Built in Stage Sub Questions

[kano32]

I a recent post regarding placing driving in a stage. I have a 13'x15' dedicated HT room waiting to be drywalled. I was thinking of building a small stage to house 4 Rl-p15's similar to the picture below (those in the picture are 18"s and it's huge). I am hoping to keep the stage around 20"H x 20"D x 13"W. Anyone know if that will be big enough for 4 15's and if so do I need to vent it or is it big enough to be considered an IB. I could also open up the floor into the crawl space to make more volume inside the box. Any help would be appreciated.

Oops, forgot to attach image of sub that I want to copy.

20" x 20" x 13"... that's only around 3 cu ft!

Perhaps you meant to say 20" x 20" x 13', which would equate closer to 36 cu ft.
If that is the case, ~ 9 cu ft per RL-p15 would be pretty **** stellar!

Yes I meant 20" x 20" x 13' (the width of the room). I could tweak the first two numbers a little larger if you think that would help.
