Harman EQ For Audeze LCD-3 (Fazor)

If I got an Audeze LCD-3 (Fazor) and requested its measured frequency response chart from Audeze, would it be possible to create a Harman Curve EQ for it based off the chart?

Does Audeze supply a "data containing" file (containing mathematical data points) or just a "printed" file (eg a PDF)? That is, can it be mathematically processed, or only inspected by eye?

Before I purchase, I want to ensure I can EQ the LCD-3F.

The oratory1990 LCD-3 preset doesn't mention anything about Fazor, so I'm not relying on it being relevant for current LCD-3's.

On another note, I only really want the LCD-3 over the LCD-2 for its look. I understand the LCD-2 (Fazor) has less unit-unit variation in frequency response, so would the LCD-2F be a better buy?

The LCD-3 I measured was indeed one with the Fazor (serial number 2821432)
Hi oratory1990, I acquired from Audeze the frequency response charts (Neumann KU 100) for my 2021 LCD-3 and the LCD-3 that you measured.

When I EQ my LCD-3 with your preset I think it doesn't sound quite neutral.

Is it possible to - although these are not GRAS measurements - adjust my EQ based on the difference between these two graphs? If so, could you possibly help me with it?

My LCD-3 is the top one, the LCD-3 you measured is below it. As you can see they are very different.

Here are the two graphs from Audeze digitized and overlaid:

Here's the difference between them:

Here's oratory's KEMAR frequency reponse of his unit:

Apply the difference to that measurement and you get the theoretical frequency response of your unit on oratory's KEMAR:

I've plugged that into the AutoEQ script and attached the resulting EQ settings to this post. Results for both Harman AE/OE2018 and for the AutoEQ target (Harman minus 2dB bass) are provided. PEQ sample rate is 44.1KHz.

Thanks very much, highly appreciated. I like that you showed your working.

Just one thing, I notice in your attached image of the correction EQ there are a few dips in the equalized frequency response, but most critically the dip between 4 and 5 kHz. Is that significant? I'm surprised that is there after the script.

it is not recommended to make deep, high Q corrections at high frequencies. That's why AutoEQ will not correct troughs there completely. It is by design.

Interesting. I suppose this means my Audeze unit is inferior to the one Oratory measured. Well I'll probably just live with it
