How and why to break in your new speakers
This is a video regarding the concept of breaking in a new pair of speakers and what the benefits are of doing so.
The theory is that during the first several hours of use the speakers won't quite be to their maximum potential and that they will sound better after an initial break-in period has been performed.
This deals with moving parts of the speaker that haven't necessarily been moved before like the spider and surround and the rigidness of the internal components.
