Hey guys I'm designing a box for one of my buddies who has a alpine type e 12, Alpine says optimum vented enclosure is 1.25 tuned to 34 hz I believe I got it pretty close. Would you guys be able to let me know if I made and large errors?

Thank you all for your timeAlpine Type E 12 (check my work?)-alpine-type-e-12-1.jpgAlpine Type E 12 (check my work?)-alpine-type-e-12-3.jpgAlpine Type E 12 (check my work?)-alpine-type-e-12-2.jpg
