    Hi,

    Currently preparing my home theatre room and looking forward by planning out my speaker layout.

    I constantly hear about 7.1.4 layouts but no much or people setting up 9.1.4. The layouts from the Dolby Atmos home theater installation guidelines as attached.

    Any reason why? costs maybe or do most movies come out with 7.1.4 format?

    Room size is 7 meters by 4 meters.

    Would be great to hear peoples thoughts.

    Thanks
    Mark

    Atmos adapts to however many height channels you have. x.x.0 through x.x.max, which no human will reach any time soon. The discreet formats don't support more than 7 channels in general. So for today 7.1.4 is perfect. Will that change in the future? Maybe. Adding additional channels to a single amp is rough tho. Only Denon's top two models support 4 atmos channels out the box for instance. You can add outboard amps if that's your thing....
