Many manufacturers exaggerate their specs. For accurate reproduction, frequency response should be rated within + - 3dB range.

Try finding something that can give 20-20000hz(-3dB) for under $500....last I checked a few years back, nearly impossible.
Drivers are rated by their sensitivity which is the Sound Pressure Levels in dB they can output with a 1watt input. The more sensitive a driver the louder it can play while drawing the same current.
Typically a driver with wider frequency response will require a greater current draw and hence will have a lower sensitivity.
