Mmmmh, regarding that sub: the walls ( 1/4 of an inch?! really ?! ) are very thin. I see, lecturing that thread, that you like dipole, so it's easily explained.
But being the major point of making a box for 'sequestering', suppressing, isolate the two emissions, no matter if the box is closed, BR, TL, the function of a baffle in an enclosure is to isolate (again) and 1/4 " of plywood isn't going to do it.

I've used the website before but I had never seen all these sheets. Excellent work, I am grateful for your passionate efforts! I will be using these sheets for sure
@picowallspeaker Maybe you contributions (the comment) would fit better in place on the dedicated page of the sub build! My 2 cents: ¼" plywood can be excellent since it enhanced some desired resonance but also facilitates unwanted resonance, so if used properly it's amazing but it is a finnicky thing
Depends on material/construction, panel aspect ratio and what, if any, bracing used, so this is anything but an absolute.
