Dolby has never stated that, instead saying on its blog "as many as 24 speakers on the floor and 10 overhead speakers", for a total of 34 (not 32) speakers. Subwoofers are a result of bass management, not Atmos.

Don't throw cold water on the outrage machine. Posters are wanting to get upset over the premium prices that they fabricated in their imagination and here you are talking sense.

Two of the "channels" are for sub outputs just like with commercial Atmos, which isn't 64 outputs but 62 plus subs (62.2). I would imagine they meant something like 32.2.

Listen up, studios! Just say "NO" to DNR and EE!!

Just ordered 2 sets for future atmos set up. Thanks batpig for heads up. I have axiom m80s so this will be perfect.

This isn't commercial Atmos and the FAQ never mentions number of "channels" nor "subwoofers", just "speakers".

The white paper I have states 61.3 for theatrical Atmos, not 62.2. There's a LFE sub in front and one in each rear corner to compensate for the bass-lacking surrounds that are typically used in cinema's.

Same here. New sound formats don't usually carry a price increase. Even the commercial theaters aren’t charging extra specifically for Atmos (just for the bigger screen, better seating, reserved seating and so on).

True. Now I just need to replace all of my HD DVD's with Blu Ray's, and get rid of my Toshiba HD DVD player, so I'll have room for more amps !

Yes, this is inevitable, just as it was when we moved from 2 channel to 5.1 and then to 7.1 and, in some cases, 9.1 and beyond. The extra speakers needn't cost the earth though - the on-ceiling Tannoys I am using are reasonably priced, as are the in-ceiling ones that batpig found. Some will need to buy additional amps although many will find enough amps in their new Atmos AVR. And some with external amps can repurpose two or four of the AVR's internal amps to drive the top speakers. As everyone who wants Atmos will have to buy a new AVR, then this can be factored in.

So yes, we will surely have to go to some additional expense, but not as much as might have been thought. But then, when has this hobby ever being about not spending money!

Then maybe it's 31.3 to total 34. I wouldn't think Dolby would make it so onerous to scale a theatrical Atmos mix to a consumer mix or the studio post houses wouldn't easily go for it.

Yes. And I feel for some that will go out and buy in-ceiling speakers to find they won't fit. The in-ceiling speakers I've been looking at need 5" (like the KEF Ci200RR-THX) to 9" (like the Polk 900-LS and almost that much for the 700-LS) of depth, wait until some of these people cut holes in their ceiling to find they don't have enough room and have to try to make some type of bracket or return and find a pair of in-ceiling speakers that will work...

Maybe, but 36 speakers would be geometrical nonsense since 360°/30° = 12 ear level speakers is al it takes to fulfill the Dolby guidelines (for commercial theaters). Add the consecutive 6 Top speakers and you are there, unless the audience is bigger than a standard family. I'd say 24 speakers would be ample for and audience of 20 people or so.

My best guess:

1. Business as usual; on the back of the Blu-ray cover it will keep saying Audio* Dolby TrueHD: English 5.1 (or 7.1)

2. And @ the very bottom we'll see a new DD Atmos logo.



* It might also have that aDDitional small indication (like above), somewhere on the front cover.

Ah so... sorry, I thought you had. Nonetheless, they do look pretty useful. The sealed in-ceiling designs appeal to me much more than the open-backed type.

Counting subs as speakers, I already have 27 in the room. 9 more doesn't sound that impossible.

Subs don't count it is a given that you will have at least 4 subs

Two 24" in a room of 4 by 3 by 2.5 meters would do just fine.
