Hi gav, even if it requires moving your telly to the right, I would highly recommend to use the 2 metres distance Kudos suggests. Make sure to have completely the same distance to the sidewalls from each speaker. This will also negate the right hand side door way for space I suspect. Even your current set up will suffer time-domain issues. It WILL make a big positive difference promise! Good luck Peter
Don’t be disheatened if you can’t get them to gell. Despite the high regard, that was my experience when home demoing unfortunately. Nice with some music but lacked bass in my room and in no way were they willing to rock. Your mileage may vary of course. Nice room BTW.
Mine are exactly the same as @james_n Six feet apart, and (after much experimentation), 8 inches from the walls. In my experience, they are not as sensitive to positioning as previous speakers I have owned.
If you aligned the inner edges of the speakers with the outside of the screen, the tweeter to tweeter distance will be about 2.25m, only 25cm more than 2m. There is no reason why that would be a problem; it would be potty to consider moving large speakers every time you want to watch a film. 25cm can’t be that significant and will be affected by how far away you sit anyway.
I appreciate your set up is sort of a surround type, but it’s all about 1st reflections. This is where an equal speaker/sidewalls distance is so important. HH is also alluring to this, and it does indeed make a heck of a difference. With a symmetrical set up, and getting your left channel out of the corner you’ll experience much better cohesion of your sound and bass balance. This is my humble set up to give you an idea ( 190 centrimetres between drive units in my case)
Listening room is 4.5 mtr x 4.3 mtr, speakers firing across the room.
23cm from back wall, 2 mtrs apart, LH spkr 120cm from side wall, RH spkr 65 cm from side wall
Rack is between the speakers…use to be speakers firing down the room, rack where it is now…prefer current set-up. Speakers approx 35 cm from rack. No toe in, I think they are designed to be listened to ‘off axis’…
Sounds pretty good to my lugs…
My advice is to try out different placements as you are able to, they are quite forgiving speakers in my experience…if they work out - great, if not then you know to try out others.
Good luck and let us all know how you get on
edit - I think the 250DR will drive them well, I have had a NC250.3 on demo for 7 days and it was fine.
