So last night I really gave these things a work out and had some fun with exploring the dynamic capabilities. In the end I had the feeling that the top end was pushed a little forward and a little over aggressive. They were even a little fatiguing. And I can't stand a speaker with those attributes even in the slightest. I love resolution and detail extremes, but that has to come with balance and smoothness.
So I am thinking about exploring the use of a one ohm or half ohm resistor inline with the tweeters. Right now they have no resistor in the path. I softened the Super 7 in the crossover region for the same reasons. Sometimes a flat response doesn't present itself that way in a room response. And there are ways to move things forward and back in the sound stage to make things arrive just right.
So I have been thinking these need a little tweaking.
But then after playing for about 36 hours straight they smoothed out quite a bit. The lower end and vocals have a lot more body today as well. This is about the biggest change that I have heard in a long time from burn in.
I am still going to explore the effects of tweaking the top end though.
