I've got LFR's with the new woofers, not new tweeters yet, and they blend perfectly well with my180. Keep in mind from my understanding the primary difference in the new tweeters is the case; not the actual driver ect. So, the end result acoustically should be pretty much identical; with the new tweeters having a much better heat transfer coefficient (due to having a metal case instead of a plastic one) thus allowing them to play louder..
