Those speakers take a long time to "break in." If their not broken in already I wouldn't do anything to them. I just got back from Japan and a guy there said to give them 6 months of regular use before changing anything. If they are broke in, then I would check your filtering options. MHO
Ok, maybe a good advice but i have problem with some kind of music as high female voices and "hard" strings. I think i may break down before the break in??? Beeing a total novice in this format(horn) i have read many places and been given the advice at this wonderful forum that the high freq will be dominating because of the construction. Anyway its useful to know the time taking to break in and you may have the right answer. Thanks Kane
