Can someone check this for me? MT 15 box

[sj_grendel 10+ year member]

The MT 15 is on the way and I'm trying to get a design together before it gets here. I am using bassbox pro , which might be off bc it doesn't calculate for L shaped ports , nor does it figure in for slot ports along the back wall of the box.

I used this site for info on how to do the math for bending the port.

If this method is correct , and using bassbox's math . I come up w/ this.

Can someone please check this for me? Is the tuning correct for 35hz?

Will this box work well w/ my MT 15? Is that enough bracing? Is 82 sq inches of port enough?
