You would still have to double the amount of boards and put a pair in series... IE 4 boards, two for left, two for right, one left/right would be graphic, and one left/right would be Parametric.i still dont think it would work with my intended set-up (4 way full active) coz the two boards would configure like this:
1 for the left channel
1 for the right channel
so if thats the case 1 board would have the graphic eq plug in, and the other board would have the parametric plug in.
correct me if im wrong though coz im not that technical.
This would come in at ~1/2 the price of an MS-8.
