After 24 hours, I stepped in to listen as Dire Straits continues to play. In short order, I knew that the peakiness is still very much there with one change to note. It have spread to a wider peak rather than a sort of one note peak. This may or may not be good news, as i have not much experience with breaking in drivers. Having said that, I did break in a set of Audio Nirvana drivers a couple of years ago that were absolutely unlistenable out of the box. In a few hours they had a dramatic change that saved them from being sent back to the dealer. In time they sounded quite good for a 12" single driver affair. I sold them to a church where their sound was met with enthusiasm compared to the horrible sound that preceded them.
I hope to have the same experience here, even if I only come close to the original sound of these drivers when brand new.

At a bit under 72 hours, there are some significant changes. That being said, I am not to the goal of getting rid of the harshness that predominated the recent sound from these speakers. The bass is more than I expected, so that is good. The treble has come back close to what I liked hearing from these drivers in the first place. The mids are not as compressed, and yet have a bit of hardness to them. I do take the D class amp into consideration when making these notes. I am opting for at least one more day of running these in. Past that, I don't expect to hear much better than they are already.

It has been some time since i have listened to the speakers. Last night, i listened to Allison Krauss/Robert Plants album, "Raising Sand". I wouldn't use such an album to evaluate sound as a foundation anyway. In this case however, there were some changes most notable in the bass. It came out in the bass drum kicks that had depth. Better yet, the depth was defined. I have no doubt that lower part of 40-50hz was being reproduced with a definition that i have never heard from these drivers. Secondly, and quite welcome, was the lower midrange. Fuller would be the term that comes to mind, with more definition needed. The actual middle of the midrange that bothered me in the past only came light when Plant was pushing his roots up from the Zep days. In other words, it is almost intended that the music has an edge to it. Having said that, Krauss had her influence in the writing of tracks as well, and there was a slight edginess to her voice. I had to admit to myself that my hearing is particularly picky about such a thing, and that I doubt that I have all but rarely ever heard a midrange that I am totally comfortable with. The exception seems to be with some headphones, but again, it is a pretty fine line. Lastly, it is the treble that I miss most about my hearing. I know that it is there, but I am just not able to hear past 12kz or so. this really gives music the expression that I enjoy so much. I have to say once again, I do better with headphones in this case, but not enough to satisfy what I miss.
All told, I am much happier with the drivers, and am enjoying the music more than the evaluation at this point. That is a big step when you can put down the tablet, and stop taking notes.
