Listen closely and you might hear the woofer and mid-woofer alignment is wonky at first. When I first heard this effect, I thought someone at Axiom messed up. But I kept playing them and it cleared beautifully. The next two pairs were already broken in. My OW were also wonky but I let them play for a weekend while I was out cavorting. When I came back, they were peachy.
