I know that the larger the sealed box is, the lower the sub'll hit and less power it'll handle, why is this though? Why is this not the case for ported boxes? Thanks all

Think of a sealed box as a compressed spring. the smaller the box...the tighter the spring. basically, the reason sub in a smaller box can handle more power, is because the pressure inside the box has greater control over the suspension...meaning, the sub will overheat(thermally) before it bottoms out(mechanically). however...since the sub is so highly controlled in a smaller box...the sub has a more difficult time playing notes which require more excursion...eg. low notes.
In regards to ported boxes... the size of the box does effect the power handling and its ability to play lower in some regards. However, the port length and port area (tuning) have a much larger effect... thats all I got time for...sorry
