Showing results of EQ

[regtas43]

Amir, I am a big fan of your speaker reviews. I envy you the Kippel system and it is
great to see the results. But I would personally be really really interested in seeing the
results after you do your (often recommended) EQ. I applaud your willingness to
get in there and fix things with EQ. But I would really appreciate seeing measurements
after the EQ. I realize that we are dealing with linear systems here and in principle one
could figure out what the results would be. But visual presentation counts and showing
the results would be cool indeed, really inspiring in some cases.

You can download the data in the .zip file amir provides for each speaker review, load the data into VituixCAD, apply EQ, and see the resulting changes. Or even run the data through external scripts, as pierre does. You can see an example here:

Grimani Systems Rixos-L Review (Active DSP Speaker)

This is a review and detailed measurements of the Grimani Systems Rixos-L active DSP speaker. It was sent to me by the company and costs about USD $8,200. Speaker is designed to go into the walls or mounted on them and then covered by a screen for home theater applications. The former is...

The only thing VituixCAD won't show you is distortion results, because those are not present in the original data.

Which speaker do you want the response of after EQ?

 

[regtas43]

I was interested in for example the Polk T50. But actually I am interested in ALL of them.
Since many can be improved (as one supposes) by the EQ, it would be a big help to
the public if every time EQ was suggested, the results were shown.
Few people are going to want to figure this out for themselves! even though they
could. Thanks for considering this-- it really would help people and make the data
more useful to them.

Here is how you can use the REW EQ tool to show you how the response will be after EQ is applied.

Thank you. Very helpful. Robert G

Personally, I'll like to see the EQ changes in Rune, RME ADI-2 Pro confirmed with amir's testing rigs (his speakers and headphone reviews). I love the measurements and EQ recommendations. But d also like to know how close to the target curve his EQ gets.

hello,

you can find all of them (with and without EQ) here: https://pierreaubert.github.io/spinorama/
Click in a speaker and look at them side by side or go to the compare tab and compare them both on the same graph.

I think a point to note is that for fixing anechoic response to put it in your own treated space the rew pre and post estimation can make it work, but other than that, those of us who did eq ourselves highly likely just fix everything for our in room response and since the rooms are so much different from one another, the actual response showed after eq is of little reference use.

Is there a way on your site to find the actual EQ settings that were applied in case I wanted to try them out, say with an RME ADI-2? Looking at the KEF R5, specifically...

yes, go to the EQ tab at the top, look for your speaker.

Thx!

What if I want to generate my one set of filters to use with my RME DAC, which only has 5 PEQ bands plus high/low shelf? Can you give me a hint?

hello,

there a few ways to make it work:
- easy: take only the first five. they are in order of effectiveness (so you don’t loose much if you do not take the last ones)
- run the software. If you are an IT person, that should be easy, If not follow the README for installation and tell me if that works. Looking at the README, it doesn’t explain much the command line to use the optimiser. Note that it has been developed on Linux and tested on Linux and macOS but not on Windows.

export SPEAKER=“KEF R5”
./generate_peqs.py —help
this will give you the full list of options
./generate_peqs.py —speaker=“$SPEAKER” —max-peqs=5 —max-Q=3
should get you started. You will see a picture in ./docs/speakers/KEF R5 which describes the effect of the EQ on the spin.

I will add more explanations to the README doc in any case.
