Topic: PEQ for Grado 225x - ADI-2 DAC fs

Anyone with a picture of their PEQ setting for flat frequency response on remote for the 225x model. I’ve seen the Reddit page on this but can’t seem to find the x.

And besides, I’m not really sure how to put the displayed values on Reddit in to my remote in the Mac.

Re: PEQ for Grado 225x - ADI-2 DAC fs

If you have a PEQ table for these headphones, you can manually enter these numbers into the EQ PRESETS page of the ADI-2 REMOTE software. Then you can save it (DEVICE: STORE) as preset #1~20. Then, when you return to PH1/2 or PH3/4, you can select that preset as the current and turn on the PARAMETRIC EQ slider.

Thank you! That is so convenient. I hope someone has got a proven peq for them.

The Grado 225 has loads of iterations as you can see here:
https://github.com/jaakkopasanen/AutoEq … er/results

They seem to share more or less the same Grado-house-sound.

• So, select a small number of coarser/wider EQ bands from other 225 variants and listen what you get from them.

Absolutely ignore all:
• Narrow bands (high Q-factor), specially those above 2 kHz.
• Bands with low gain.

• Don’t overdo bass boosts, depending on listening level the bass might sound distorted due to driver reaching it’s mechanical limits.

ADI-2’s “Loudness” function is better suited for this purpose without triggering asking too much from the driver.

Thanks KaiS for the link!
This is an excellent database of measurements and EQs for almost everything that has been created in the world of headphones.

I will compare my current EQs to this GitHub database in Crinacle's Graph Comparison Tool (For Headphones)
https://crinacle.com/graphs/headphones/ … p;tool=711

In the meantime, I'm experimenting with the Equalizer APO tool in the Windows by temporarily disabling ADI-2 PEQs for outputs.
This way I can use the Graphic EQ text data to fill out the compensation curve. Without proper measurement equipment, I rely only on my ears and subjective impressions of familiar music to justify the benefits of this EQ over the ADI-2's built-in PEQ, if any.

Re: PEQ for Grado 225x - ADI-2 DAC fs

I have the Audeze LCD-X (2021). The link you posted I assume that bands 1 and 10 are obviously for bass and treble and 2 - 6 are for bands 1 - 5 on the ADI-2 Remote? Thanks for the link btw

That‘s what I’d try, ignore the bands in brackets, they are useless or even destructive to the sound.
ADI-2’s setting’s steps are a bit coarser, so use the ADI-2 values that are closest to the listed ones, and correct by taste.
