From what I read I guess you can't place the monitors that optimal in the room. If you also will not need very high spl, in my opinion in such a scenario you don't need to spend that much money for the monitors. You won't hear the small differences that much if you equalize the speaker to the same goal. It is more important to decide if you rather like a narrow beaming speaker or a wider beaming speaker. The Neumanns are more narrow and the Focals or Genelecs are wider. And the psi is kind of between. Have a look at the di index of a loudspeaker and you know (to some degree) how wide the speaker beams and in which frequencies. The frequencies from 300Hz to about 4kHz are the most important part to have a look at.
Very important is a good integration like a automated equalizer measurement system or doing some research and doing it by yourself.
Deep bass is also very important and you can only achieve it with a subwoofer given the small space and limited budget. But a very good integration of the subwoofer is needed especially in the near field, which involves a placement of one or more subwoofers which is inconvenient and not very easy to do.
Self noise of the monitors also can be an issue, which you have to consider.
I would recommend to listen to some wider and some narrow monitors and get a feeling for the differences and determine what you like better.
When you compare sound you have to be aware of the psychoacoustics of hearing differences, which es very well described here.
