@gammonit_2000 ,
Good point.
Though I would not rush judgement, as the speakers are breaking in.
Though I know some may disagree, I, personally have noticed that speakers really do undergo a degree of change when being run-in when new.
I know of another Agon member, Elizabeth, who owns Maggies.
I would PM her and get her take on the tweeter issue. Otherwise, contact Magnepan directly.
