phase cohesion is of course important. you want to make sure that the sound from the subs arrives at your ears at the same time as the rest of the music. You will need to adjust the phase to within less than a degree if you want perfect time coherence.
You dont need 5 subs in a small room. One is enough. More subs will take up more space and use more energy. Most of the bass will end up cancelling the other subs.
Smaller subs are faster as they have less mass. So they can accelerate more quickly.
Cheaper subs are made of mdf but if you want the best, concrete cabinets are a must.
The best subs will start and stop instantly. The worst ones will ring like a bell long after the signal stops.
perfect subs will give you clean bass everywhere not just in the sweet spot.
