Please help me calculate my port size

[therealkbone]

Hi guys! 
 

So in winisd pro there isn’t an option to load any SA drivers and so I’m asking for help here, any and all is appreciated! 
 

So I’ve got a single SA10v.2 D2 and a JLrd600 

 

i know I’ll be running it kind of low but for now that’s what I’m working with. 
 

to compensate for wattage I’ve built my box and added cubes. At the dimensions my box is I’m just above 3 cubes. Box dimensions are 27.5 inches in length

15.5 inches wide

12.25 inches in height

 

Sundown recommends tuning at 35hz 

i listen to rap, edm, and metal. So I’m open to suggestions if anyone thinks i should tune differently. 
 

Based on all the info I’ve given can someone please help me calculate how big my port should be and at what hz to tune?

The enclosure suggestion that sundown offers is actually larger than their suggested specs by a quarter of a cube, if you oversize the box too much it will perform poorly on the fast "punchy" bass that musics like metal need to sound good. So Sundown's box would be my suggestion for you.
