How come in REW my sub graphs looked great? I was using REW in conjuction with the iNuke DSP and tweaked until they were pretty much flat. This is how they ended up before running Dirac... I can turn up the gain more on my iNuke if that is what you are referring to. It is at least 3/4 or maybe even 13/16 of the way up currently. That would mean running Dirac again too then right?  |

Ok, I have spent another day messing with this. I made sure AGC and the mic was at 100% in Windows, also used the cal file for the Emo mic. First, I did a factory reset, then I adjusted my subs using the iNuke DSP only. In Dirac I set it up as Sub = None. That way it will not try to correct anything and I will just add them back after running Dirac. Here is how I got my subs using REW and the iNuke DSP...  Here are my Dirac results, looks like nothing is being adjusted too much, I sure hope this helps with my volume / head room issue. Fronts...  Center...  Rears...  |

Do let us know.
If I'm reading the graphs right it looks like Dirac is adding a 10db boost to the fronts at just over 20Hz. That might kill some headroom. I'd be inclined to moved the curtain up to 30Hz so that Dirac doesn't need to touch the trough below that.

I have don't have Dirac full so I cannot move curtains  At 20khz it looks even to me. I see about 7-8db of boost around 14-15khz though. Well, I played some music videos through my PS4 and tried using an aux in and I had the XMC all the way up (+12!) This is so frustrating. I saved and spent so much on this thing and my cheap UMC had way more impact! Even with movies you can hear things limited, there is no impact! The only thing I can do is use a preset but then there is no RC...I don't know what to do anymore. |

The only thing I can do is use a preset but then there is no RC...I don't know what to do anymore. At this point I would do this: 1) Call Emotiva. I know you have to call during work hours and would need to be with your setup, but please schedule time. We all have to sacrifice. 2) if your call does not produce anything new, I would pony up for Dirac Full. I realize that it's not ideal for you due to cost, but it is much more powerful. |

Are your subs still set to None?

I just played tones 5-200hz and adjusted the filters frequency, level and width to get it as flat as I could. |

I'm fairly sure that the storage area for the Dirac filters is separate from the area for the rest of the XMC1 config (the one cleared by the reset). You might end up with remnants from your previous cal by enabling channels that weren't part of the most recent Dirac cal.

What looks even to you is the green trace which is the "After" trace. The difference between the blue "Before" and the green "After" is 10dB. Disregard the orange target line. |

I see the blue down around 14-15khz. My speakers start rising back up around 20khz. The boost I am reading (from blue to green) is about 7db around 15khz. |

I already said that I don't think that is necessarily part of the reset. I know what the name implies.
Assuming OPs crossovers are 80Hz, all channels are down 15dB at 40Hz. Any filters below that point shouldn't be affecting anything.

When using the software it only had 5 speakers FL, C, FR, SL, SR. It downloaded to the XMC once done, why wouldn't it clear out the old filters? |

Even so, Dirac may be setting final levels based on what may be asked of the mains. |

I don't know of a way to clear out old filters. Basically, you're calibrating the system in a manner that is not valid/defined. Thus, you can't really trust the results.
I haven't run Dirac in a while and can't remember...can you exclude a channel from correction? I wouldn't be surprised if it requires the full version as I think I had to move the curtains for my bass shakers.

Yes, the subs were exluded from correction because I set them to none before running Dirac...downloaded the new filters then turned subs back to dual mono.

I don't think Dirac would treat the fronts any differently with or without subs. Each channel is measured on it's own and as full range. Final levels are set and do not change afterward if you turn the sub on. Dirac knows nothing about crossovers as they don't even exist in it's world. So I'm seeing Dirac compensating by putting in a 10dB increase at 20hZ and probably adjusting it's final levels accordingly.

NOW HEAR THIS
There is NO WAY to clear existing Dirac filters once they have been calculated and downloaded.
Once Dirac Live has been run and filters exist, the most current filters WILL be applied when you use the Dirac Preset.
The ONLY way to change the filter for a given channel is to create and download a new one.
There is no option to wipe, delete, or clear the existing filters.
Neither doing a factory reset nor reloading the firmware will clear the Dirac Live filters.
If you disable your subs, then run Dirac, then re-enable the subs, the previous Dirac Live correction filters WILL be applied to them.

I haven't been part of this thread but have been following along, thanks @keithl for this clarification! I find it most helpful.  |

Ugh, so after all that I am still applying my old sub filters using Dirac?! So now what are my options?
What if I just use 1 sub when running Dirac? I believe Tony had threads recommending this and not using both subs if they are in oposite spots of the room anyway. Use the flatter of the two in hopes of little correction?
