I just recently built this box. Looks great and fits my speakers well! Can’t wait to finish this system!

Awesome schematics

My box turned out amazing. You can definitely tell the difference between a mass produced box and this. I paired the box up with 2 12" Kicker comp VX 4ohm subs that are rated pretty closely for the specs of this enclosure. If you're going to attempt to make this box, make sure you have all the right tools for the 11° angle cuts nessecary to building this. Will be buying a dual 15 enclosure next!
