I am trying to understand what you don't understand.
Let me just lay out a few basics on sound reproduction.
Assume for now, that the sound is perfect in the digital domain (it's not, but that simplifies the discussion.)
Now, the digits are converted into a continuously changing voltage. The voltage represents changes in air pressure (all sound is changes in air pressure.)
When this changing voltage is applied to a speaker cone, it's causes the speaker cone to vibrate. The speaker cone does not generally vibrate at a nice simple frequency as real sound is made up of many waves at various frequencies and amplitudes.
The speaker cone is imperfect. So it's vibration will not perfectly reproduce the original sound (which was stored digitially.) In other words, it won't create the exact same changes in sound pressure as the original (which in many cases consists of artificial sound such as synthesizers and electric guitars, and was never recorded via a microphone to begin with!)
Smaller speakers are better suited for higher freq vibrations. This is why tweeters are smaller.
Larger speakers are better suited for lower freq vibrations.
All speakers are a compromise of cost, efficiency, power handling, size, bass extension (how low they can go,) and accuracy to name the obvious factors.
You can build a really crappy speaker really cheap but it's accuracy will be poor. You can build a smaller speaker, but physics dictates it won't play as low of bass, but it's cheaper to make....etc.
