Hi all,

I have a NAD AVR with built-in Dirac Live, but only one subwoofer channel. I have two identical subwoofers, but rather than simply y-cabling them together, I'm thinking about adding a DDRC-24 to split the single output to two individually EQ'd outputs.

I've read through the guides that explain how to do this with the 2x4 and REW, and though I'm comfortable using REW, I've been impressed with Dirac, and would like to use it to get my subs coordinated. Intuitively, it seems like the best process would be:

  1. Use the DDRC-24's Dirac Live on the two subs, and apply the desired target curve.
  2. Once the two subs are coordinated downstream of the DDRC-24, attach the apparatus to the subwoofer output of the NAD AVR.
  3. Run the AVR's Dirac calibration on the full speaker suite, including the subwoofer collective (as one), and apply the same target curve.

Does that pass the sanity check? If so, two followups:

  1. Does Dirac account for phase and time alignment between the speakers and subs, such that the "Sub Distance Tweak" isn't necessary?
  2. Any word on whether the Dirac Bass Management Module is coming to the DDRC-24?
