial speakers. Seem to have pretty good punch to them, take a good amount of power without distorting. Really need to feed them power to get their full potential out.
Conclusion: These speakers are great! I bought them for my brother and they sound far better than my Infinity system I had recently put in my own car! Definitely get these speakers! The Rockford Fosgate Subs are also as good as you can get! Buy Rockford Fosgate if you are truely tone picky like me.
