the bracing is (2) 1" MDF (vented) and glued together.
I misjudged my bracing a little bit (due to a late design change) but it's ok, i worked it out.
Of course this thing will have SMD Neo Magnet quick release terminal cups.
This thing will have a 1" Clear Acrylic window. For that, it has to be framed in. I notched the back side 1/8" so the mounting frame had a spot to sit. (not shown). It made it a lot easier to install it as i didn't have to measure/center anything. It just dropped right in it's little pocket. All i have to do now is get the Acrylic and mount it (once the box is done of course).
Nothing is glued at all! except the L shaped port. And it isn't even glued in place yet. I also glued the two braces together but again, they aren't actually mounted in the box yet. This thing is like a house of cards ready to fall any second....although the notches made it a lot stronger than normal just sitting on the table. I plan on gluing it tomorrow if i get time.
and no, the panels are not crooked or off. They are perfect. I think it shifted while we were putting the sub in. But it is clean, i will line it all up tomorrow before i glue it of course.
