Where are you going to place them in the bedroom exactly?
I always had a hifi system in my bedroom since I was young. The most obvious placement was on some furniture on the opposite side of the bed. A couple of years ago I moved to another house, the front wall was totally taken by a large wardrobe. No space left for speakers. So I placed the speakers right at the bed corners, basically in the middle of the room
Different position, different speakers characteristics.
I must say I definitely prefer this setup - with the proper speakers of course. I run mains and ethernet cables under the bed, TV and electronics are placed on a small desk in between the speakers. It's a very clean setup.
This setup would be great for monitors like the already mentioned LS3/5a - as long as you can live without a deep bass extension. I think also a set of active speakers (Kef?) may be a good choice, this will also help in making the setup nice and tidy with no need of other boxes around.
