Hi folks.

I'm just concluding the final phase for a simple vented box.

As I constructed the cabinet entirely based on the speakers properties, now should I leave the inside of the cabinet free or...
may I stuff there a small carpet in "U" shape, going around the vertical part of the vent?
Is it necessary? Or do I just leave like it is?

Hi

Glass fiber should not be used in vented speaker designs because there is always the danger that some fibers will be blown out of the port. Glass fibers are not as dangerous as asbestos, but getting them into your lung should better be avoided.
My bass reflex speakers are damped with something like this foam - only a bit thicker:

There are several other materials in common use

As your cabinet is only made of 9mm boards, maybe bitumen pads to dampen resonances would be good too

Only don't obscure the inlet of the port with damping material
