Here is a non-optimized bass reflex that I would not build. It is just an example to show what happens when you cover up the front of the driver. 120 liter box and a 150 cm2 port 60 cm long.

Here is the same bass reflex box with a 100 liter closed box covering the front of the driver (black curve).
