Now That Atmos Is Everywhere… Real vs. Phantom Center in a 5.1 Music-Focused Setup

In all of the years I have been listening to movie soundtracks, I have never heard of bass "being in my head". Subwoofers that are positioned in the corners will give you all of the spaciousness you need. Besides, the other gentleman was talking about moving the bass around the room. I think you are talking about something different than he is.
 
Your argument on any possible negative room interactions in the surround bass range is the same that exists for any 2 ch system only somewhat exaggerated.

A perfect reason to use bookshelf speakers and a sub instead of full-range speakers.



OTOH the the gains made from the matching tonalities of all speakers more than makes up for it.
Tonality is not established at bass frequencies. It is established in the midrange and upper frequencies.

Having matching LF & LR is just as important as matching LF & RF .
Matching in tonality, yes. Not matching in size or frequency extension. That is not necessary, and neither is having 5 full-range speakers.

Listen to the youtube demonstration with headphones. It makes it really obvious what he is talking about. But he is also talking music, not movies.

I'm about 80% interested in listening to music.
I only watch the occasional movie and about half them are only in stereo.
 
All bass in movie soundtracks is mono. While there are interaural time difference down to 20Hz, the ability to hear it becomes weak below 80Hz. There is also interaural level difference, but they are also weak at low frequencies as a result of the long wavelengths of bass frequencies. Recording stereo bass is a waste of time because of these reasons.
"Soundmixer". :facepalm:

I don't know where this believe, that bass in mono was something to strive for, comes from. Or that professional setups would work with bass in mono.
Movement in the bass is fun and is sounding great!



This is the image over frequency, only between the surround channels, of a recent movie:

Is that enough full spectrum dominance and stereo bass in the surrounds?

Even for stereo mixes, where mono-compatibility always has been important, since the late 1990s, effects, like for example the Waves S1 shuffling, have been used for all kinds of (intentionally exaggerated) bassy stereo fx, flybys or reverberated bigroom kicks that spread out, mostly on intros/interludes in EDM. On headphones these effects are creating a nice unusual pressure difference between the ears, especially if it goes lower. Stereo-Upmixers with surround speakers that are not monoized, can reproduce an increased sensation of width and depth in these situations (because these effects work with anti-phase, they are steering the surround channels strongly).

We are not talking about headphones; we are talking about speakers. Headphones were never brought up in this discussion. Whether talking about movie reproduction or music reproduction, the principle of getting good sound is the same.

Yes, I know. I referenced multiple articles regarding koudspeakers in a room. His demo lets you hear the effect easily with headphones. His research is how to get the same thing in a home that occurs naturally in a concert hall.
 
Sure it simply means you have no clue about mixing, are not a mixing engineer and you are regurgitating hifi-consumer-falsehoods.
This sounds to me like a personal attack, with a strong dose of ignorance attached. Let me ask you what mixing experience do you have that allows you to judge me? From what I have read, you have none whatsoever, which makes you unqualified to make such a determination. Maybe you should stick to what you know, which does not seem like a lot.

Pls, stop.
Why would I stop telling the truth? Do you really think a sound designer spends precious time mixing stereo bass when it is not audible on the dubbing stage, in a theater, or in the home?

You are making crap up, challenging what others do for a living (without knowing a dang thing about them), and you have not shown you have mixed cake batter. YOU should stop!

Five full-range speakers in a circle around you is not ideal. Each one of those speakers would be strongly interacting with the room boundaries very differently, and each would therefore have a different frequency response. The ideal setup would be compact speakers capable of high SPL crossed over to multiple subs at 80Hz. This would result in superb imaging and an even bass frequency response throughout the room.
Couple of thoughts…
5 full range speakers would work extremely well in a 5.0 system with Dirac ART IMO.
But bass managed systems can obviously sound great when done properly. While much of the research always seems to quote 80hz has nnot directional, crossovers are not brick walls and have always found a bit lower is better
Unlike studios who would be extremely carefully about selecting bookshelf speakers that can handle mid bass without compression or objectionable distortion, I think many home bookshelf speakers may struggle at high spl’s.

They'd better be big speakers with very powerful amps. I don't know many speakers that can reproduce the LFE channel without barfing up their parts. Without a sub, you are going to have to house curve your front L/R mains, and that puts a lot of stress on the amps and the woofers of the mains, not to mention reducing headroom and increasing distortion.

I don't think it is a good idea to exclude a subwoofer from a multichannel system.

Nothing can replace proper sub setup IMO and lot of perceived “bass directionality” comes from room resonances etc. Once you get to 4 subs placed properly around the room and use any advanced room correction method it is much less pronounced. Said that I prefer to go to 60Hz for L-C-R and 80Hz for surrounds/ceiling.

Re surrounds/ceiling speakers - I think good rule of thumb is to have them f-6 at 40Hz to heave enough headroom and cross them over at 80Hz.

And even more important is to have enough speakers, I think 9.x.4 as sweet spot for 1 row, 5.x.x is leaves just too much on the table re immersion. Even 7.1 for DTS HD MA is minimum.

I use 60 all around and have considered trying even lower but I am in the middle of changing processors and will wait till then.
I no longer enjoy tweaking about with things as much as I did when I was younger, it used to be fun, now it's just a PITA. LOL

I'm sure it's nice to have the room for all that, I'm limited to 5.2.4 here and would really love to go to 7. but just can't.

While I do get limit on surround backs, there is NO excuse for having only 2 subs :-)

Re Crossover fr. - I have Waveforming, so bass that is coming out of subs is better quality, in terms of being controlled, resonance free compared to single speaker and 80Hz on surrounds gives me more headroom for house curve EQ in 80Hz - 250Hz area.

I'd love more, how about trading off some of your excess room space just for good karma ? :p
