Take the speaker grill off, and play a record with lots of bass, best of all an LP with a bit of a warp, and watch the antics of the woofer cone. I think you will agree that it is a wonder that the poor woofer reproduces midrange at all.
Also, some folk think that the slightest movement of the speaker "blurs" the midrange, and they go to great expense to immobilize their speakers. Well, with the midrange emminating from a cone that moves back and forth 3/4 inch or more, what does that do to the midrange?
I think that the main reason to have a subwoofer is to get that LF which requires long cone excursions, out of the woofer. Oh, and it helps the HF power amp too.
