Trying To Prove A Point

The woofer cone is much smaller than the wavelength being produced (100 Hz is 11 feet ) so the coupling efficiency to the air is very poor. Bass drivers overcome this problem by having larger excursions. You can't see a tweeter move (max excursion of 1mm or 2mm) but a woofer can easily be seen to move for loud low frequency notes (max excursion of 10mm or 20mm typical). So the woofer moves a larger cross section a greater distance or simply put, a lot more air, this takes more power.

When Pix was insisting that it took more power to drive a tweeter than a woofer, I listed several models of powered speakers along with their specs, Without exception, every speaker featured a higher-wattage amp for the woofer and a lower-wattage one for the tweeter. Since Pix never responded, I'm assuming that he came to the conclusion that he (just possibly) might be incorrect.

If you google "bi-amped powered speakers" you'll see what I mean.
