Sure, why not?

If the material, format, and gear ... existed for HT implementation, it could be great in any room.


The current surround format engineer directs the gun shot effect to a specific channel, ie., left rear, and hopes the end user has placed his speakers properly. 

Whereas the Atmos engineer places the sound effect at a specific place in the room, and your Atmos software algorithm, and associated hardware ... places it accordingly.

But just like you need space behind the listening position for back surround speakers in 7.1 for it to make "real sense", I wanted to know if "squeezing" all those speakers into my small room will even make sense? Will it be like trying to take a Ferrari to its limits during rush hour? By the way, how many speakers do you need for Dolby Atmos in a home theater setting? 11.1? 9.1? Secondly, DTS also has its own object-based sound format coming: DTS-UHD. If I setup my home theater for Atmos, will it "automatically" support DTS-UHD provided my processor supports it? Basically, I want to know if the speaker setup/arrangement of Atmos is the same as DTS-UHD.

EDIT: Whoops! DTS-UHD is for headphones while DTS' version of object-based audio is DTS-MDA (Multi Dimensional Audio).

Gotcha, my apologies, I misunderstood.

"how many speakers do you need for Dolby Atmos in a home theater setting?"


"If I setup my home theater for Atmos, will it "automatically" support DTS-UHD provided my processor supports it? Basically, I want to know if the speaker setup/arrangement of Atmos is the same as DTS-UHD."


I don't know, I haven't followed developments at all really. 



How small is your room?

I quick/rough drawing of my room is shown in post #12 of this thread.

Yes

You're right, it's a little small. But you know, there are surround mix rooms similarly modest in size.

I'm sure it's challenging, but as we covered in the beginning of this thread, the hemisphere from the LP forward, is what's most important.

One newbie question:
How do one go about to connect an A/V receiver or a preamp with 1-2 sub pre-outs to 3-4 Submersives? Is it all about daisy chaining them or do you get a Y-connections? I don't know whether there are Y-connections for XLR pre-outs but wouldn't that ultimately risk diminishing the sound quality?

I'm wondering because from what I understand active speakers that are being connected by XLR cables should only carries the line level audio signal, and not the power. So daisy chaining several of them should not pose a problem, right? Both in terms of withholding sound quality and power, since every speaker is self-powered with its own amp it should not put any load on the receiver by halving the ohm for every daisy chaining being added to the system.

Or am I misunderstanding something here? Are there XLR outs available on SubM HP and F2 or does it require another type of connection?

Sorry for being off topic here, but I was wondering what the best practice was of making use of several active subs in a system...

Mark's subs can be daisy chained or you can use a Y splitter.  Or you can get a product like  Xilica processor to enable you to connect all of those subs as well as to set the EQ , level, and distance for each sub individually.  That is what I have for my 4 submersives.

Which Xlica processor? How do you use it??

I have the Xilica XP-2040.   It take the output from the preamp for one or two sub channels and gives me 4 sub outs from there.  The Xilica can control independent volume and other settings mentioned above for each sub.  It is controlled by a usb or network connected laptop.  You would only be controlling it while taking measurements and setting it up.  Then you just keep it on and forget about it.

Ran me around $900 I think.  I got it from Nyal at Acoustic Frontiers.

Here's a video of my theater room using the SubM HP's as stands for my Cat 12C's. Sorry for the video quality, the the combination of the cell phone video and youtube not liking safari made it come out very grainy and glitchy. I'll have to get a nice camera to take videos.

Saw this video. Tracy Chapman sounded brilliant. Very nice setup.

Thank you. The Zoom H4n made her voice sound a bit tinny, but still a huge improvement over a camcorder mic.
