Would you recommend upgrading from the miniDSP 2x4 HD to the DDRC-24?

1. Lay out all your measurements in the same MDAT and apply 1/6 smoothing like this.
2. Zoom in to a sensible vertical scale (it is conventional to use about 50dB). With a suitable horizontal scale (here, 20Hz - 20kHz).
3. In the "All SPL" tab, click on the graphs you wish to compare. See the result for yourself. Red = Dirac on, Orange = Dirac off. No need for us to tell you

That must sound much much better with Dirac on than with Dirac off, right Musica?

 

[musica]

Yes, it sounds better with Dirac enabled, but I still can’t clearly distinguish the kicks from the bass, and the highs don’t stay fixed in the soundstage — they move as soon as I move my head. Am I doing something wrong?

 

[PeterNL]

Here is the REW file with the Dirac ON and OFF measurements. What exactly did Dirac correct?

Looks much better with Dirac ON.
Don't forget to set Dirac preamplifier on negative gain (something between -6 and -10dB) to prevent digital clipping. Dirac has boosted some frequencies a lot.

If the soundstage collapses as you move your head, then you have a room problem. Dirac can't fix sound differences between different locations in your room. For example, if one spot in your room has bass suck out but another spot in your room doesn't have the suckout at that same frequency, Dirac cannot fix that frequency at both spots simultaneously.

Sorry, I didn’t quite understand

Yes, but shouldn’t it remain stable inside the imaginary cube created around the head by the 9 measurement points taken with Dirac?

 

[PeterNL]

I don't use Minidsp but Dirac Live PC version but it should be somewhere here (RMS-Meter value, in this case from the picture -14dBFS):

The unstable highs: an unstable stereo image is normal, if the speakers and the room are not symmetrical.

Kicks vs Bass: a 2.1 listening setup?

yes 2.1

 

[musica]

My setup is concentrated, and the listening point is all focused in one corner of the room. The satellite speakers are 95 cm apart, the subwoofer is under the left speaker, and the listening point is 70–80 cm away from the speakers.

Tweeters at your ear level ?

Yes, but I can’t angle the speakers toward the listening point.

Now that's not good.
Have you experimented with a symmetrical listening position towards the corner?

What’s your source material and system list?

My system isn’t located in a corner of the room, but along one wall, in a small area of a 16-square-meter room.

 

[musica]

With Dirac, I aimed to achieve the Harman reference curve (the yellow one).
Did I do the right thing with the overlay/superimposition?

Looks good to me. Enjoy listening music.
