Thats A good one; let me see Heresy's/ EV 12's, it sounds like when you find a speaker you like you tend to stick with it for a while. I built a pair of Wharfdale 12's and a KLH paper cone tweeter once on a baffleboard at the suggestion of a friend many years ago. That was still one of the most enjoyable speakers I can remmember. Do you think they need to break in at all?
