So let me ask this, why different sizes in the first place then? Is it really just for frequency response?
Yes, it's mainly about frequency response. Plus low frequencies need POWER and you need to move lots of air.

Why do they make monitors with small woofers? Or, why do people buy small monitors? ….Mostly cost & space.

Big studios with big budgets and plenty of space usually have big monitors as well as small "nearfield" monitors. Take a look at this "random" picture I just found... Two pair of smallish monitors on the console and 4 big woofers (or subs?) further back.

If you could make a 5-inch woofer that's flat down to 20Hz it couldn't reproduce the sound of a bass guitar or kick drum because it can't put-out enough power. Your hearing is less-sensitive at low frequencies so you might not hear anything at 20Hz, and that "flat" speaker would be less sensitive (more quiet) across the full frequency range.

That's just physics.. A kitten can't roar like a lion. Whales and elephants can make subsonic sounds.

But again these are just generalizations... A bigger woofer doesn't always put-out more bass or better bass... There are lots of factors that go into speaker design.

Is the frequency crossover better or worse at different sizes?
No. It might affect where the speaker designer puts the crossover and if you go with a BIG woofer, you're probably going to need a 3-way design (2 crossover frequencies) because the larger woofer might not do a good job with mid frequencies. It does get "more difficult" at/near the crossover where the sounds are coming from both speakers and the soundwaves have to mix in the air, so a 3-way design is "more difficult" to get right.

Why would someone want Twin 6.5 with Tweeter instead of a single 6.5 and tweeter?
100 small woofers could put-out a ship-load of bass... But 100 kittens can't roar like a lion...
