So if I turn the knob on my a/v receiver all the way up, my speakers won't blow out? I'm obviously not going to try it, but my understanding is that they would get damaged. To prevent this, I set a maximum volume on the receiver's settings to the loudest I'm practically interested in, given the size of the room and such. But that probably means I'm capping my volume a good bit below the guaranteed safe level, which only the speaker manufacturer is really in a position to know.
