Hey guys i came up with a design i just want to know if i did this right let me know its 4.4 cubes not counting port area and its 40 hz can somebody double check this and confirm what i did was right thanks

Your gross volume number is right.

However, a 7" wide x 13.5" tall x 16" long port does not give you 4.4 cubes @ 40 hz. Factoring in sub displacement of .4 cubes (guesstimate), you have 4.53 cubes net and my winisd says it's tuned to about 48 hz. If you want a 4.4 cube box and tuning of 40 hz, lengthen the port to 28" and increase the gross box size from 5.9 to 6.3 cubes.

If he doesn't want to design you a box the company in my sig can

i re did this this looks right to me what do you guys think

That is an awfully high tuning, imo. If you still wanted a high tuning. A couple changes I would make are, the port is almost ending in the corner I would increase the port wall a quarter inch and throw a 45* in the corner. That would put your box at 4.18ft^3 @ ~38hz, im guessing sub displacement at .16ft^3 per sub also.

4cubes net @ 38Hz with 64^2 of port area would work well. If you can go bigger that would be even better since you don't have a ton of power on the subs. 4.25-4.5^3 net is what I'd shoot for...
