DTS Theater Sound Goes to 11

DTS rocked CES with an 11-channel home cinema demonstration to introduce its Neo:X technology.

DTS filled its CES theater with sound thanks to an 11.1-channel surround array in a circular configuration, as well as ceiling-mounted height speakers, that demonstrated its new Neo:X processing.

It’s fitting that DTS authored the high-res lossless soundtrack for This Is Spinal Tap when the cult classic arrived on Blu-ray, because the audio company has cranked its latest format up to 11.

There were plenty of rockin’ home theater demo at this year’s Consumer Electronics Show (CES), but none quite as unique as the one in DTS’ booth.

Forget 7.1- or even 9.1-channel surround sound - the DTS theater packed an 11.1-channel punch. Following in the footsteps of rival Dolby Laboratories’ ProLogic IIz technology that debuted in 2009, which adds “height” speakers above the front channels, DTS unveiled its “Neo:X” format in Las Vegas.

Really, More Speakers?
Surround sound in the standard 5.1-channel setup - front left, right and center channels, two side or rear channels, plus a subwoofer - really took off with the advent of DVD and later with receiver/speaker “home theater in a box” packages. As CE pros who have installed thousands of such systems over the years, home theater goers find traditional surround sound mighty enveloping - after all, some say audio is half of the home theater experience.

So why add more speakers, and therefore a more complicated installation, especially for homeowners who want to wire their own systems?

Part of it stems from the fact that thanks to Blu-ray, people have already started adding speakers to create 7.1-channel surround systems that take advantage of DTS-HD Master Audio and Dolby TrueHD lossless formats that have been mixed with additional audio information. And part of it is the emergence of 3D technology into home theaters and the desire to produce even more immersion.

“We see it as a complement to 3D technology, and people can configure it in a couple of different ways to really have an engaging experience,” says Geir Skaaden, VP, North American licensing operations for DTS. “Neo:X was designed with the goal of generating an additional dimension ‘height’ to traditional 7.1 surround sound playback, while maintaining a natural three-dimensional sound field consistent with the artist intent of the original mix.”

Of course, it’s difficult enough finding Blu-ray discs that include native 7.1-channel soundtracks, so don’t expect 9.1- or 11.1-channel audio tracks on those high-def discs anytime soon. That’s where the processing comes in, as Neo:X takes 2.0/5.1/6.1/7.1 formats and converts them within a single algorithm to 9.1/11.1 to deliver discrete effects to those additional channels.

For an 11.1 configuration, height speakers would help convey effects of planes, thunder, rain, background music, etc., while width speakers would expand the front sound stage and enhance front-to-side actions, like cars moving across the screen or bullets zinging by, says DTS.

“Neo:X has been designed with great flexibility so people that have an existing 7.1 system can either add four new speakers or reconfigure their existing speakers to generate height playback,” says Skaaden. “For those planning their home theater, this is another option if they’re looking for the ultimate home audio experience.”

Or you could just properly set up a 5.1 system and achieve all the “effects” of height, width, sound from beside, above, etc.

Seriously 11 speakers and a sub…just what my wife wants…oh and 3D glasses…how much equipment do I need to “experience” 3D.

I’m good with just my 5.1 setup properly and my 60htz 2D Sharp TV.

And we also need razors with 11 blades.

For the “best” sound experience, it would probably be smarter to use the money spent on 11 speakers to buy 5 better quality speakers or a second subwoofer and, as Kivritsky points out, set it up properly. The height, width, etc. may not be quite as specifically detectable, but the overall sound experience would be much superior for the same investment.

I’m going to run out and buy all that, because an 11-speaker setup really is practical, and, let’s face it, necessary to enjoy home theater… Wait… What?!... No, forget it. 11.1 is absurd.

5.1 set up correctly will be fine.

Only one sugestion for all the 5.1 die-hards. IOSONO Sound. if you don’t know what I’m talking about the closest experience is in Orlando’s Haunted Mansion.
Make no mistake, more speakers with a well done mix translate to a more realistic and natural sound.

If you want to see the “enth” degree of what is available, far past any 9.1 or theme park, just look at the Kipnis Studio Standard. I can’t put the web address due to posting guidlines, but Google it and read it well!

Here’s a story we did on Kipnis’ HTs a couple of years ago: http://www.cepro.com/article/inside_the_88_kipnis_studio_standard_home_theater_system/

These systems are nothing new however. I can remember seeing Tom Holman about 10 years ago demonstrating I believe what was a 14.1 system with multiple subs using gear from Bryston and PMC.

@Robert,
Actually Mr. THX was one of the principals behind Audyssey DSX, than Dolby and DTS had to catch up. The system he showed was a FANTASTIC 11.2

The guys that are holding on to 5.1 now are the same people twenty years ego holding on to 2.0

Posted by Robert Archer  on  03/11  at  06:26 AM

Thanks Enrique, I’m aware of Holman’s involvement with Audyssey. I’m not sure however about him pioneering surround sound before Dolby.  Dolby had been doing surround sound before Holman even made a name through Lucas Films.

1976’s The Song Remains the Same from Led Zeppelin was one of the first Dolby Surround soundtracks to hit theaters.

As for your comment about 5.1, most people prefer it because there are only so many speakers that people want in their home spaces. Add to that the cost of adding more speakers and it’s easy to understand why 5.1 is what it is.

Throw on top of that the cost to the production process of adding additional mixing channels and subsequently the lack of native content beyond 5.1 and it’s obvious the market is satisfied with 5.1 lossless surround.

People should be happy that Dolby TrueHD and DTS Master Audio are available. These formats are as close to the masters that consumers are going to get.

I have 7.2 and love it. With the correct surround speakers (Axiom QS8’s) and two subs you cannot go wrong. I just wish they would start to produce sound tracks to take advantage of the speakers we already have!

5.1 is great depending on the size of the room.

7.2 is not any “better” just needed for larger rooms.

I do think that two subs is always better even in smaller rooms as it smooths things out a bit on the low end.

But come on people, 11.1, or 13.4, or 73.12??? This is just a ploy to get people to upgrade again and spend mucho $$$ on something that is clearly overkill for the average person.

Robert,
What I ment was the evolution behond 5.1 was mainly push by Tom. Audyssey was the first one to come out with a scheme for Wide and Height channels and by no means I tried to implied that he invented surround sound. I’ll give that credit to Jim Fosgate.
My point is, if we are in the Custom Installation bussiness, we should not limit our minds for average or basic set-ups. we should be able to demostrate past the standard of what everyone can get at BB or any other of the big chain stores. It is only a matter of a short time before they start mixing for more channels

I always present to my clients what they cannot get anywhere else, and let them make an informed decision of everything that is available at the time.

Posted by Robert Archer  on  03/11  at  08:28 AM

Hi Enrique, I agree with most of what you are saying, but where I differ is that installers should focus on making the 5.1 experience as good as it can be.

It’s my opinion that it starts with system design that focuses on room acoustics, and audio and video calibration.

Yes, Dolby’s new height and surround channels add depth, but the problem with these technologies is that there’s hardly any content beyond a few gaming titles that utilize those channels as discrete solutions.

Studios have a hard enough time justifying the provisions to mix in 5.1, they certainly don’t have the money and space to add more channels during the engineering process.

Because of those reasons it’s unlikely there be a lot of content mixed to take advantage of those additional channels.

Posted by Enrique  on  03/11  at  09:03 AM

Robert,
I agree, just that 5.1 is the basic set-up and is something that’s been done for about twenety years now. I believe is time to move foward on the audio side to keep up with the advancements of video.
Also, in a typical living or family room is harder to go with more channels, but for someone with a dedicate room, the sky is the limit.
We need to realize that we get more features than what we really need nowdays, but that’s not going to stop us from getting and utilizing them and being able to offer them to our clients.

Anyways, good talking to you, I enjoy your reviews and comments. Good Weekend
