I'm currently building speaker pods for my front stage.
I have two Resonate Engineering 8" sub woofers for mid bass and
two 4" pioneer two way coaxials for the mid range?
Here are picks of the progress, well some of it.

I was thinking about making a fiberglass enclosure for 4 infinity perfect 10" subwoofers. But not sure anymore. Kinda low on dough right now

you can also see a pic of the sub amp and xovers for the 8".
