Speaker Burn In...

This issue is exactly why many seasoned listeners buy used speakers. Some new speakers take hundreds of hours for proper break in, and even longer periods, the larger the driver.

mmmmm... I would say seasoned listeners buy used to save money, not to avoid break in.

i would say the more you play the speakers the more they wear out as they are mechanical devices, the more the cones or diaphrams move in and out and flex-the spiders and the surrounds wear out. i dont believe in burning in a speaker...they just wear out...my speakers sound the same as when i purchased brand new, that they do now 20 yrs later.

It seems most used speakers for sale on Audiogon are advertised as having low usage/hours. This contradicts the subject of the need to burn-in speakers, which also seems common on Audiogon.

Absolutely can`t agree with Ditusa. If diaphragms movement flex-the spiders then these are not made from optimum material. I can`t actually imagine a speakers like this.
I know that some speaker manufacturers burn in the drivers already in factory. Maybe your experience is based on some of these brands.
Of course speakers wear a bit out as they are mechanical devices but they also need to run in like most other mechanical devices. Like cars for example.
In my experience speaker burn in makes tremendous difference.
