Does 'envelopment' exist? Can it be measured?

[Sokel]

Forgive the intrusion, but would really appreciate your input. I am working on creating a multi-channel multi-subs system, with Schiit SYN in the chain.

The core is a pair of LS50 as main front / high, with one pair of "basstand MBM" bandpassed to extend / reinforce the LF content in stereo. Setting aside their top crossover for now, I'm thinking / hoping they will also deliver decent SPL down below 80-90Hz

I am also skeptical of that content being fully non-directional at an arbitrary hard-edged bright-line frequency

Therefore, I am considering also using a third **stereo pair** designed for "true subwoofer" bandwidth content*

I may also add one or more **mono-fed** sub boxen with placement flexibility to help with room modes.

So finally, my questions, for anyone, including any feedback welcome on the above

1. Where in the spectrum do YOU think the crossover should be between the stereo sub pair, and the mono "true sub" lower down?

In order for me to test listen and measure to make my own decision on the above in my listening spaces (including outdoors)

2. Can you recommend vanilla 2-channel source content (prefer music, but maybe also films) with plenty of LF recorded **in stereo** well below where most engineers sum to mono?

Synthesized test signals too I suppose.

*down to ~20Hz or even lower if possible, for films and also subsonic content in music, say from pipe organ, big drums and cello / double bass.

All the answers you want are probably here, along with test files and music with stereo bass:

Bass and subwoofers

This is the second in a series of follow-up posts to https://www.audiosciencereview.com/...-of-lokki-bech-toole-et-al.27540/#post-950580, this time focussing on bass perception with a brief digression on subwoofers, since there's relevance to (reproduction of) concert hall acoustics. I’ve...

Given your question, I would recommend Dirac ART. Will save you hundreds of hours going the other route. Trying to do all that manual is a pure waste of time. Don't have a chance doing it the same way for the most part. Few that can have like 10 subs and more and custom DSP.

Most engineers don't sum to mono.

Where the sell goes

Sorry is that a typo?

My point is, that playback technology can attempt to ADD an increased perception of envelopment after the fact

regardless of live vs studio, the space used, the intent or artistry of those who produced the recording.

For those not dogmatic purists, such attempts may be worth testing to see if you enjoy the effects or not, even if their success varies widely by the specific source material.

OK, but I have not found many recordings where there is significant separation between channels in the low frequencies.

I did come across a recommended album featuring a cello duo but I didn't write it down an now can't find it :-(

Not typo, just painfully bad english I guess.
I mean "where the sell happens", does that makes more sense?

No I extract no meaning out of that. Implies marketing / sales (lying)?

Maybe try rewording your intended meaning in an overall context, as literally as possible, and include your original language wording as well?

Thanks will add to my list of threads that need close parsing

If you are addressing me, thanks but way above my pay grade, my whole system will need to cost less than what many here have spent just on their turntable

Not addressed to you at all. We all have to live with what we got.

I see you are quite vocal - but unfortunately in this world it depends on hardware you have and less on your skills. I did not catch your drift on the other posts - can you explain it in simple English, like for children - just to make sure I understand.

One more try:
That's where the studio presents and sells the work to the artists.
No lying, no deceit, they just decide if it's worth paying for it and by that that's their intended artistic expression and sound.

Aha thanks now I see, thanks

No, you would need to google the terminology if the issue is your own knowledge base, or search / view old threads here.

If a bit of my writing is unclear then quote the part you did not grok, as I just did with Sokel and I will try to clarify.

Lol, comes with a hot spice...

Your writing and probably thought process is unclear and if you can't make a point then it is all you get. I don't understand a single word of what you posted, and have been around for a while. Perhaps other members can be more intuitive, but as far as I am concerned, nothing really warrants to engage all the brain cells, just because your cant express/write your concern.

Final is that this is IMO really poor POV for a member that would strive to gain some credibility.
