Most of us here, myself included, feel that the concept of "break-in" for speakers and, especialy electronics, is a myth. IMHO most folks who experience break-in are actually breaking in their ears and brain, adjusting to the vastly superior sound of their Axioms. It can take a little getting used to, especially if you are used to boomy bass, distant midrange, and inaccurate highs.
