    Guys why is there a second .1 in the 10.2 format I've heard about ?

    My guess is that it is another LFE channel but maybe at a even lower portion of the sound spectrum.
    Otherwise I thought it might be a Super Tweeter channel ?

    Lastly where are the extra speakers in a 10.2 vs a 5.1 ?
    I have tried to look up a million site but cant find this info.

    Thanks
    Craig

    Not sure what the new channels will be for, but the channels that the designers have forgotten about are ceiling mounted speaker or speakers, for noise from above such as helicopters, heavy rain, etc.

    Imagine the noise of a plane or rocket leaving the screen from the centre speaker, travelling directly towards you, just missing your head, then disapperaring behind you through the rear centre.

    I would gladly flush mount some speakers in the ceiling above the sofa, if there was a sound format that supported them.

    The problem is I think about a year or two ahead of the technology:)

    This is getting a bit ridiculous really. I'm all for surround EX and ES ( I think Surround back should be stereo) but 12 speakers?
    For truly surround sound you need a room, a perfect cube – with the seat suspended in the middle and 8 full range speakers – 1 in each corner. Or perhaps the room should be spherical like in X-Men. That's what I'll try and get planning permission for – a spherical extension – like a nuclear reactor…

    Speaker manufactures must be laughing their socks off.

    I read once that someone had an idea for a vast NXT-style wraparound panel speaker, with a totally pinpoint addressable system. Now THAT's surround sound!!!!

    Also, re the Rear Centre speaker: don't I remember reading in HCC that anything beyond 170 degrees from front centre doesn't get registered by the brain correctly, and gets processed as coming from straight in front?

    This is true, that's why the up market amps have 2 rear channels with the same information.

    This is getting Mad I don't think we should go beond 8.4

    even that's to much but I could see the point.

    Front Left/Right Front Upper Left/Right, Sides Left/Right, Rear Left/Right and up to four small subs.

    anything more and leave it to the Cinema.

    After all there are very few Cinemas in this country that call match the most modest of our systems, and thats with me using a tiny £99 temp 5.1 system.(my main system is in storeage until next year) So give them somthing !

    Yeah as per previous comments they suggest using two speakers to get round this. Personally I reckon it's BS.

    Try this. Go outside and stand in the road with your back to the oncoming traffic. Now tell me if you can hear anything behind you !?! :D

    Bl**dy scientists... :rolleyes:

    Although I'm an advocate of 6.1 EX and ES soundtracks , I might be wrong, but the format of the future is 5.1. This is because it has enough channels to allow surround sound, but few enough to be "portable". 6.1(7.1) is only an off-shoot of this "default" format, much like 24/96 dts is an off-shoot (which is why there is no dts ES discreet 6.1 24/96 decoder).

    In a cinema you can have banks of speakers connected to racks of equipment, with the audio on CD-ROM synchronised with the film soundtrack - your limits are endless. With home audio you have an amplifier or processor/power amps(s).

    I believe that they should be getting the 5.1 (6.1/7.1) formats right first – head towards loss-less 6.1 full bandwidth high definition audio (DSD or MLP) when room allows on the disc (DVD-Blue), then build on this. Send directional sub information to all channels, then allow the user to decide how to present this information (full bandwidth speakers like B&W 800 series) or use traditional sub-sat speakers.

    That's the way forward in my opinion.

    You'd need a sub in the ceiling too since thunder is 90% bass.

    I already have that, http://www.clarksynthesis.com/ , mounted inside the Sofa, powered by an Audiolab power amp, with a Paradigm X-30 crossover set to 50 Hz - You can certainly feel the Bass :)
