Physics of downward firing woofers

Ok ... this question will show my complete lack of knowledge about physics ... but here goes anyway:

Every now and then I come across a speaker with a downward firing woofer. I wonder: why don't the sound waves bounce off the floor back towards the speaker, rattling the bejeezez out of it and / or messing up the woofer itself?

The main advantage of a downward firing sub is to avoid forward driver modulation that would compete for your attention by adding confusion to the highly perceptive mid and hi frequencies.
try reversing your subs and experiment with 180 switches and this is for many folks an improvement in focus.
Downward subs, when used with neutral speakers, will be complementary
 in balance.
