Reference 3a Grand Veena for a small room?

I have a relatively small listening room, about 10 wide by 12 deep with high vaulted ceilings. My setup is near field, sitting about 6 feet from the speakers, with a large overstuffed couch on the back wall.  I have always had small monitors (ls3/5a, kef, reference 3a, proac) and now have proac tablette anniversary., partly due to the room size and partly due to my love of soundstage and imaging, and no need to go loud in the small room.

I listened to a pair of reference 3a grand veenas (the older ones and not the be tweeter version) recently, loving them. Desire for ownership started to sink in.  But I began to wonder if my room is too small for them. 

and home editioning a pair likely to be impossible, partly due to my desire for the older non-be tweeter versions which would have to be purchased used.

certainly a small room limits the ability to play around with speaker positioning to find the perfect location. But this has not been an issue with the monitors, as I still have plenty of room to move them around to find the sweet spot.  Wondering if this would be an issue with the grand veena, with the rear facing bass port. Or any larger, floor standing speaker.

driving the speakers with el34 tube amps, the prima luna HP premium.

any advice is appreciated.
