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

If the woofers were making clanking noises, their voice coils bottomed, the formers may be deformed, and may now rub.

Otherwise don't worry about it.
