David,
Fascinating that you blew a tweeter. You must have been cranking it.
An extra note that I forgot to mention in regards to the research I've been doing on near-field monitors. Even though I'm looking for what I hope will be "objective" and "honest" sound from monitors, what appears to be the scene amongst people commenting on monitors is that they are very personally attached to their opinions about their monitor choice.
Meaning to say, it seems that whichever set of monitors that someone selects (and there are a good number of choices), that person will likely think they are great and the other monitor selections are less great. I've seen quite a few posts or review notes where the person praises their own set of monitors and highlights some lesser quality of another monitor. It seems instead of there being an "honest" and "objective" set of monitors out there, instead there are monitors that appeal to your ears for one aspect or another, and comparative listening is good to find a set for your personal tastes.
With all that said, and without demeaning other brands, I'm leaning toward the KRKs and thinking that my mixing will get better as a result of having them versus what I do now, which is mix entirely using headphones (which I know is a bad thing).
