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.

You can calculate the room volume ( L x W x H) and e-mail the manufacturer for advice. That is exactly how OHM Speakers does it.

Bigger is better! Get the B&W 804's!

In my opinion, ALL decent speakers should have their -3dB point at 40Hz or less. Then use subs below that if you wish. That was common advice even in the early 1980s when subs were still uncommon. Pretty little speakers don’t qualify, as much as our spouses might prefer them for their looks.

Of course, manufacturers can make larger profits selling subs plus speakers, speakers that require fewer and smaller drivers, smaller cabinets with less bracing and lower shipping costs. I call that "Boseification".
