    I'm currently stumped on how to go about BFD'ing 2 subs in my setup.

    I'm using the DSP1124P so I can in fact do this without problem but can somebody offer me a process by which I do this.

    Is it simply a case of BFD'ing each one seperately or do I do both together?

    I use a Real Time Analyser with the Behringer ECM8000 mic rather than the SPL meter and Excel spreadsheet method if that makes any difference.

    Hi ShinObiWAN, nice stuff you have there, and a tough assignment.. ;)

    I would try to put the subs first in the recommended places you read about on the net, "middle left wall & middle right wall" among others. I hope that one of the subs has a fully (0-180 degrees) variable phase dial, as this will help a lot.

    For more read these topics/links:

    I skipped through the links a bit, and I see people there stack their subs, I don't know if that's an option for you.

    Yep they have the variable phase control so hopefully that will make it little more simple.

    To be honest I knew it would be pain but I believe that 2 subs are worth the effort if done correctly.

    ShinObiWAN - where are your subs in your room? Are they both at the front, left and right, one front, one rear?

    Hi Chris,

    They are positioned about 2 feet in front of the mains against the left and right walls.

    ok, i'd be inclined to do both at the same time then. you might want to consider using a splitter and use one BFD channel just for the setup - then you can copy the settings from channel 1 to channel 2 for normal operation, just might make setup easier if you only have to alter one channel for both subs.
