What do you think happens when you feed a 490Hz signal into a speaker? For 50% duty cycle, it will respond as if it had a DC bias of 2.5V... with a 2.5Vpeak 490Hz square wave. Kind of defeats the purpose of smoothly pulling it back and letting it go when the speaker is flying back and forth between zero and full excursion (by full I mean the max it will move at 5V).

How will you tell when the "sound distorts"? What does a square wave sound like when it distorts?

You will definetely hear the speaker hitting it limits

Yes, you'll hear it hit the limits as it roars at you at 490Hz. Hardly what you need to create a vortex ring or "kick" of air.
