High ceiling or low ceiling, as long as you keep those overhead speakers at least 30 degrees away from the centre line, you should be fine.

Is that why 6.1 never took off?

That was one of the reasons why 6.1-speaker set-ups didn't take off.

6.1-channel content wasn't a problem, whether discrete or matrix. Dolby, DTS and THX all recommended using 2 rear speakers to play back the mono surround-back channel of their EX/ES encoded soundtracks. Note that it was the only channel where 2 speakers (dual mono playback) were recommended.

Of course, once you have 2 speakers back there, why continue to mix soundtracks with a mono surround-back channel. So it was a matter of time before we got stereo content (7.1) for the 2 rear speakers.

The Auro decoder doesn't care. Just feed the group from one signal.

I know its different, but I had no choice in our living room (3.3m or 11ft high ceilings) for the "side surrounds" and it works remarkably well (they're good speakers - Rogers Compact Monitors, but the envelopment is really quite surprising) This is coupled with the rears that are about 5m away and high.

Going to (finally) pop my Atmos cherry today with Elysium at Look Cinemas in Dallas! Already read a review here about Atmos at that specific theater which was good, so I am looking forward to good things. I'll post my thoughts when I get a chance after.

Do you think we will see any AV prepro or receivers with ATMOS at CEDIA! I don't think so but wonder who think otherwise?

Seriously?

Not a chance. I'd be surprised if there is a home technology ready for market from Dolby before late 2015.

IMO first we need virtualization improvements.

The cinema market is in flux right now.

Until that settles down I doubt we will see content provides willing to make the investment in > 7.1 content.

Be careful what you ask for - more speakers, more amps, more wiring, more processing, marginal improvement.

Um, no.

Atmos is not a "marginal improvement" over 7.1
post #581 of 922
Cost/benefit wise Um, yes.

Folks used to say the same thing about Dolby Surround vs. 5.1

As mixers become familiar with Atmos the differences become more apparent.
post #583 of 922
Nope 2.1 to 5.1 was a leap. 5.1 to 7.1 not so much. Atmos considering the costs - not so much. Or even not considering the cost IMO for the HT.

Have you been to many Atmos engagements?

The difference between the 7.1 and Atmos versions of STAR TREK INTO DARKNESS was a leap.

And recall the dark days of 2.0 vs 5.1, where people complained the 2.0 versions of certain films were more "immersive" than their 5.1 counterparts. Forrest Gump immediately springs to mind.

Investing in a new LD player, new receiver or outboard decoder, full range surrounds, etc. Active vs. passive subs. It was a substantial investment for early adopters.
post #585 of 922
As I was careful to say I am talking about HT - where I believe it will be niche regardless of a Gump-type outlier you may be able to point to here and there.

An August 15, 2013 article on FilmJournal com "Self-empowerment: Fully contained speaker systems meet the demands of immersive surround formats" (link) discusses some benefits of using self-powered speakers in the Dolby Atmos theatrical environment.

Although it seems likely a minimum configuration for the (still only speculative) Dolby Atmos home theater will contain between 7 and 13 front+overhead+surround speakers, it is possible some systems may contain more speakers, and others may add another pair or two "after some time". Perhaps expanded use of self-powered speakers in the home theater environment might provide a more flexible alternative to buying (e.g.) a six channel 'surround amp' now, to add only 2 new speakers--with just the anticipation that you might possibly add up to 4 more 'at some indeterminate future date'! cool.gif

I missed this thread until now. We have a full Auro 13.1 config in our UK demo rooms (actually 15.4 system) thanks to Barco. We were first to have this full system in a resi setup so I am pretty familiar with it from a design and playback perspective now.

I can say that the full immersion of the 3 layer system is quite extraordinary as it seems to totally redefine the apparent room boundaries.

True auro material decoded sounds best of course but careful configuration of the 13.1 upmixer also works amazingly well for blu ray although 7.1 mixes are noticeably better than 5.1. Obvious when you consider it but interesting as a point for experimentation.

There is some tricky commercial background to Auro codec and I do not expect to see anymore than 9.1 on consumer products anytime soon. That of course leaves an interesting option at the very high end for consumer/commercial cross over systems at home.

Oh my too bad I am in San Diego, I would love to hear that room are you using self powered speakers?

I would use these http://www.jblpro.com/catalog/general/Product.aspx?PId=469&MId=5. With four subs

Obviously, the mixed-for-home channel count included within the Auro-encoded 5.1 or 7.1 LPCM carrier track on a Blu-ray disk is decided by the studio . . . and the maximum decode+upmix channel count (9.1|10.1|?) is the result of a feature decision by the AVR|processor vendor. Similar "complexity reduction" questions will doubtless apply to home Dolby Atmos (max number of simultaneous objects supported, max number of render-to speakers allowed, etc.) At least in part, this reflects the conflict between ensuring the theatrical movie experience remains unmatched by home viewing . . . and the 'promise' that you can enjoy "something close to the movie theater experience" again at home by purchasing the BD (plus some expensive AV equipment! biggrin.gif)

And it will be interesting to see how 3D audio decisions for ATSC 2 and|or ATSC 3 affect this thinking over time . . . especially as post season disc releases of TV shows are designed to entice audiences to watch future broadcast seasons. cool.gif

An August 15, 2013 article on FilmJournal com "Auro & Atmos: A status report" (link) asserts there are 500+ Atmos or Auro3D theater installations in-place or with signed commitments at this date. So it sounds to me that theatrical movie 3D audio (in one form or another) no longer need be described only as an interesting experiment...?! cool.gif

Sorry for the OT post, since it is not Atmos related per se, but since this is the only Dolby thread going at the moment...

Ray Dolby, founding father of Dolby Labs, just passed away today at age of 80.

Sad news today...the man who founded the company that invented this system is in audio heaven. Ray Dolby died at the age of 80 according to news sources. May he rest in peace.
post #598 of 922
Very sad to hear. Always sad to hear when an important person to the industry is forever gone.

I would't hold my breath for Atmos at home anytime soon. When I seen Brave in Atmos on the opening weekend roll-out of Atmos at a KC AMC they had a Dolby rep there to annouce the movie and talk about Atmos before the show than personally answered questions after the movie was over. Me and a group of guys talked to him for about 20-30 minutes and he made it very clear not to expect anything for the HT market anytime soon. He said for next 3-5 years they will be concentrating on getting studios involed in Atmos as well as cinemas. I just wouldnt hold your breath but it is fun to speculate.

Too bad you don't have any demo rooms in North America frown.gif Saw that you guys had a contact in Huntington Beach but than realized you said UK rooms ...shucks

According to wikipedia, Ray Dolby's cash flow declined somewhat as a result of shares of Dolby after they went public in the mid 2000's. The shares will rebound as the company will pursue the future of Atmos and other formats. Nearly every recent movie mixed in atmos has the Dolby Atmos logo in credits after the movie instead of Dolby 7.1 or Dolby digital. I saw it in star trek 3d. Maybe in 10 or so years there will be as many atmos theatres as much as every other format dolby theaters. The most common dolby format is dolby stereo.
