If playing at this volume causes the speaker to exceed its thermal or physical capacities (i.e., the amount of heat it can dissipate, or the distance the cone can extend), then the output sound is distorted and the speaker ultimately fails.
b) your amp can not supply X watts: the amplifier attempts to supply the amount of power that the speaker is drawing, but can not. This causes clipping, as the electrical waveform from amp to speaker has its peaks and troughs squared off. The output sound is compressed and the speaker ultimately fails.
The key bit that many people don't get is that the speaker is the component that determines how much output power (i.e., wattage) is drawn from the amp.

by your theory, If I hook up a sub that is rated at 1000 watts rms to an amp that is rated at 25 watts rms, The amp will instantly clip, and blow the speaker?? Total BS Unless I've been doing something wrong for the last 30 years.... Clipping..yes, Overdriving.....Yes, too little power, not a chance.
