Behringer Ultra Drive Pro DEQ 2496 Help

hello,

i have 3 subs and tried to bring them in phase. And now iam done so far and will the rest create with the PEQ ´s. I Use the Auto EQ function from REW , but the results are not the same as REW show me . BW Oct 0,750 by REW is 1/7 on the behringer Display right ?

so when in REW 0,750 is - what i must control on the behringer ?

ah ok can you maybe help me ? i have 3 subs and where i must start ? Whats the best way to bring them together ? I use 2 Behringer DEQ 2496 ( one DEQ 2496 for Right Corner and mittle Corner ) and the other DEQ for the back Subwoofer (3 x XTZ 12.17 )

Here is a picture from my room
and this is the best result that i get so far.
is the setup right with the Behringers `? Or i shoud setup DEQ one with Front and Back and the other (middle Sub ) with the other ?

sorry but the thread link follows me only to avs forum , but to no only thread

and other question , what i shoud first do ? before i edit so : first delay with volume edit then the peq for the modes for the sum of all subs. Is the line right ? or i shoud do before all room modes eliminate for each sub

i have use multi sub optimizer but the endresult was not the same like how in the program. Can you may help me , how i start with 3 Subs ? I have bought me now the mini DSP HD 2x4 , the must came in few days but until there woud i place the back sub maybe in the corner .

The sub 3 (in the picture upstairs ) what is the best position for the 3. sub ? Middle of the wall like right now or in the corner like sub 1 ?

my MiniDSP 2x4 HD arrived yesterday. Any tipps for me ?
