In another thread, I read about speakers sounding different as they "break-in".
What exactly does that mean in terms of perceivable sound and how exactly does one break-in a speaker, other than through normal use?
Jeff, when a speaker is new things are kinda "stiff". This makes the sound more trebly and glassy.
After about 40 hours of playing everything has been flexed enough that the speaker sounds "warmer".
Some guys will break-in a speaker on their bench by taking a small transformer and running maybe 6 volts AC into it overnight. This feeds a loud hum into the speaker and you would want to shut the basement or garage door rather than listen to it.
Whatever, the difference is subtle rather than a whack-on-the head type. Most guys just play through it. After all, the speaker starts out sounding good. It just gets better!
