Hi Brad,
I know i would need min 4, but the budged does not allow that for now. I also know a few here use them 2 + 2 and did OK. I am thankful for every input on this.
From my experience, i did fine with filters set to 80Hz. I have 6x15" to cover up from 70-80Hz plus the 3x15" on the fullrange boxes. I am more worried about the mid-high...
Thank you, Bogdan

Hey Bogdan,
The filter being referred to here is a High Pass, not a low pass. You need to protect the 12's from ultra low frequencies, so you should set a high pass of at least 12dB/octave.
You have 6 dual 15" boxes, and 4 lab subs to work with. I am with Tako, place all 4 lab subs in front of the center of the stage, and the dual 15's below the tops stage left and right.
If all 4 LABS are together in a line, they will couple at the lowest frequencies, giving you some additional extension.
I would have the dual 15's run down to around 45hz to give you some extra low end.
As for your tops, you can increase the throw by stacking them vertically. So rather than 4 wide, I would do 2x2 like this:
W W
m m
horn horn
horn horn
m m
W W
And then splay the tops along the coverage pattern of the horn.
So, in summary
Top Top Top Top
Top Top Top Top
Sub Sub sub Sub Sub Sub
---------------------------------------------------------
LAB LAB LAB LAB
Guessed ranges:
Labs: 35-80hz
Subs: 45-100hz
It's really hard for me to say without me sitting in front of the PA with my smaart rig out. I think you'll be OK as long as you are doing the mixing, and keep the volumes around 95dBA or so.
