Either I'm imagining things, or my 0300s are sounding much more full in the bass than when I first hooked them up about 10 months ago, and I like it (a lot).
I know some say that what's being "broken in" is the listener's ears as they get used to the sound of the speaker they are constantly exposed to, but I am prepared to believe that the loosening of the suspension and the resulting measurable lowering of fs of the bass driver after a prolonged period of fairly heavy use is actually clearly audible.
At the same time, I am fully aware of just how vulnerable we are to auto-suggestion. I have been badly caught out in the past when an EQ I thought was in circuit was not.
