speaker break-in, how loud?


I have a pair of B&W 602's that I have had for about 2 months now. When I was breaking them in and now when I listen I only play them a little louder than I would have the TV.(courtesy to neighbors)
Should I play them louder to truly break them in? Will they not be able to handle it a few years down the road if I do turn them up really loud?

Any idea how long a hybrid Dynamic/Electrostatic speaker would take to properly break in, specifically Martin Logan EM-ESL's?
Have any of you taken apart a speaker driver to see what's in there? Surrounding and supporting the voice coil, you'll see the "spider". Think of it as the other "driver surround".

Typically, this is made from epoxy-saturated cloth, and pressed into shape. Over time, the spider develops micro-fractures that makes the spider more pliable. One of the reasons you're not recommended to "break in" a speaker with a single tone (sine wave) is you want micro-fractures to occur throughout the spider to support the entire bandwidth of tones the driver will be asked to reproduce.

The spider is far more (but not always more rigid) rigid than the typical foam / rubber surround simply because of the mass of the item - the voice coil - it's supporting.

Yes, yes...and you're "breaking in" the copper in the binding posts as well. That is...if you believe in "speaker break-in".
