3 Layers in total make up the front baffles...
The inner most edge has a 1/2" radius to help air flow at the back of the woofer
Offering up the baffles to make sure they fit
The weird cut outs I showed you before, are the braces for the inside of the box as well as the magnets as the subs weigh around 40-50kgs EACH! Not only are the 18" in diameter....they are nearly 16" DEEP!!!! Imagine the leverage weight on that!
And test fitted with the port
The back panel was then glued up
And joint the rest of the box!
Time to strengthen the top of the box!...An extra 2" of MDF going in
