That method there produces some fine minimum phase filters using inversion. It's the best I have been able to come up with, plus it's relatively simple to execute.

If you make correction filters from vector average responses instead of dB or RMS responses, there will always be differences because the vector average is not a true representation of magnitude like a dB or RMS average is.

My response featured a typo, which I have fixed. It said that FDW will ignore the dips. What I meant to say was that the FDW will not ignore the dips. We don't want those dips included in the FDW calculations. Acourate's psychoacoustic treatment removes them prior to applying FDW. The only way...

The problem with FDW in Room EQ Wizard is that it is applied without a psychoacoustic treatment ahead of it. This may be appropriate in certain situations but if the goal is to generate perceptually accurate acoustic correction, you have to apply a psychoacoustic treatment to the response ahead...

Typically I avoid boosting anything in the filter. Try lowering your target or adding more EQ bands. Either that or, if you use a computer to run audio, follow my guide. You can add a small bump (low shelf) in the target if you'd like. https://nverxion.wixsite.com/meridiansoundworks/drc-rew

No difference at all? That's strange. What does your system configuration look like?

I think the spectrograms look "worse" because the range is shifting based on the highest SPL in the measurement. It looks like the whole thing is being shifted up (toward the screen) as the bass peaks are attenuated with the filter. Notice how the scale on the right changes when you switch...

Interesting. With the setup I use (the one I typed up in the guide) I haven't needed to use that feature. Everything works great. I'll look into this, though. Nice to know there's another option hidden in there.

It looks like your traps are mostly effective from 160Hz and up. They aren't doing much below that. Either they aren't thick enough, they aren't in the right places, or there isn't a large enough air gap behind them. Not sure what the case is. There is a large reflection in the ETC graph around...

You should look into using Voicemeeter (either Banana or Potato) and a VST plugin host like Hang Loose to run your system audio. I have written a guide demonstrating how to configure a system with these tools. https://nverxion.wixsite.com/meridiansoundworks/resources/systemwideasioforwindows

If you do decide to follow my tutorial, my recommendation in the target design section is to place the target level somewhere between 69dB and 72dB, which is specific to your measurements. You will need to ignore the deep dip around 110Hz, which is a boundary interference null.

It's probably much better to do an inversion, but that requires convolution. Are you are implementing the filters as data typed into an equalizer? Or are you using impulse responses in a convolver? I haven't used Equalizer APO in ages, but I know it can do both.

Right on, so update your version of REW and it should be alright.

@JStewart You are probably very used to the way your speakers sound. The response seems flat enough to warrant that. Dirac has a proprietary way of handling the top frequencies. It is very odd, what it does. I can't really explain it but I have measured the filters it generates. They seem...

Thanks for clarifying, but for some reason I'm unable to replicate what you have there. I'm not sure what's different here.
