Help with my Audeze LCD2 Frequency chart

Hello!

I have tried many of the preconceived parametric EQs but none have convinced me, some are horrendous.

Rechecking my frequency chart I have seen that none of the ones shown in the AutoEq / github list do not look like the answer from my Audeze.

I can't find any card in that list with such flat measurements and those drops in the acute zone.

I have written to Audeze to gather more information and they have answered me this:
“To the best of my knowledge, that serial appears to be an LCD-2 Rosewood, Rev2 (post-2011) pre-fazor model.”

Can some charitable soul help me in this matter and find a Parametric EQs that can be applied to the attached photo?

Regards!

You could play with 2k (narrow), 4k (wide) and 6k (super narrow) - I think adding a few dB to each should help. I would ignore the 9k, as per Amir that area is unreliable in measurements so EQing might do more harm than good.

First of all, we need to know what target curve you're looking for.

I believe that the AutoEQ presets are more or less based on the Harman target. Have you heard that before from a different headphone?

Shelf the highs +5dB from 1kHz upwards.
Add some low bass shelf to taste.
Work from there. There is no one fits all EQ and all of them are kind of wrong.

Yes, the Harman target is OK.

Alright, just eyeballing it, here's goes...

That FR chart looks like it's diffuse field compensated. DF has quite a bit more treble than the Harman curve so we don't need to shelve it up all the way to be level than the bass and lower mids. Lets start with:

High Shelf +4dB 2.5khz Q .5

Next we need to bring the bass up:

Low shelf +5db 100hz Q .8

Next there are a few small peaks in the treble to knock down.

You could go a little more precise and start with:

Peak -5db 12Khz Q 4
Peak -4.5db 7.3Khz Q 4
Peak -3db 5.2Khz Q 3.5

You could run your FR chart through a curve tracer, import into REW or something, and come up with something super precise, but IME going for too "surgical" of an EQ on headphones is counterproductive due to all the confounding factors.

If it sounds too dull, try playing with the peak filters, increasing the Q or raising the gain. Then increase the gain on the shelf filter.

If it sounds too bright, decrease the Q and lower the gain on the peaks. Then decrease the gain on the shelf filter.

Thank’s!

These guidelines have helped me better understand eq.

does this eyeballed EQ apply to all LCD-2 series? as i am considering to get the Classic version.

In very broad strokes

The low and high shelves should probably be good for most of them, but each individual headphone (Audeze Lottery and all...) will have it's own individual peaks which will need to pushed down so it's not too bright after applying the high shelf.

Audeze has quite a reputation of variation from sample to sample.

Check out @solderdude's compilation of Tyll Hertsens Innerfidelity measurements. There are several samples of many Audeze models. Compare them to the multiple samples of the HD800, and even the original HD800 to the HD800S.

I have tried all the equalizations that exist and none of them work.

Now I have tried this one of my harvest and compared to the others it is wonderful!
Win by a landslide in bass, clarity and soundstage!

If anyone thinks that it can be improved, please contribute your ideas, always taking into account the letter I showed in the first post.

That is very precise. Did you find that as someone's suggestion, or create it yourself?

I have created it myself, noting how they solve the problems amirm, innerfidelity, crinacle, etc... i have looked at my cart and tried to compensate with a touch of my personal tastes.
I am a professional lyric musician, but I consider myself multidisciplinary.
I like to listen to all kinds of music ... the good kind. Obviously my preference is opera and classic music.

With this equalization the orchestral music improves a lot, but with songs like the following one it is a scandal !!

Sounds like you've got it then. :)

+3db to 3.5k, make it wide so it's around +1 at 2k and dont leak above 6k.

Additionally bass shelf depends on your taste, listening loudness. Keep the bass shelf below 200 or even 150hz.

Imo lcd 2 tonality should be fine. Its audeze house sound without big quirks like older lcd x or 2c.
