Box design - Two 12" subs

[bigone5500]

I am planning on installing two Soundstream X5.12 subs. I am going to use a ported box but am unsure if it would be best to separate the two subs and have two ports or is it ok to have them in one chamber with one port?

id just do one like this.  as long as you get the right volumes etc, should be fine
