I have these and am currently trying to get an amp for them. But, I have heard them in several cars and they sound amazing.

Edit: I thought it was the pro. I haven't seen these but, I can look into it for you.

I have them.

I'm not going to say one way or another because I'm not totally happy with the sound, but I think it's a matter of my amp and install. I'm going to replace the cheapie Hifonics I have running them now (passive) and try to figure a way to get more a bit more bass out of them.

Right now they're installed on my door panel with deadener around them, but I think I'm going to try glassing the backside of my panels to really deaden and strengthen them up.

The tweeters sound good but I'm getting a buzzing noise (almost like some of the bass plays through the tweets) so I'm going to rewire/reground some stuff and move my crossovers to see if that helps.
