Help with box dimensions?

[620hpcrx 10+ year member]

I am making a ported box for 2 12 inch subs. I everything calculated and most the measures but i dont have the box dimensions. It is a 2 chamber ported box with 1.6cu ft in each. The ports are round and are 3"x8" with 1 in each chamber. Can someone figure out the dimensions on the outside ( Im using 3/4" mdf). Also, are those ports ok. WinISD says it will be tuned to 29hz.

Ok I have diminsions but I need someone to look at them and tell me if they are ok. 35lx15wx14h. Would it be ok to put the ports on top not on the baffle???

You're tuned to 35 hz as it is.

Add an extra inch to the height or depth to account for the volume you use with the woofer and ports.

3x11" ports will tune to 29hz.

Ports on the baffle facing the back if you can.

What subs are you using?
