I'd go with Jl XR out of the choices, but for the price range (if you're paying full or in that range) I think there are better component systems out there. I like the Diamond Audio Hex series for the 600 dollar range, and most people will say they like them better than JL's. I like JL mostly for their amps and the W7.
in the end it's up to your ears, and both are great sets. I like the eclipse for their silk dome tweeters. smooth, flat response, and good dispersion angle. makes for good imaging and realistic vocals.. not as bright as tweeters in other sets, but if you're after a flat, accurate sound instead of an inverse bell curve like most people set an EQ for.. the Eclipse are your speakers. They have a similar feel to DynAudio.
