I am often told that you shouldnt use basses with guitar amps because the speaker "cant handle" the lower frequency sounds, and can blow. I was wondering, what precisely makes a bass amp speaker technically different from a normal guitar amp speaker, and how exactly lower frequencies can "blow" a regular speaker. I am aware that the human ear is less sensitive to lower frequencies, so to get the same percieved volume a greater wave amplitiude is needed, but surely that would only be the same as cranking your guitar amp up to full, and guitar speakers arent usually damaged by doing that... i was also interested in buying some marshall mircostacks, but was told by the shopkeeper that a bass would "blow" them. Is this true, even for such a small amp? And again, how exactly would this work?
