First of all, I would like to say that I love this forum. Currently I am running CDT 6.5 Eurosports and I hate the low end on these speakers other wise they are great. I was not planing to start looking for a new midbass until I saw this clip http://www.realmofexcursion.com/videos/BostonAcoustics/pro6.5.1.wmv and now I am on the hunt . I have been looking into the Extremis, Lotus, and the old Boston Pros (the ones in the clip). I am loving the low end specs on these speakers but how much high end range and clearity would I be giving up? I dont want to pay over 215 for both speakers shipped. By the way I will be selling my eurosport set.
