ported box for adire shivas

[blackrob99]

hey guys,

im getting a custom ported box constructed for my adire audio shivas (12") and was wondering what dimensions it should be (dimensions of box, amount of air space, etc.) has anyone ever built a box for the shivas or know what the dimensions of a ported box should be?

all help appreciated

2-3 cu ft....tuned to around 28-33hz should still sound good yet maintain sq
