Hey all, I am about to move my entire rig to a new room and I am limited to this set up below. It's a 7.1.4 set up but with the rear surrounds deleted (as there is a wall there) and the side surrounds placed in wall far away from the recommended position. Does anyone have any recommendations as to how to configure this in the XMC-2 and/or if I should tweak these positions as none of it is set in stone as yet? I would call it a 5.1.4 but the set up for that (far bottom) has no side surrounds only rear surrounds. Cheers! 7.1.4 (modified to a 5.1.4) ![]()  Recommended 5.1.4  |

Cheers! 7.1.4 (modified to a 5.1.4) ![]() View AttachmentRecommended 5.1.4 View AttachmentIn the Dolby 5.1.4, the surrounds are configured in your system as "Surround" and not "Rear". They place them a little farther back from the centerline compared to 7.1.4 just to fill in better and not leave a hole behind you. I think what you propose will work fine. Having the side surrounds a little farther away than spec will make them a little less localizable, given they are immediately adjacent to the couch. But, if you can move the side surrounds back at all - even 10 or 20 degrees back from center - it would be better. And be sure to keep them at ear-level so there's good separation from the tops. |

Thanks marcl! 10 or so degrees back is certainly achievable, although They cant be angled as they will be in wall mounted and they will be directly opposite a stairwell on both sides so the sounds may deflect backwards up the staricase. Also see below, the elephant in the room, the 45% angled walls at the front aren't walls they are actually 4m high 2.5m wide windows, with a glass sliding door on the right and a window on the left and the wall behind and above the couch and up the inside of the stairs is also a glass balustrade 10mm thick and 1200mm high. So effectively a room of glass....................  |

Now the thing to think about is ... no good comes from putting a couch against a back wall  If you move the couch 2-3ft forward everything gets better ... bass resonances will be reduced, the surround position is better, the tops are still where they need to be, and you're probably in a better spot to engage the angle of view and resolution for the TV. |

Thanks marcl, good advice, not sure the mrs will approve but Ill give it a shot! I may even have to reduce the overhead speakers from 4 to 2, which means they will need to be forward of the couch rather than behind, hopefully that still works ok. |

I may even have to reduce the overhead speakers from 4 to 2, which means they will need to be forward of the couch rather than behind, hopefully that still works ok. Yeah I was going to say, WAF not withstanding My argument is ... what's the difference between 2 extra feet behind the couch or in front? Put a little table back there to hold beers and snacks. I think it's very important to have 4 overhead, even if the back ones are heights mounted to the wall. The reason is that the way Atmos works they can't steer sound objects front to back with only two overhead ... you need at least four. If you only have two overhead the Atmos becomes much more static ... like channel-based surround. That's one reason 5.1.4 is better than 7.1.2 if you have a limitation. If you can't move the couch it will still work well though. Put the two front top speakers at 35-55 degree angle up from the couch in front. Put the rear tops as far back as you can, even at the wall-ceiling boundary on the sides if you have to. |

I am pondering your advice to go with 4 overheads. One thing I didn't mention, is that the ceiling is vaulted. So the overheads will be at an angle although, due to this angle, they will be pointing to the center of the room and effectively the listening position, so maybe this is not a bad thing as they would be pointing straight at my ears? I guess normally they would be pointing straight down on either side of the listening position. |

That's how they do it in theaters, albeit with many more top speakers and many more listeners ... so it's a bit of a compromise. But in our listening rooms we can do a better job if we point the speakers at the MLP. |
