Geithain RL 901K vs Neumann KH420

I think you missed the post where i compared all these speakers! Geithain vs Neumann side by side. The Geithain made the neumann’s sound like they had a head cold and have been smoking for 20 years…
If you get a chance hear the difference!
Already this is raising alarm bells for exaggeration and unreliable review for me…

The Neumann’s are objectively in the top 5% of speakers measured here, only a couple genelecs KEFs and Revels are possibly edging them out in their respective price classes. Diminishing returns is in full swing at the top 5%, any significant objective improvement would flood the market in that respective price class. In other words, I would believe some subtle/minor improvements over the KH420, but nothing is gonna be that obvious. I was trying to convey that minor improvements at this upper echelon of speakers are not worth it for me to go with a smaller or more obscure brand.

I could be wrong, but for these reasons it sounds far more likely your experience may change with a double blind test. At the very least, I think you will likely say these speakers are closer in performance than previously thought.
 
Nope! I am planning on ordering through local dealers in Europe, still talking to a couple to work out best shipping practice. (thanks for the advice on this, couldn't imagine shipping going bad!) deal should be buttoned up next week!
please share your experience with those local dealers. I'm thinking of getting a pair of 906 and basis 11k. Thanks

What raises my alarm bells is that you don’t even consider the impact that THE ROOM has on real life listening. This is not a straight up comparison of frequency response charts measured in free space!

No speaker you mention in comparison has a cardioid bass response.

It is very well established that cardioid bass response will lead to different SBIR. It is also well known that lower frequency build ups tend to cloud our perception of higher frequencies. When I turn Dirac Live off in my studio, bass nodes increase and overall clarity is reduced. This is easily heard in a blind test. There’s over 10dB difference in some frequencies so it’s hardly controversial.

Whilst subjective descriptions are always just that, the description of “head cold” to me means that there is some “congestion” masking out clarity.

That sounds like what id expect from a cardioid bass response vs a typical bass response IN A ROOM.

It won’t show up in a frequency response chart measured in free space. But most definitely will show up in a set of measurements taken at the listening position and would certainly be audible.

Its not hard to understand that a cardioid speaker reacts differently in a room. It is also well known that lower frequency build ups tend to cloud our perception of higher frequencies.

It won’t show up in a frequency response chart. But most definitely will in a set of measurements taken at the listening position. And it would most certainly be audible in many rooms.

It doesn’t take a double blind test to hear that in room responses are not the same as published free space frequency responses. Nor is it a stretch to understand that a cardioid response will interact with a room differently to a typical bass response.
I remain skeptical for multiple reasons.

Why wouldn’t it show up in the CEA 2034 measurements?

I think my point still stands, though. Different doesn’t necessarily mean better, I think that poster was implying distinctly better. If it was head n shoulders better than an already great speaker, why isn’t the market flooded with this speaker or other speakers w/ cardiod bass at this price point? Isn’t Dutch n Dutch 8c cardiod bass? Its a great speaker too, but certainly hasn’t swept the market.

If we are going to claim a totl 5000$ speaker (or really all speakers comprable to the KH420) are significantly outclassed, I need some hard data before I jump on the bandwagon.

CEA2034 does not predict SBIR. It contains a predicted in room response curve, which is an average of listening window, early reflections and sound power, in an imaginary room with zero boundary interference.

Whether that is relevant in a treated room, where the reflected component is often way down, is still arguable anyways.

But no. CEA2034 does not predict the way a speakers interaction with an actual room.

Cardioid reduces the effects of SBIR. SBIR reduces clarity. You won’t get it for $5,000.

Dutch&Dutch 8c have been doing pretty well. Ask Purity Audio.
 
technicalities and semantics aside…

None of this goes against or differs from the main point I was making. These possible benefits are so marginal that they are not worth chasing an expensive speaker made by an obscure company with little data demonstrating its supposed superiority. Still doubtful of an obvious audible benefit at all.

So we should put aside the technicality that SBIR is improved in cardioid, and put aside the technicality that SBIR impacts clarity, so that you can you can claim, with zero data, that SBIR is inaudible?

All you have is a belief that cardioid bass response is inaudible, based on some preconceived bias.

Theres plenty of threads you can find to refute that. Check out some measurement discussions by Sigberg Audio.

You should calm down…

Just pointing out the obvious diminishing returns, sensitive one. Never said it was inaudible, just likely not a transformative experience like you are claiming (also with a preconcieved bias)

There is lots of endless data to support this. The entire speaker market is not dominated by cardiod bass. Its a reasonable level of skepticism to say that this is not above and beyond all speakers that don’t have cardiod bass.

The hard data that shows up in CEA 2034 is low frequency DI. A cardioid will have LF directivity while a monopole will not. In a small room what that means is they drive room modes differently. I don’t know that one could say either is universally better. However, they should sound fairly different as a result.

No one has claimed “transformative experience” until you just said it :lol:

Incorrect. This has been the basis of every one of my responses here.

“Geithain vs Neumann side by side. The Geithain made the neumann’s sound like they had a head cold and have been smoking for 20 years…“

This to me sounds like a transformative difference.

I heared the Klein & Hummel O300 (direct ancestor of the Neumann KH310) in direct (but no abx) comparision with the Geithan 901K, and the Geitahn was slightly better in the bass. They were in the same space (a mastering studio) set to the same sweetspot for the engineer (i was repairing/reconfiguring his computer). But they are less far off each other than most assume here i think. But the measurments will show the truth objectivly, i'm talking subjective experiences of 20 years ago so...

I knew Klein & Hummel and they have been my favorite speakerbrand for longtime (even before that) since i know the O98 of a friend of my dad (mid 80's). That brand, before Senheiser bought it and renamed it Neumann, was also little known outside Europe even if it had a long history, like Geitham now. It has a similar history of a very high rated small German audio company that got bigger than they intended originally...

The differences between the speakers was veryyy audible to me. It is true the listening conditions were not ideal. In fact the neumann were closer together than the geithain so i had to move in the room to compare. Def not ideal. Anytime speakers aren’t in a free standing space issues happen, unfortunately creating these conditions for a perfect demo is difficult without spending a ton of money.

When i started this post i was advised to listen to these speakers because construction, materials ect. Have huge impact on sound.
I am eager to learn more on how the graphs provided in this forum correlate to audible perceived differences.

But to comment on neumann vs geithainn.
I felt sbir did have an effect on this listening experience. And it would likely have an affect in my own studio!(I’ve read the only way to overcome sbir in a meaningful way is soffit mounting, which in itself is expensive!)*i read this when doing some reading through the master handbook of acoustics

But also the overall impression of the speaker. I hear a lot of the “euphonic tuning” of the geithainn, the “natural presentation”. These things become pointed out when compared to a speaker like the neumann. More flat, more “speaker” sounding.
I could easily learn how to mix on the neumann and find great results. But i feel i would still be compensating for the imho less favorable “tone” of the speaker.
On top of this there was the what i found to be a haze or distortion in neumann that i can’t quite put my finger on… maybe an interaction between the drivers. Maybe the fact that they aren’t coaxial… maybeee sbir… not sure! This was confirmed though when my gf’s untrained ear picked up the difference right away.

But when i listened on Geithainn, like i said in previous posts, i was not only hearing the fundamental of the kick and bass but also in a very clear way the individual harmonics poking out. I could hear the beater of the kick and what material was used. I could hear the very gentle sub freq produced when the strings of a guitar were plucked. It was as if i was brought into the room the recording was made in. My experience with neumann was i was still listening to a loudspeaker. A very accurate loudspeaker! But a loud speaker. I have yamahas and aurtone for this. I want mains to give me more.

I understand geithain. Is out of reach for a lot of people (for many reasons) and that is likely why they aren’t more popular.

But my first question in my journey was, “should i look at measurements and accept great measurements for what they are without first demoing the speaker” that is why i was greatly considering the KH420 in my original post! If anything i had a confirmation bias toward these, as they are easier on my pocket!
The overwhelming response was LISTEN FIRST!! Same response in gearspace.
So i travel across the world to hear these speakers for myself.
My second question became between the speakers in this price point, which one do i like the most/ will be the most useful to me.
After comparing side by side, i came to these conclusions.

I really do hope we can get third party measurements on the Geithainn.
I also wish they were more available to the world.
But when i heard them i knew they were what i was looking for. Even compared to speakers in a higher price bracket. For me the RL901K checked every box and then some.

Huge sweet spot? ( and i mean kind of unbelievable likely do to coaxial) check
Low distortion figures that make the speaker feel effortless and natural? Check
A cardioid response down super low? Check
And all this WITHOUT DSP…
Is it the world’s best speaker? I don’t know…
Still haven’t heard the Genelec 8381A ;-)

I too believe in diminishing returns, to the everyday listener maybe the difference isn’t great enough to justify such a price gap. Imho, when you go from 80% to 95% something special happens… a sort of magic feeling happens. It is like getting a great croissant and enjoying it. Food is food, but when you go to france and eat a croissant made by the hand of a master who has dedicated their life to making something perfect, it translates to me, in an emotional way.
The little details add up… and why settle when these will be with me for the next 10-20 years?
Not to say i NEED this in anyway, but to me, in my very specific situation. I feel it is a great option!

I was indeed exaggerating! I was applying some humor. In reality neumann was a great speaker, indeed better than my current setup, but i heard limitations, therefor couldn’t choose it with confidence.

I genuinely believe the only reason geithain isn’t more popular is because for some reason i can’t put my finger on… they don’t care about marketing or expanding!
 
please share your experience with those local dealers. I'm thinking of getting a pair of 906 and basis 11k. Thanks
I certainly will! As soon as i narrow down which dealer i go through! Still emailing back and forth with a couple.
Are you looking to demo aswell?
 
In case it is helpful, though it has been posted before, i will include the data from Geithain’s website for the RL901K.

It really goes without saying but ensure you get something written from the dealer regarding warranty and any repairs.
With no local representative and the ( in my experience)companies completely unconcerned attitude.

Will do! This has been my main point of focus when talking with dealers. Definitely won’t settle on a deal that i feel is less than worth the price! Especially in regards to shipment insurance and warranty.
Thanks for the insight!
 
The issue might be a dealer selling out of area, some, many in fact manufacturers aren’t keen on that, but if there is now no official representation?
