Hi All
I need advice to get my old sub back in game.
Some 15 years ago I built HT DIY subwoofer project following some advises from community.
Driver used is visaton tiw 200 XS
TIW 200 XS - 8 Ohm | Visaton
Box is BR app. 54liter(brutto) box made from 25mm MDF with double internal bracing.
At the beginning I was happy with sub for HT but my neighbors not so.
As I have grown older I found out that I like this sub more when I close bass reflex port with some foam.
Few years ago plate amp on this sub died and I stooped using it.
Now that I got new nice L/R/C speakers, KEF R3, R2c I would like to put it back in game.
This time I would like to have closed enclosure as I think it will be more controlled and I need only just a little help for my front speakers.
Can you advice if I need to make enclosure smaller or just fill it with some dampening material as I reed on drivers web page for closed enclosure advice to be 30 l/closed--46 Hz/0,68enclosure but mine is 50l at the moment.
I plan to simply close BR tube with foam.
Sorry for my English
Thanks

Just play a little with WinISD. It is free and not that hard.
Here you see some SPL plots with your Visaton.
The blue lines are sealed; 30L and 50L. The greens are vented. 30L,50L and 70L.
You see that a port could extend the lows pretty well, except when you make the enclosure too small. At 30L the vented is almost equal to the closed case.
