If I were Dolby and DTS I'd listen up...

[Khellandros66]

Ok

after giving much thought to the current formats and the upcoming ones aswell.

5.1 = Basic Surround
6.1/7.1 Matrix =Improved Depth
6.1/7.1 Discrete = Improved Depth but more precise

IF I were to release my own format that could be applicable/practical in homes and theaters it would really be 8.1...

Where you might ask you put the 8th channel.

Front Center of course, if this channel is so important make it better by eliminating the mono setbacks.

With dual Discrete Centers the movie dialog would be more fluent and transient, and the audio placement could be more precise as far as where the actor/actress is onscreen. I watch movies and wish that dialog would be more enveloping. For instance Star Wars Ep VI when Vader is talking to Luke while looking for him under the stairs. Lukes Voices despite all the opportunites is planted in the center ranther then give depth and moving it to the front L/R etc.

You could still plant dialog in the center but with more perception as to where the actor is in relation to the camera shot.

This is what I propse to be a good placement of the channels..

The Center L/R at 25deg
Front L/R 65deg
Side Surrounds 90deg
Rear Surround Back 35deg

If you are going this far, then I'd ask them to go a little better to 10.2 that Tomlinson Holman, creator of THX, has been working and demonstrating its reality.

Thomlinson Holman has demoed 10.2 and is rumored to be outstanding. But i dont believe even that setup uses dual centers.

 

[rollinrocker]

Whoops! You're just too fast mtry!

This actually exists already. SDDS which is used in commercial movie theatres is already capable of this. (But does not get used much if at all anymore.) They use whats referred to as Left and Righ Center. So you have a total of 5 screen channels.

However most engineers I have talked to dont care for it. 5.1 and 6.1 when PROPERLY set up in a REFERENCE enviroment can be astonishingly good. But it all comes down to who mixes the movie. To be quite honest I agree. I have watched several movies in the Dolby screening room here in San Francisco and 5.1 is all you really need in my opinion.

One thing that has been talked about is a ceiling surround. This could be a possibility in the future from what I here. But nothing concrete has been started yet. Just talk from some of the Dolby folks.

Cheers

IMO, A home theater is just too small to benefit from dual centers, even if the screen is 100" wide. Two mains and a center smack in the middle encompasses the entire viewing field with sound.

If you don't care for the mix and think the center image is too narrow, that is another issue. Why not try PLII Music mode and widen the Center Width parameter? If the image seems too far forward or too recessed, you can adjust the Dimension parameter. That's what I do and I use that mode for music and movies.

Bob,

I take it the 1300 does not have the dialogue lift function. I have the RX-V2500 with this function. It does exactly what you are wanting. I have a 92" 16 x 9 screen and was always disappointed with the voices not following the actors across the screen with my Denon 5800. When you have presence speakers connected to a Yammy and use the dialogue lift function, which puts some of the center and front channel information into the peresence channels, voices are truely anchored to people as they move across the screen. I was considering an Anthem pre/pro, but am now deciding between going ahead and picking up the Z9 or waiting for its replacement because I do not want to lose the presence speakers Yamaha provides.

I've always thought 8.1 (or possibly 8.2) is all that's needed. If you place the viewer at the centre of a square, and have four speakers, one at each corner, and another four speakers, one at the mid-point of each line, plus one (or two) subwoofers, then wouldn't you have it all covered? I understand about the thing where the brain places sound directly behind you as in front, but the left and right rears of this proposed setup could take some of that sound information too, thereby negating that weird brain phenomenon. I dunno. Seems like it'd be perfect. But heck, I just started this hobby; maybe I'm spouting silliness and don't even know it.

Yes, no, maybe? But then again, there's that pesky need for dialogue to be "lifted", so I dunno.

Just the luck of the draw

No, he doesn't use two centers, if I remember correctly. I think he has two up high between the fronts.

 

[Khellandros66]

I have done extensive reading on what little articles can be found on 10.2, however I don't think this is very practicle. R/L Center would be more feasable and less consuming of space. Not to mention less cost.
