Life can be funny. Today for the heck of it, I switched from my own house curves to the suggested default. The default is better  |

no need to redo dirac. I would go 40 for the front 3 and 60 for the rear 4. 150 for the sub. The front 3 could be set to large, but i like to leave amp headroom where i can. The rears are being over extended if you go lower than 60. Up to 10db gain is being applied. The sub xover only acts as a low pass filter and you do not want to lose info from the .1 channel. All xovers will be set on the xmc and not dirac. Tony |

Tank's for the answer I have put 40 and 60 on the XCM-1 but I don't see for the sub
Is it on the sub I suppose to put 150 I have a SVS PB-12

This is probably a dumb question but im going to ask anyways, and I'm ex IT person and been into audio and computers since the mid 80's. Should I load dirac on my nice mac with good hardwar and El Cap or on my pos asus with win 10? Will the cheap hardware in the asus alter the results at all?

Well now if you are an ex-IT person and have been into computers that long, then I would assume you would know which computer is most suited.  |

The official answer is that Dirac should produce exactly the same results (which are based on measurements and calculations); both computers should read the same values, do the same calculations, and produce the same answers. As long as the hardware is sufficient to run the Dirac software, the results should be the same. (Minimum is probably a dual-core machine with 4 gB of RAM.) However, the reality is that the Dirac software seems to run more reliably on Windows computers. For one thing, there is a known issue with the microphone not being visible to the Dirac software, which ONLY happens on some few machines running El Capitan. (We've had a half dozen or so reports of this, and, on at least one of them, it works fine on the same hardware with Yosemite, but not with El Capitan.) We've also had occasional reports of "odd results", and they occur more often on Apple computers. Therefore, given the choice, I would opt for the Windows PC. This is probably a dumb question but im going to ask anyways, and I'm ex IT person and been into audio and computers since the mid 80's.

It runs like a charm on my pos Asus using wireless AC and Windows 10. I just don't like the vastly superior Mac with all their vastly superior OS's that have trouble running Dirac. But then I'm not an IT guy, just a user. |

I had more trouble running it on Windows than on my Mac, and in fact I had no troubles at all on my Mac

Ok thanks guys I knew it probably didnt matter and my pos asus will be easier since it is a laptop, it is not my mac though. My mac rocks |

I ended up getting an improvement by adding 8" OC 703 to my sidewalls (purple plots below, previous plots were on page 6 of this thread).
The next improvement took me a few months to finally try, but may actually help some with bass problems and those who primarily use a PC or mac as their media source.
I ended up using Preset 1 and hand set level and timing (using REW and mic). For the sub, I set the crossover at 80 Hz and tried several distance settings to ensure I had the best possible time alignment resulting in better phase coherence for the low end, then repeated after changing the slope setting, did it over again so that I was sure I had the best balance of phase coherence and amplitude.
After that I downloaded Dirac's software for my PC (30 day trial). Here are some of the results of before and after (same sub crossover, mic location, room treatments, etc...). These results are very interesting (posted a comparison thread under processors, but I'm not getting any useful feedback so thought I'd post here and see what you thought).
Given that I've blown $400 just in raw materials before (OC 703 and fabric) multiple times to improve bass and midrange, I'm seriously thinking the improvement might be worth buying the $750 software for? Blue is OLD using XMC-1 for Dirac, Purple is NEW (using PC for Dirac and XMC-1 set to Preset 1).
Thanks for taking a look and for your complements. Means a lot coming from someone with your experience! Yeah, going with co-located/stacked drivers like I did was my last big "idea" that I thought would materialize into a real world difference and it did as the reduction in ringing shows. The only other thing I plan to try is adding some 8" thick corning 703 panels to build even more of a reflection free zone around the MLP. Right now about two feet of the side walls have only 4" thick foam (I bought this before I learned about acoustics); looks pretty though. I expect a slight improvement, but no where near the improvement of this last conquest. For $350 in raw materials, I figure I can always move them to the rear of the room if I don't see an improvement at the MLP. I would say my system as it stands sounds world class thanks to all the panels in there now. Probably better than 99% of the studios out there, but I'm not in the audio business to know for sure. First of all, awsome job on getting it to where it is. Super impressed. Looking at the impulse, its likely your floor creating that early spike. But on the waterfall, it doesnt seem to be materializing into much. I am afriad I dont have much to suggest, you have a well controlled room with a really good response. Again. Awsome job. Tony |

Hrm... didnt get a email for this thread update.. the results your are getting look fantastic. You came a long way since your first posts. If you plan to do the atmos upgrade, then no dice on the computer version. Going to pm you my email. We can chat there |

Tony, Guys, may I ask you a few DIRAC questions?
I just re
-ran DIRAC again, when I got new front speakers.
1. I remember way back when I first ran DIRAC FULL that there was a place in Windows where I needed to go in and turn off some limitation to the microphone, or something important like that.
I cannot find it now, the place to turn it off or the recommendation to do so.
2. When I set levels there was a check mark by the subwoofer level. I was thinking this meant that the subwoofer was over the limit?? But nothing I did, however much I turned it down, I could not get this check mark to go away. So I ran it with that checked, is this alright??? The sub level sounded very low.
3. ALSO, can anyone point me in the right direction to set a curtain I think it is called, to somehow only have DIRAC filter the lower frequencies, say 500 Hz and down? I think that might be all my system needs, just management of the bass interaction with the room.
Can any of you help me out?
Thanks and God Bless, Merry Christmas everyone,
Wayne

Auto gain control. Located in the microphone system settings. There should be a video in the xmc1 FAQ. emotivalounge.proboards.com/thread/40758/dirac-xmc-1-work-progress?page=1#post-7062722. If i remember correctly, the check qas just indicating that it registered as a sub. 3. Need dirac full to set the curtains. You would drag the left and right tabs to set the frequency range. Tony |

Thanks a LOT Tony, that is what I was looking for.
I have DIRAC full, do I just pull the curtains AFTER I run the sweeps and BEFORE I create filters?
Will try everything again,
thanks, God bless,
Wayne

Wayne - try using the default curves that Dirac calculates for you. You may find that they work very well (they did for me)

thanks Wilbur,
I am doing that now, and have been using that curve in the past.
Would like to see how it sounds with just the low freqs filtered.
I cannot find the microphone AGC in Win 10 at all. Anybody know where to look?
Thanks and God Bless,
Wayne

Hello Ansat, Thank you all the good information you provided on the forums. I was hoping you can take a look at my files. I purchased the full version of Dirac Live because the LE version was lacking bass. I loaded your mic calibration and the subwoofer target curve with +8 boost and the difference was incredible, the bass is back! But I'm very new to this, so for the rest of the speakers I performed the automatic targeting. I want to get your advice on how it currently is and if there are any improvements I can make? Thank you! My speakers are: SVS Ultra Bookshelves LCR Hsu ULS-15 MK2 Sub Yamaha NS-IW280C ceiling surrounds      |
