Mdf is inherently pourous
My big cnc machine has a vacuum bed that will happily suck down an 8x4 sheet through another 8x4 sheet.
Air tightness over a musical transient is not the same as a box that will over a couple of days equalise atmospheric pressure.
So please no more talk of putting pin pricks in roll surrounds or some dickhead will actually do it!
What about between the two drivers? There is no MDF there it's plastic and doped cone.
