making 45 degree angles
exactly how do you make 45 degree angles for the corners. i was guessing you just make a triangular prism out of wood with both angles 45 degrees but i **** at geometry so i was wondering how. I'm trying to squeeze 4 more db's out of my setup so i'm hoping doing this, get my trunk closer to a 100% if not a 100% and some more deadening (still need to do doors, roof, rear firewall and maybe the floor) I know that having your enclosure solidly mounted to the floor helps output and response in home audio (or at least according to the parts express catolog) but is that true for home.
