Room size definition

I would like to better 'describe' (or specify) my living room when people I ask for input want to know about my 'room size'.

My living room is 25 x 15, very open on one side (25). 2 stories high (19'). 

Speaker placement is 2 ft in front of short wall (which has 2 open squares 4x5 (open to breakfeast/kitchen area on eye height), one in corner, one in 'open corner'. Listening about 15' from speakers.

18" Dayton sub in sealed encloserdriven by Elemental Design LT1300 amp (Built for eD by Keiga and based upon an ICEPower module developed by Bang & Olufsen)  is providig low bass (sufficient for my taste/need). 

I currently run the smallish front tower speakers in 'small' setting' (I found it improved the sound vs 'full range', even when I had true full range tower speakers).

I am now considering smaller 2 way speakers, like LS50. 

Concern: can a LS50 (with sub) or similar speaker with small drivers 'fill' the room (i.e. provide SPL in realistic levels)? Alternatively, I consider a (used) B&W Nautilus 804.

With respect to 'volume' of a room: how much of the volume "connected" through the 25 ft long open side should go into the equation? 

The room itself (25x15x19z) 7125 ft3. 

The volume connected through 25 long and 19 high 'open wall' is that size again (estimage), so call it 15000 ft3 air volume pressurized.

I agree with yyzSantaBarbara.  I just moved LS50's out of a room thats 23 x 12 x 8 and they were too small in that room.

Agree with the others.  You won't be happy with such small speakers in that room and the 804's would be better. But if you insist on trying, go ahead.

Another vote for the 804s.

I LOVE my 803s in a 14x15 acoustically treated room.
