Default New project.

I'm about to starts a new project, a WWMTMWW..
the woofers im going to use are 8" AR woofers, they have a EBP of 66.1, wich is a the limit between vented and sealed , still a lil better for vented, but on this project I want to do them sealed.
Im going to do the speaker using a half sonotube, one thing im worried about is the structural integrity of the sonotube, when the box is slealed, the pression is greater than in vented speakers...I was wondering how would the sonotube perform. Of course i'll brace it generously.

anyone has ever done something similar?

and can I do one side (as its a wwmtmww, and the each ww will be separated from the other ww's), vented, the other side sealed?

when i make some calcs, at - 3 dB i get 54 hz with sealed config
and at - 3dB i get 28 hz, the problem is that at sealed config i'd need like.. 10 cuft... wich is a bit too bit

when sealed it needs half that.
