If you keep reading past the semi-colon you will see that I stated as much.

Now that is just pedantry. Too little power for the selected level is exactly what causes an amplifier to clip, which blows speakers.

To say that a speaker was overpowered by an amplifier implies that amplifiers "push" power to speakers... which they don't: speakers draw power from amplifiers. How much they draw is determined by the level selected and the speaker's impedance and efficiency. Again, (and strangely enough, BigNate and I seem to agree on this) the only way to blow a speaker with too much power is to play it at levels which exceed its physical or thermal limits... which doesn't seem to be the case here. It's simple: speakers don't draw any more power than they need to play at the level you've selected.
