Can monitors sit on a TV console instead of stands?

Most setups sound best as an equilateral triangle, or close to it. Eight feet apart and sitting 9-10 feet back should be no problem. Also, experiment with toe-in. Makes a difference.

@tomcarr, thanks,!will monitor speakers be enough for a 14'x14' room?

That would depend on the size of the monitors and whether they are supplemented with subwoofers.

My room is 12" x 18" x 9" and my ATC SCM19's + subs is more than adequate. 

And having them 8' apart and 9' from you is almost ideal and allows you room to tweak their positioning. Something having them on the cabinet doesn't allow for.

3 meters away from monitor speakers is extremely too far. If you can place yourself away THAT far from speakers, perhaps you should consider getting a couple of horn loaded giants or at least, as you've mentioned getting a legit "cruiserweight" ...to... "heavyweight" types of floorstanding speakers. 

Even at the stage of live performances is at the café venues like Birdland, Irridium or BBKing, I would probably find myself closer than 3 meters away most-likely

@tonyl719 A foot x foot-and-half x 3/4 foot is very small room anyways. How you can stretch to 3 meters no idea.

They will sound better on stands — more space to breathe and more flexibility in placement.
