Sorry, I didn't have much time to type a better response, and I can't either at the moment. Just enough time to say: I use Infinity 6500CS in my daily driver and the sound quality is superb!
JBL aren't to shabby either, I've heard some decent tones from them.

I agree with Stan the infinity series are excellent. However they are perhaps not as forgiving as other makes when it comes to the quality of the audio source so make sure you have a top h/u and or amp.
