Thanks - Have a good sleep! FYI, this is a dual purpose room so I will have to make some compromises.

I've updated the Pic in the OP to show the seating position (from what has been described to me by the designer anyway) and changed the location of the speakers slightly, but:
- I have flexibility in moving the 4 x IC speakers anywhere
- I have flexibility in moving the 4 x Surrounds except for the height but they will NOT be at ear level (about 3m off the floor) but I can angle them down
- I can put a Sub in either or both of the positions marked

The physical build will not be till late Jan / Feb but I'm keen to get the equipment ordered so the builders know what to deal with. From the Feedback so far I'm now leaning towards:
- Pair of In-Cabinet M80 but they can only be 250mm deep
- In-Cabinet M180 but it can only be 120mm deep (eg like the depth of the custom on wall you sent me last time but with the In-Cabinet face)
- 4 x M3 On Wall Angled Down for Rear and Surrounds
- 4 x In Ceiling for Atmos
- All will need to be paintable
- 1 or 2 Subs (not sure what model for this size room, 2 x EP500 or maybe just a EP800 ???)

Thanks
Nathan
