HELP - How Hard is to Blow a Bass Driver


As I came home I see my little brother and his friend BLASTING a Prodigy song in my listening room. I don't know the song but it was about 1 MIN. of just full loud annoying bass only (the kind you hear in Honda Civics while the liscense plate is rattling). As I ran into the room to lower the volume I saw the Driver shaking like CRAZY. Not "in and out" motion but more like shaking erratically all over the place.
Amp is the Exposure 18(70 watts rms)
Speakers are the PMC Fb1
Volume at 12 o-clock

I'm concerned that there might be damage to the Drivers. I can't hear any damage but could there be internal damage (coils)that might show up later on? Any way to test for damage?

Thanks for your help as I am stil in a cringing state

I had my monitors clip when I used one section of a bi-wired speaker cable (I left the other pair speaker wire on the floor with the leads up in the air) and turned the volume up fairly high.

My amp was a 180 watt at 8 ohms. My monitors were 4 ohms.

Can someone please explain to me how this could happen is my amp is POWERFUL enough to handle such loads from my monitor?........
