So how does it sound, Shimei? Thinking about the SHD for room correction. I won't know until sometime late next week when I'll have a couple days to dedicate time for tuning. I'll be sure to update the thread!

So how does it sound, Shimei? Thinking about the SHD for room correction. Pretty dramatic difference. My PC is actually 36 feet from the system so I purchased extended USB cables........ but the microphone cable had the wrong end so I moved my PC closer because I just couldn't wait any longer. I ran the frequency sweep and saw the curve.... Dirac Live 3 adjusted and the clarity was just amazingly better. However, I don't like how much the subs are flattened out. I ordered another USB cable for the microphone so I can take more time and do multiple other microphone placements around the room without worrying about my wife complaining. The measurements are very sensitive towards background noise. I actually had to unplug the refrigerator and turn off the HVAC unit during testing. Just to note it seems this minidsp hardware and software has fought me each step. First, I updated the firmware only to turn the unit into a brick. But support was helpful in restoring the unit. I was informed the instructions were outdated and I didn't have to update the firmware. Then trying to run Dirac Live 3 was unsuccessful. Turns out my computer's network adapter and my router's DNS wasn't able to connect to Dirac servers. I used Cloudflare's private DNS of 1.1.1.1..... once changed to Google's DNS of 8.8.8.8 I was good to go. Looking forward to tweaking the system more.

Alright, finally have the system completed wiring wise. Used all XLR but for the subs instead of mixing balanced with unbalanced inputs outputs I used all balanced with an XLR to RCA adapter for the subwoofers. Here's some screen shots from within Dirac Live 3. I have some learning to do, like grouping Dirac channels etc which I haven't done yet. Here are the Left Right Center Sub 1 and Sub 2: FL: FR: C: SL: SR:

Trying a different Target curve as lots of people are recommending the NAD target curve. The full frequency NAD curve can be downloaded free from here: nadelectronics.com/dirac-live/The default Dirac target curve is rather flat and seemingly removes some of the life from the Tektons. The NAD curve boosts bass response. The bolded pink and blue lines are the corrected response:

I think the Dirac curve kills the life of the sound. Maybe for speakers that are too bright it would be better. Like, I could imagine my Klipsch sounding better.

They are available here: mehlau.net/audio/dirac-live-2/ I loaded the NAD in the preset 1 location and will be following up by loading the various Harman curves in the other three presets. What I like about the Dirac software is that I don't have to remeasure. Just measure once, save project. Then when applying different filters load the measurements back up and load different curves and it generates the proper filter to export to the device. I'm stoked that this hardware/software is so easy to use!

I'm stoked that this hardware/software is so easy to use! I agree that only having to measure once is a wonderful thing. I would suggest you consider leaving the bass boost as is in the NAD curve, but flattening the curve out for the higher frequencies so the correction continues flat to say 24Khz. I think the attenuation in the higher frequencies in the curve you posted and in the standard Dirac curve make the sound compressed. The 4db, 6db and 8db Harman curves are great if you remove the high frequency cut. If you have a sealed subwoofer that can respond below 10Hz you also might consider removing any curtain below 10Hz and taking the bass boost (whether 4,6, or 8db) all the way out. I have Kreisel DXD12012 subs and that is what Ken Kreisel suggested. I do not think that would be a good idea with ported subs though.

I did note the high frequency cutoff "curtain" and extended its maximum. I'll give the NAD curve some time listening. The Beryllium tweeters I swapped in place of the stock softdomes were a little bright before implementing Dirac...... I'll play with the subwoofers some other time when tweaking/listening to the Harman curve..... and yes I have two Tekton 4-10 subwoofers which are sealed. Much appreciate your feedback! Enjoy, William

Enjoy, William Thanks. I wanted to mention that Dirac has great potential in improving timbre matching between various speakers. I think Atmos will benefit greatly from Dirac.

The NAD curve boosts bass response. The bolded pink and blue lines are the corrected response: I think you might try dropping your entire curve by 2 or 3db. Dirac is much better at pulling down peaks than boosting dips. It is all a compromise, of course. Dropping the curve will probably help you at around 40Hz, but it might not work as well as it is working between 100Hz and 200Hz. Might be worth the time to experiment.

First, I had the crossovers set in the output tab rather than LFE tab. The subs are now much smoother during Dirac measurements. If I understand correctly setting the XO in the LFE tab won't effect the measurements but setting them in the Output tab will.

The NAD curve in the above screen shot over exaggerates the bass wayyyy too much and over drives the center channel to the point where the curve needs be flattened or the XO point passed higher up. So far the Harman 6db curve suits me best.

I think I have the 4 db on everything except the sub which is 6. I pulled down a few areas where I had dips as to not have any boost happening.

I pulled down a few areas where I had dips as to not have any boost happening. I'll try that Harman curve mixture. I actually loaded one preset with Harman 4db curve and the NAD curve for the subs. I've not listened to it yet because of the hour but I'm sure it's going to be way too bass heavy.

I've not listened to it yet because of the hour but I'm sure it's going to be way too bass heavy. the main reason I picked the 6 was because the subs we already there if that makes sense. After all my changes, my sub spl was roughly 6-7 db higher. It just kinda made sense to use that curve and just follow any dips down so I didn't clip the amp trying to boost those dips.

Makes sense to me. I'm compensating for mixed balanced and unbalanced outputs. My active subs don't have XLR but only RCA so I'm using an XLR to RCA adapter on the Minidsp's XLR outputs to the subs. A 2db boost to the subs to compensate for the gain difference is bout right. I guess I could compensate by adjusting the gains too but this will do also.

That bass lift in the target curve looks like about 2.5 db/octave starting at 200 hz, same as my 2ch. But I don't have any dips lifted, so My Maggie 3.6/Rs roll off naturally within that envelop.
I'm sure your speakers are capable of stentorian bass......
I start the treble decline at 1khz, at 1db/octave to 20khz.

I found that if I reverted to no filtering above 100hz (shrunk my curtain to sub 100hz) the Tektons are free to do their thing and they sound great. I think however Eric does his magic it is best left to him. That is my personal view based on my room and speakers, your results may be different based on your preferences.

I know the Tektons are great but the real world living area isn't an anechoic chamber where the Tektons shine the best. I'm sure the in room frequency response in my measurements look nothing like Tekton Ulfberhts in an anechoic chamber. Wish I had that graph too though! The room is actually what I've been dealing with for months now. First by sound absorption panels, refraction, and now by DSP. I realize I have a lot to learn with room correction. Tis my first few days so I'm still teething. Much appreciate your advice and suggestions Mark. Enjoy,William
