Why don't more recordings have soundstage outside of speakers


I always enjoy it when the recording has mixing that the instruments are well outside of the speakers.  I think it's really cool and what justifying spending extra dollars for the sound.  I just wish more recordings would do that.  Most of them would just have the sound from in between the speakers.

What are some of your favorite recordings that have an enveloping soundstage well outside of the speakers?

My speakers are relatively good but average good speakers....They sold around 1000 bucks 20 years ago....my system actual value is 500 bucks....😊



Mission Cyrus 781...On my desk with amplifier Sansui AU 7700 and a low cost french design Nos Dac ...This is good gear but nothing miraculous here which will explain my S.Q. by itself...


Then i eliminated the speaker exceptional design factor..... It is easy to buy speakers on par or better than mine....I already own for 40 years Tannoy Gold which were better high quality speakers but never sound better than my Mission because i was knowing nothing about audio at these times save plug and play....






Most of my recording has a soundstage variation and a depth imaging variation for sure.... BUT NOW the majority of my classical and jazz albums own a DETPH IMAGING out of the speakers front-back or /and sounsdstage outside of the speakers to a varying degree.... Very few have a sound between the speakers only....( i own around or a bit less than 10,000 albums)

And this fact is true for my 2 listening positions....Nearfield (3 feet) or regular position (8feet) my room is 13 feet square with a very bad position for the speakers with one in the corner of a wall a few inches of it....Then positioning is not ideal....😁


Then WHY this is so about my S.Q.?

3 reasons :

Controls of vibrations, control of electrical noise floor,
And the main one is material passive appropriate treatment (homemade) and ESPECIALLY the main reason is acoustic active control of all the room with an Helmholtz resonators grid, i called that a mechanical equalizer (homemade)....

Then in a word, with relatively any good speakers if you use ACOUSTIC basic science you will have almost all the time like me a depth imaging and most of the times an orchestra filling the room in varying degree according to the genius of the recording engineeer....

But the files i own with sound only between speakers 2-d are around 10 %....In classical and jazz....Then it is not your audio system nor speakers the problem probably, save if one of the piece of gear is a very bad design.....It is lack of acoustic control...

And acoustic control is NOT material passive treatment by the way...Passive material treatment with a right balance between diffusive absorbing and reflecting surface is necessary but it is only the HALF of the acoustic story....

Acoustic control of room is the most underestimated factor in all audio...

Why?

Because it takes a dedicated room, The Helmholtz resonators grid must be SPECIFICALLY fine tuned and tailor made for each specifics Speakers/room....Then no sellers of acoustic panels had any interest, after or before selling you costly panels, to prevent and inform you that their panels is not enough....

And anyway people boast about their costly miraculous design gear not about acoustic....

And many attribute to their electronic design the reason which is not false but only HALF truth.... The missing part of this truth is the more important one : ACOUSTIC.....

Especially for low cost system acoustic is the main lever to upgrade astonishingly your system.....Those who own costly system live anyeway with the impression that their system already so good dont need acoustic control.... This is false but how can you convince someone with 6 figures speakers than it will be better with acoustic control ?

A costly system without acoustic control is like formula one car on ordinary tire..... Go on the internet and listen some costly system, some are way better than others and acoustic is always the secret passed a certain price point....


Andy2-  the Pink Floyd record you are referring to just like the Roger Waters Amused to death is recorded with some of the microphones used out of phase. This is what the refer to as Q sound recording. This gives a surround sound effect with two channel. If you Google “Q sound” there is a lot on this and there are lists of albums recorded like this. 
Other than this I’d say back to system and room setup.  A very good recording helps. 
..get a better system....   
amusiced to death has sounds coming from behind, above, the next street to the right and left.
