Interesting-- so this would lead to the conclusion that speaker damage is

1. Pretty much all-or-nothing, and
2. Sometimes the damage only shows up when the speaker is driven hard?

Or, put in the negative,
1. Very rarely does subtle-yet-meaningful damage occur, and
2. speaker damage very rarely affects moderate listening levels?

A friend just walked in and before he saw what I was doing, he said "You're out of your element! You have no frame of reference!" Is he right, or is what I said feasible?
