Speakers better without subwoofers? Crossover and synchronization issues? What do you do

I bought main speakers 25 years ago, spkrs seemed to have much larger bass drivers back then,  and nowadays subwoofers are a staple in audio systems, while bass drivers have tended to get smaller in diameter on main speakers, why is this?

Wouldnt it  be better to have a larger bass driver in a main speaker   rather than having timing issues with a pair of subwoofers? Also seems crossover designs might allow for a better sounding experience if they are part of a main speaker. I do have a Single subwoofer that I use to vibrate the room which works pretty well watching movies, simulating tank movement is really cool although don't use it in two channel listening at this point since it's older.
