Need insight on my 2.0 compact desktop speaker with plans for a subwoofer build

Hello , I am on my journey to build my first set of speakers .
I need a compact speaker set that occupies minimal footprint on my desk.
I would like to add a sub woofer to my setup , but in order to reduce complexity of my first build , I have decided to stage 2 .
And I would like to 3d print the enclosure (either with high infill or plaster of paris mould)
So with this goal I decided to go with full range dayton RS100 4" drivers , as I wasn't able to find woofers availability in my country which I can fit in a sub 6 litre enclosure .
With winisd , the rs100 seems to behave well in a 4 litre enclosure with a vent of diameter 3 cm and length 11 cm . This dimensions seem feasable for my needs .
Will use a baffle compensation circuit and a notch filter to smoothen the FR graph for each speaker .
Will design the crossover with sub when I will add it in few months .
Hence I have started 3d modelling this enclosure, With circular vent on the top , and internal and external fillets to avoid front baffle diffraction.
Planning to fill the enclosure with glass wool.
So I have following questions :
  1. If there are ny glaring issues I might be missing with my plan , it would be helpful to know .
  2. Will following wiring work when I upgrade the setup with a subwoofer? https://ibb.co/5ns2tyv
  3. Will the depth of enclosure need to be a specific value for the speakers to behave well ?
  4. Does the sound dampening material inside reduce the volume of enclosure ?
Thanks!
