Do you have any space or wife restriction? What's the size of the room?

I would only go for a projector, if it is a dedicated movie room and you have another room, another possibility for having an everyday tv).

For an ’all-in-one’ experience with tv viewing etc and movies, I’d go for a bigger tv....as Miki suggests a BV11-55 (or an Avant55).

If possible even bigger (an Eclipse 65).

Same thoughts about the sub - when sub then the BL19.

In a movie only room you could go for a BL2 or even better two of them - but they can be hard to tame....depending on your room.

As Miki wrote - with BL5/20 you won’t need the sub.

Got it, thanks Jaffrey!

Sorry hit enter too quickly.

Thanks a lot Miki and Millemissen for your advice!

It's basically a warehouse conversion with an open living space of about 8m x 6m, the front 4m x 6m is where the tv and speakers will go, with the rear 4m x 6m housing the kitchen and dining area. If that changes anything?

yes that changes it massively, there is too much volume too fill/too much volume for the amount of sound energy created by smaller speakers to keep the pressure levels up. They could still sound good, don't get me wrong, but they will have a very hard time sounding imposing or big. So for a space that big go with lab 5's all day long and 17's rear, they'll have a much easier time of making it sound good and you don't have to crank them so much, aka you'll have some headroom. 

on which axis will everything go? will the 6 meter wide bit have the screen(so front to back speakers will be 4 meters?) or will the 4 meter wide bit hold the screen (so front to back speakers is 6 meters)? My livingroom is about 6.5 meters front to rear speakers and I recently went from 5.x to 7.x and it made a huge difference in sound as my couch is more or less in the middle of that space. So my thinking was that nowadays 4x lab 3's are roughly equal in price to 2x 17's so that would also be an option and maybe even the superior option (of course you could also go 4x lab 17's lol) to go with especially for mostly movies.

Just some thoughts, could you maybe send/show a picture of the space so we can see and be more helpful?

btw, how high is the ceiling?

In my old house I used to run the "Classic" Beoliving setup with a Besosystem3 with BV4 50, a motorized screen with a JVC HD1 and BL5, BL7-4 and BL3. Viewing distance to the screen was probably 3,5m. The 50 inch screen is a little bit small to my taste especially with HD content. 

The biggest issue was the performance of the center to keep up with the BL5. I tried a couple of different setups, 7-1, BL3, BL4000. The BL 7-4 in my setup had the least "hole" in the sound experience. 

An other drawback these days is the missing room correction which is in most receivers today. If your room is not perfect (and this might be true for most of us) the can make a big difference.

For a dedicated home cinema I see to many issues with B&O today, but for casual viewing and not a die hard sound geek this is OK.

Thanks Miki.

The 6m wide bit will have the screen and front to back speakers will be about 4m. I'm actually hoping to use it more for music than movies to be honest, but still nice to have some surround sound for movies when it happens. I'm no audiophile though but appreciate a good sound!

Definitely, pictures of the space attached. Apologies, I'm not the best at taking photos.

Ceiling is on a slant with the lowest point about 2.7m high (TV side) to the highest point about 4.7m high (dining side).

Thanks so much again!
