Digitality doesn't define frequencies, besides they can (and will) be
mixed (you know that GSM-noise that comes out of your speakers if you'll
keep phone too close to preamp? It's ~200Hz, while the phone's interval
to discuss with base station is 4,7ms). Digitality defines having
limited amount of values, theoretically making the sound being like
morse-coding. OTOH, if you calculate the pulses to match the speaker
correctly, you'll end up with normal sound (the speakers have inductance
and capacitans) by using the speaker itself as D/A-converter driven by
eg. PWM.

Ah, and don't worry about amplitude. Amplifiers have been invented.
