which series JL, ZR series, they're quite good. CDT is always a good choice and I'm gauging interest on the amp/speaker combo for a full CDT set. Also depending on budget look into Dyna too.
I have a pair of the Jl XR components and they are a really nice set of comps. they are very clean sounding and the tweeters are not harsh at all. it depends on your budget but i would highly recommend the JL XR's
