Hi Thomas.
Out of curiosity what speakers did you originally treat your room to accommodate, and how are your new sealed box Magicos performing in your now treated space? ATB Peter
Oh yes, forgot to mention, can we have some more up to date photos of your room treatment endeavours please?! 
Apparently, if your not in the direct line of the speaker drivers - you would struggle to hear much. Certainly if you were behind them.
Sound seems a bit muted , not?
I feel you feel better now, I hope. Vs some days ago.
Yes thank you, now that xmas is but a memory.
I would imagine a hifi systems speakers in such an environment would be absolutely position critical. Depending on the dispersion characteristics. A hairs position of your head out would mess up the soundstage. 
I can’t imagine, have never been in such environment.
With my old company we used them for testing machinery noise levels, frequencies & harmonic patterns, but no person is present in the chamber during the tests, data is measured in the chamber & recorded in an outside control room.
Working in the large chamber was very disorientating during the time we installed equipment, the sound is very unnatural.
I hope we are still a bit in the topic…I imagine that an extreme acoustic treatment which would looks like a bit like this anechoic chamber would be the negative side . Not very natural or lively.
frenchrooster,…Such a room is an anechoic chamber,.so if you are not used to it,it can be experienced a bit uncomfortable to be in such a room.
You can experience a sweltering feeling.
My friend,.the acoustic and sound professor,permanently had a music-system in this room at the university.
I gave him advice on what cables he would have in that system 
.
He was able to conjure up fascinating musical effects from that music-system,just by changing the acoustics of the room.
One time we were eight people,who would sit exactly after each other from an exact point in this room.
He had changed the acoustics of the room,.so when he played an A Cappella-song.
So where we sat,.we felt that the singer’s mouth was 1 meter wide,and 40-50 cm in front of the face,.a fascinating experience.
So it is possible to “conjure” a lot with acoustics,.I personally have learned a lot from all these sound-experiments.
A knowledge that I have with me when I install systems.
Hope this gives you a picture of how these rooms work.

I don’t see the link here Peder. Experimenting such anechoic room and installing systems is different.
I don’t understand your point.
I hope you will comment as promised the link I posted on audiophile style review, on installing and set up of acoustic treatment. You said there is an error.
We have experimented a lot with different factors and acoustic conditions.
How things depend on each other,.or maybe counteracts each other
Without going into more details,.but this has increased my understanding,of how to fix problems that arise during a system-installation in a room.
/Peder🙂
It will probably depend to some extent on the speaker and how it is designed. A true anechoic chamber would be highly unpleasant to occupy in silence [Link]. I suspect that it wouldn’t seem great for music playing, at least not with most speakers, and if playing quietly the lack of normal room ambience would likely intrude. However, getting close to anechoic, in effect removing the room, can be highly beneficial, as I found and reported in another thread, linking early in this one but tge key part copied here for convenience:
The relation here should be easy to see.
The anechoic chamber example shows how the complete elimination of room effects - changes perception - much like the opposite, of a very lively reverberate room.
If you want to just hear the hifi.
IMO if you want to hear the music, some scaled down resemblances of naturally recorded material containing acoustic artefacts, that then have some resemblance to the acoustic artefacts of your room - should sound more real.
As well as the speaker design I guess it may also depend on the recording, particularly how much ambience it has. A good hifi system should just play the music and let you hear it. The problem with room effects is they then modify the sound, such that the music may sound different in every room, rather than sounding as it was laid down in the recording.
But as I said, totally anechoic may be an extreme and sound unnatural.
It’s a bit what I felt in some very treated rooms . The sound was very accurate on hifi terms, clear, soft, with no hardness. But something was missing. It lacked life and vibrancy. The sound was too homogeneous.
You were probably playing the wrong album.
If you played something inherently strongly recorded that was homogeneously clear, soft and no hardness. It would no doubt have sounded like whoever was recording it was just there in the room.
Nope, I went with a few favorite albums. The sound was a bit aseptic and sterile.
Sounds as if the listening end has been over damped in those rooms ( easily done). Also we all hear replayed music very differently ( something I always find a bit peculiar, but hey ) ATB Peter
Hi Peder.
Does this mean that you can make a system linear in its replay, without the help of acoustic treatment? ATB Peter
