This morning I did a DIRAC re-run. I slightly changed the measurement positions (a bit closer to the main spot) and I reduced the MIC sensitivity and hence increased the test tone output a bit more compared to previous measurements. Here are the results (only showing the front speakers). ORIGINAL EMOTIVA CAL FILE:  CROSS SPECTRUM CAL FILE:  I can conclude that the result of the CS CAL file resembles more to original output level of the speakers, especially in the higher frequencies. First listening results is that I liked the sound of DIRAC with CS CAL file a bit more. There is some more deep bass and the higher frequencies are bit less prominent. For the time being I'll keep the calibration with the CS CAL file. Just I bit strange is the small "dip" around 600 Hz in the spectrum before correction. You can see that the CS CAL file data has a slight change in sensitivity in that area. Strange. Anxiously waiting for the DIRAC Full version. Probably I'll sent my EMM-1 mic to Cross Spectrum for calibration (if shipping costs to and from USA - NL are not to crazy.). Again very big thanks to everybody who have contributed to make this happen. The full version should allow you to use any calibrated mic. With shipping overseas. It might be cheaper to pick up one of their umik microphones. Tony |

So, if I am understanding this correctly and based on all the hard work by Tony and Socketman, sorry I'm not aware of your real name, it seems that the Emotiva provided CAL file is the culprit. An updated Emotiva CAL file could possibly address this issue?

The real fix is the Dirac Full Version upgrade. If that were available I don't think any of us would be posting about the EMM microphone or calibration.
Get yourself a calibrated UMIK-1 from CSL and be done.
Just waiting on Emotiva & Dirac to make it available.

No sure, I was always planning on upgrading, but for those that don't wish to spend the extra $99, an updated CAL file from Emotiva appears to be what is required?

An updated Emotiva CAL file could possibly address this issue? Kinda, Based on Lonnie's statement, the calibration file is not accurate for off axis measurements. But the emm mic + the not accurate calibration + the house curve (making further corrections) = a result that emotiva found to be good. But given this, the house curve and the dirac graphs are visually misleading. I will try post more later when I get to a computer. Tony |

Thanks Tony... I'm just trying to wrap my arms around this.

Tony Emotiva not only finds the result good, but other's do to, including myself. Best sound I've ever heard in my system. Having said that, if it can be improved for everyone, why not? |

I'm thinking of ordering an umik microphone which one should I order.
Thanks

So, because the microphone calibration file was wonky, EMO fudged the house curve to get an acceptable sound?
Doesn't that mean that if you use a corrected calibration file for the EMO mike, or your own mike and calibration file, you're still stuck with a fudged house curve? So you'll need the "full" version of Dirac so you can also correct the house curve. Now that we know why, I wish EMO would just suck-it-up and issue the corrected files, so we didn't have to do all this compromising.
Dirac has all the test gear to get the house curve and mike calibration right; why don't they?
Sincerely /b

Add me to the camp that says thanks to CS, Tony and Socketman! I just got done rerunning Dirac LE with the CS file and my initial impressions are the sound is way more to my liking. I have bass again and my highs are tamed. My graphs look much better, no huge dip after 10k. And my bass is back. Not quite as much as I like, but enough that I think I'm happy with what I have knowing I can tweak it once we get the full Dirac version. I just hope this full Dirac version is truly the real Dirac and not an Emotiva version of Dirac that takes some of the functionality of the full Dirac version away. 1. Mains Emo Cal FIle 2.

It would seem that if I read Lonnies reply correctly the EMM-1 is specific to their version of Dirac. If that is the case anyone upgrading will then have to purchase a different calibrated microphone that will work with the full version of Dirac. So another 100 for Dirac full and another 100 for a calibrated Mic plus shipping, hmmm .

He said they will provide a generic calibration file for the EMM-1 that can be used with the full version of Dirac for the XMC. No matter what I would buy a calibrated UMIK-1 from CSL or send your EMM-1 off to them for a calibration. |

No matter what I would buy a calibrated UMIK-1 from CSL or send your EMM-1 off to them for a calibration. If the mics are as consistent as Keith said they are then the cal file I had done at Cross Spectrum will work fine. You will still only need the narrow band 90deg file for use with dirac full. I actually bought a second mic and sent it to Cross Spectrum to speed things up. The new mic will be here in a couple of weeks and I will compare the 2 when it arrives. I see no reason I could not compare 2 identical mics to each other using REW. |

Tony,
Using your file which boosts the readings by as much as 10db in the hi frequencies, one would assume then, that Dirac will not try to boost the hi frequencies by that much, will we see greater headroom in our volume, quite a few people have complained about lack of headroom.
