Somewhere on the forum in the old threads for the XMC-1 is a discussion about setting up Dirac and subs. The consensus seemed to be that it was best to let Dirac tune the subs using a Y cable and connecting the 2 subs together as one. After Dirac was done then use a minidsp to correct the time difference between the 2 subs and make any minor adjustments using REW. This worked well for me when I had my subs at opposite ends of the room. If at all possible I would suggest some panels for the wall made from Safe&Sound and also add some diffraction such as book cases . emotivalounge.proboards.com/thread/40671/alternative-dirac-technique |

I think you would want to perform the MiniDSP portion first. Changing the alignment after invalidates the Dirac filters.

My subs look pretty good for 1/24 right? I have not reran Dirac, I think I'll keep it were it is for my Sat party, it does sound much better than before. I wanted to turn my subs up louder so Dirac doesn't boost as much but then it clips in Dirac so that is no good. I found the best is to try and flatten them as much as possible before running Dirac so it has less to correct. I'll keep the XMC-1 trim level at 0 and just use my gain knobs on the iNuke if I want it louder, that should help with headroom too.
On a cold snowy day off I will plan on really tuning the iNuke and running Dirac again. I found that wider measurements (22" or so with 10" above or below the MLP test) made it sound much better.
I am having issues understanding the width setting in the iNuke though. Sometimes a high number (6) will make things look good and other times can change the whole line! Usually I am around 2-3 for the width setting. Can anyone explain that so I can guess more intelligently?

Here's how I got my subs after some fine tuning and using 1/24 smoothing...  Subs look fine. But have you tried running a trace with both running simultaneously to see if there is any weird interactions? |

(Broken record) The full version of Dirac lets you adjust the volume level on a per channel basis.
Are you talking about Q or bandwidth (not exactly the same, but not going into it)? They affect how far out the gain applies from the center frequency. Higher Q is more narrow width and affects less frequencies. It's not uncommon for small changes in EQ to affect the overall response in unexpected ways.

Here is both subs playing the sweep together...  |

Here is both subs playing the sweep together... If you overlay that with the individual curves then ideally the combined curve should be at a higher level across the entire range. If it dips below the individual curves at some points then there could be a phase difference at those points. From what I can tell, yours looks okay. |

Quality = Q
