Having just acquired a spankin' new pair of monitors for my home studio, I'm currently in the process of "breaking them in".
Being an inquisitive mind, I started wondering: what is the purpose of this?
For those who aren't familiar with the term: "breaking-in" speakers is simplicity itself and consists in playing music over them for some time - typically 10-20 hours. This period of adjustment in order for the speakers to settle into their optimal working state, that will affect their sound, is recommended by manufacturers and reviewers alike.
NOTE - The studio monitors will take break-in time to achieve optimum sonic performance. Under moderate use, play a favorite album between 15 to 25 hours.
After setting the filters for my room and an extensive break-in period, they became both punchy and percussive in the low end, as well as fast and “airy” in the upper end of the frequency response.
Is this really the case? And, if so: how does it work?
An ideal answer will address the physics involved: does the break-in period affect electronics, the speaker cones, the cabinet, all of the above; as well as the expected changes in sonic qualities following the break-in period. What differences can we expect to hear?
If any studies have been performed, references would be appreciated.
A negative answer ("break-in is a myth", as some claim) would ideally reference studies that demonstrate no measurable difference between "unbroken" and "broken-in" speakers.
