Ported subwoofer stuffing

[audio amateur]

So i've been browsing around the internet about what the general consensus is on this, but i don't seem to find it. Right now i've applied some wadding (about an inch thickness) on parts of the inside walls. I'm wondering whether or nor i should put more. I suppose i can try to experiment without screwing back the driver in place.

What are your experiences? Some people say there shouldn't be any at all in ported subs. What's your say?












Just a few pics so you can have a look at the sub
