how to avoid breaking speakers
#11
so if i try to make sense of all this, basically if you are going to put your system very loud then you better underpower them so you dont put enough power to blow them up even though they might distort. If you are into SQ you overpower the speakers to control them better but you cannot krank the volume in distortion. SO if i listen to music medium-loud but not ear poping during a 5 hour trip, powering my speakers 120w and they are rated 60w rms i should be ok? I know this will sound bad but the GUYS AT THE SHOP told me not to worry (of course they wont pay if it breaks...) although i would not go there again if they lied... and if they told me my speakers could not survive 120w then i would have bought more expensive ones that have higher rating... It is a confusing topic

it's all the same in the end, as far as the drivers concerned.

it can be shown with asymetrical program material (which I guess isn't uncommon) one rail will clip more then the other... over time this could be considered a DC potential.... But a clipped wave or even a square wave is still very different then DC power.......

Let me know if this makes sense

EDIT: I'd like to add a few things.
High peak power, may cause the cone to move too far, thus Mechanical failure sets in. too much RMS power over time will cause Thermal failure...
you can play a clipped signal into a driver for as long as you like without any damage whatsover, as long as it's at a low enough volume for the driver to dissapate the built up heat, and the cone doesn't extend past it's limits.
