Low voltages, low freqs suffers?

If you look at a woofer when it is operating, it has to have a longer throw to provide more perceived audio output than a midrange speaker.

In a typical PA system there might be 1000 watts to cover mid/highs and 5,000 to cover lows. Longer wavelength... takes much more power to move much larger volumes of air. It takes nothing comparatively to jiggle air pressure with a 1" wavelength vs 80 Hz coming it at ~13'.
