Ok I'm going to start cutting tomorrow, finally! I'm building the bottom which will house the driver and the dual 3" ports as a double baffle. I came up with 16" W x 24" deep x 24.75" tall (to account for the double .75" bottom baffle) to get the 4.75 ft^3 required. Here's what I came up with for my cut list:
Front and Back: 16" wide x 24.75" tall
Sides: 22.5" deep x 22.5" tall (I'm fully insetting both sides)
Top and Bottom: 16" wide x 22.5" deep plus 1 extra panel on the bottom so three total panels in this config
Base: 16" wide x 22.5" deep
I'm building the standard box with the sub and ports firing down with the plate amp on the back. I'll build 3" stands to set the main box up off the base. How do the cuts look? Once I get them done putting the actual box together goes pretty quick.
Thanks for all the help!
