Originally posted by Progress Ent. While that is true, there also is an issue with running too little power to drive the subs. I can't really explain it, I'll see if I can find the curves the guy from EAW used to explain it to me when I was setting up my club. There is some sort of reverse action caused by the size of the driver magnet vs. the power coming in from the amp that will cause the speaker to blow if it is underpowered.

they could have meant an amp lacking enough power to move the motor efficiently and smoothly enough meaning the mechanics get over stressed an cause damage to the inner suspension workings and cone.

i suppose an 18" driver can have moving parts that weigh up to quarter of a kilo at a guess.. so subjecting it to a unsmooth square/sinewave will certainly be magnified on the stresspoints such as where the cone is bonded to the voice coil.
