Im super noob to box building and have had the sub in front of me for a week now with no design I waited for 2 months for my sub to arrive thinking I would of had it built and done but no sir..... Ive spent the last 2 months trying to learn how to use box calculators with no progress LOL! I would pay for a killer design!
