OK - They sound like nothing. No coloration. Flat. They simply allow the source to come through with remarkable fidelity. You hear the source - not the monitors.
All monitors have coloration. The Neumanns have directivity issues in the vertical axis due to their line source design, and all speakers have very differing directivity. Even two speakers that measure exactly the same on axis can sound completely different when placed in room if they have differing directivity. The Neumann's are one of the most accurate speakers on the market in their class and in general when it comes to frequency response, but it's doing a disservice to science to say that they have no coloration. It's untrue.

That's what estimated in-room response is for, and Amir made in his test a far field simulation. Not sure where's the coloration there, and sitting closer would make it even better.
 
I have seven pairs of Neumann monitors in my studio. The do indeed have a family sound - flat frequency response and low distortion. They are designed to not impart any color, sweetness, heaviness or anything else to the source.
If you had to choose one model of the 3, which one would it be?Judging ability to reach low, lower distortion, flatter response and lower IMD.kh310,kh150,kh120II?Any song that you usually use as a reference when judging a monitor?Thank you.

KH 150's.

I don't know whether colouration is the right word, uncoloured speakers still sounding different is imho a valid statement.

I would say that the far field in-room response doesn't fully capture what a speaker sounds like. With musical signal, the reflections you are getting from the room come from a moment in the track that is earlier than what you get from the speaker directly. That is what makes wide and narrow directive speakers with similar on-axis in room response sound different, the proportion of direct and indirect sound power, and the timing offset of those signals.

Imho, there's probably a dead zone between near field and far field listening where the indirect sound power is too much for a near field listening experience to sound excellent and too little for a far field listening experience to sound excellent and that's what @teashea is running into. In other words, they are expecting a flat response with a lot of room and not getting that.

There are probably ways to compensate for this, either through speaker placement, or through DSP (I'm thinking of specialization algorithms, not EQ), or both. There could also be personal taste involved.

I think Neumann monitors look quite good in a studio. View attachment 382882

Is that how you have your Neumann monitors set up in your studio while in use, positioned in neat straight lines without any toe-in adjustments?

In the manuals, Neumann recommends that their speakers be pointed straight on-axis to the listener, and I think only small adjustment to that would be needed for fine-tuning the high-frequency and transient response.

Don't you have any acoustic treatment other than a rug on the floor? That must be unusual for a music studio.

From my experience, on-axis alignment is really good. I have my KH310 firing pretty much on-axis with apex just behind my head at the main listening position. It sounds really good this way, and treble is just right for me.

I have my ATC speakers toe-in set up the same way as you, with the apex point about 15-20 cm behind my head. I think that gives me the best overall balanced sound with the right amount of treble “bite”.

When I finish a session, I point them straight ahead - just for aesthetics. When in use, I point them at the LP. As far as acoustic treatment, here is some info and photos:

This is my home studio - TES Productions - also known as the Meadowlarklabel. It is not commercial in the sense that over 16 years I have never charged an artist for a production.

My approach is quite different that anyone else I have seen. Instead of consolidating things into one workstation, I like to have separate workstations for different productions/functions. Thus in this room Ihave the three primary workstations.

Ialso have eleven separate workstations for my keyboards - a fewphotos below. Most of my productions now are keyboard based -primarily smooth jazz at this time. But I also do country, pop andsome hip hop.

As far as acoustics go, there is considerable attention to this, which I consider critical. The most important thing is the monitors and theirsetup. As you see, all of my primary monitors are Neumann (KH310's,KH150's, KH750, KH120A's and KH120 II's. These are all used in verynearfield mode - 1 to 1.2 meters from the listening position.

They are positioned from the front walls to avoid detrimental reflections. Since these are all in very nearfield use, the secondary reflections are relatively small compared to the direct sound.

There is some false information on the internet saying that there should beno room reflections. This is incorrect. A complete dead room would sound quite - dead. I room must have some reflections to allow the source music to be natural.

Next, all of the monitors are within one foot of the front wall. Since sound (in air) moves at the speed of one foot per ms. So the difference in timing between the direct sound and reflected sound is2 ms. As you know, it has been shown that one cannot distinguish two signals are less than 6 ms.

On the other hand, the reflections from the ceiling has a difference of about 110 ms, which is perceived an interference and not good. However the dispersion patters of these Neumann monitors are narrow. The loudness of the ceiling reflections are far less than the direct sound (very nearfield advantage).

Theside wall reflections are mostly greater than 20 ms. Reflections ofthis timing are perceived as echoes/reverb, not as interference. Andas mentioned above, to some significant degree this is desirable.

The back wall of the room is 50 feet away, with lots of furniture and objects that disperse the sound.

There are also heavy curtains behind each of the workstations and bas straps in the rear corners.

Bass is, as usual, the most difficult issue. The size of the room, which had opening of 8 and 9 feet are generally not a problem. One reason is that in every one of my productions, I cut off the frequencies below 45 Hz.

I have also attached some photos of the room. You can see that the large openings are there to dissipate reflected waves.

I also use the MA1 Neumann system, which makes adjustments for room acoustics.

Bu tI will repeat myself again - using very nearfield monitors completely changes the game.

I appreciate your inquiry.

If I understand correctly, an audio interface is needed to use MA-1. What would be a reasonable device..?
For reference - The best source of information/measurements on audio interfaces (by far) is the YT channel of Julian Krause. Personally I have chosen SSL and Audient audio interfaces. There are issues of functionality for a recording studio as well as quality of the conversion. Conversion quality is much less of an issue than ten year ago. Since then, developments in converter chips have resulting in many moderate converters having quality which make any issues like distortion of non-flat frequency response substantially below audibility.
 
Hello, everyone! KH150 and KH310 are close in price, which is more suitable for family music (more classical music)? Or wait for the new KH310?
What listening distance? These are not for farfield listening.
 
Who says that? One KH 750 DSP limits system SPL for both KH 150 and KH 310. It does not limit system SPL when used with a pair of KH 120 and enhances it with a pair of KH 80.
Neumann says this for equal output.
 
HI very interesting Do they tell also why maybe?
This is a very important point
I hope that is a statement not driven by sales Of course not they are German
I saw an interesting report on behavior of people from different countries
The Germans were the most uncomfortable in telling lies
I was amazed by that
In some parts of my country people seem to experience a strange pleasure when they lie
Especially politicians
Watch the Neumann YT videos on the KH150 where they explain this.
 
Really? Where did they say that? And was it a specific use case or context? Matching SPL capabilities?
The Neumann YT KH150 videos..... It is a clean statement not limited to any specific context.
 
Thanks I was going from what was said in the Neumann video.

A popular and frequently recommended combination is to add a single KH 750 to the 310s so maybe in practise it is not such an issue? I believe Neumann themselves recommend this combination. Just seems a bit strange that this would apply to the 150 and not the 310.
I have a pair of KH 310's with a KH750 and two pairs of KH 150's. The KH 150's play louder than KH 310's.

I don't want to get too off topic but I would say the opposite is true. Neumann's reputation and renown comes from their microphones, and some of their microphones are highly coveted or even industry standard in some applications (u87 for example- almost every studio worth its salt is expected to have one). By modern standards mics such as these often represent poor value for money and exemplifies the phenomenon of older microphones riding the coattails of former success and legend from recording artists and engineers. That design in particular has had minimal changes in 50 years and frankly speaking there are a number of mics from many manufacturers that are probably objectively or even subjectively better to use in a situation where many classic microphones might still be used because of reputation or availability. And they could even be cheaper and just as robustly constructed.

On the other hand, Neumann's monitors are objectively top performers across the board in every product category they offer, and in some metrics on par or even better value for money compared to Genelec at certain price points and geographic locations. It's fair to say than in modern times, Neumann monitors are more or less an undisputed "top 2" performer, just edged out by Genelec in some regards. In the space of high-end studio monitors there are much fewer options: usually you are deciding between Genelec or Neumann or even what tier of product you want from these two brands, so it is clear Neumann is its strongest in that industry being at least a #2 contender. With microphones there may be up to a dozen reasonable choices from half a dozen brands for a particular use case, so Neumann's strength is not as obvious, at least in modern times.
Good points. In my studio I have Neumann monitors, preamps, microphones and headphones. All are recognized as top quality. More importantly (to the present thread), the KH 150 are to best nearfield monitors made by anyone.
 
Thanks for the effort!

So, exactly the same experiences...
Reading the link you shared, one conclusion is basically that the D/A conversion in the speakers is subpar and could better be handled by a superior DAC before the speakers.
That's disappointing, especially for the price and give more cable clutter.

Another thing that I could try is use RCA out on the Bluesound and use the inferior Bluesound DAC for the D/A conversion and hear how that sounds...
To be meaningful there would have to be valid measurements or a valid double blind test.
