Small room?? 3m x 5m isn't a small room. At least it's certainly not by UK standards.
OP - I'd add the Monitor Audio Silver 200 7G to your list of speakers to demo. It's a bit over budget new though, at £1,350
This, floor standers often have more balanced bass. A lot of stand mount speakers...
You simply cannot make a speaker choice based on published specifications alone. The specifications provided tell you nothing about how the speaker will sound. eg one speaker could be very neutral and another have a recessed treble etc. basic frequency specs as provided won't give you that...
