Noise Level is important for high efficiency speakers. Increasing power doen't necessarily increase noise. A 5 watt amplifier can have a higher specific noise level than a 500 Watt Amplifier. But theoretically can handle 20 dB wider dynamic range. While most recordings don't have minimum to peak levels of more than 40dB some recordings can span 70dB or so... and live music can span 80dB or more! A snare rim at 10 Feet away can have a peak level of over 125dB!
90dB/W/m loudspeaker needs a 500Watt amplifier to score that peak!
a 100dB/W/m Loudspeaker still needs a 50 Watt Amplifier.

That helps underscore why it's so hard to accurately reproduce many dynamic things, what we hear and judge as "loudness" is only loosely related to the dynamic of the signal and for many things perceived loudness is more like a short term average C weighted SPL
