Neumann KH80 & Nubert X3000
🕑 Added 2023-05-07 09:11:07 +0000 UTCPlease listen with my previous X-EQs for the HD600 and HD58X to get the "right" sound.
Below you can see the KH80 placed in my living room as shown stock (grey) and equalized in black. Averaged RTA measurements with moving microphone at listening position.(unsmoothened).:
With psychoacoustic smoothin:g:
I will use this as reference for optimising my headphone target. I have a first result for the HD58X finished, which I will post later or tomorrow. I need to do some further tests, but it sounds very close to the speakers and should represent "neutral" for a headphone as well as possible. I will share more details soon, so stay tuned.
Meanwhile I also optimised my settings for the X3000 based on this setup, in this video they are still playing with my old settings which honestly are not that great. I had to apply the HP-filter to 50hz in order to get rid of the heavy bass peak, but thanks to this they sound way more natural now, despite the dips between 300-600Hz which I couldn't quite get rid of.

Ich glaube, wenn bei Kopfhörer der gemessene Frequenzgang ähnlich wie Fletcher-Munson-Kurven (Gehör richtige Lautstärke) aussieht, nimmt es der Mensch als neutral wahr. Wurde schon gut erreicht durch die Sennheiser HD600 Filter.

You can always add any tilt you like afterwards, but I need to get an as clean and flat noise-like spectrum as reference, to be able to reproduce this as pink noise in a headphone. If I get these 2 as close as possible in timbre, because it’s nearly impossible to get them exactly equal, then you can add any coloration you like, more bass, more treble to any amount you like. The key point is to have a neutral reference which in my case was approached in this particular room, but I demonstrated in the video how close the sound of the speakers can be brought to the original recording. Listening in other rooms gets you a different ambience, but if the speakers are equalised to flat the overall spectrum should not sound that different, these are rather nuances masked by other variables. I am quite satisfied with the result and the headphone still sounds really comparable to the KH80 when placed in another room.
Thanks for the response. Isn’t the conventional thinking that a speaker would be measured with a slight downward tilt in a regular room? As to not sound overly bright?

It’s a regular room as most are listening to music in regular rooms. I placed the speakers nearfield and more in the room Center to avoid too much added wall reflections and equalised the given response to flat as good as possible, I also tried other rooms but the final result would be pretty similar as long as one is sitting exactly in the stereo triangle. As soon as you move too much forward or back or turn your head to the side the response will change of course but I tried to achieve the response that one would get when listening to neutral speakers at ear height sitting exactly in the sweet spot with some slight averaging. I also have optional versions with more averaging which I will also post.
Since you’re going for a fairly flat response according to the measurement, is your room considered “dead” or anechoic? Or is the flat response in a regular room what you’re trying to achieve?
