Best Speaker Choice for my very "non-audio-friendly" Living Room

New to A-Gon, and looking for advise on purchasing a set of speakers.
My room is about as sound stage unfriendly as you can imagine (Hard to describe) as the center of the room is a huge fireplace with speaker placement options limited to about 25' apart from each other on each side of the fireplace. The room is approx 30' by 14' so my listening distance from each speaker is 15' & 16' from my center chair.
With that said, I have always (maybe wrongly) been inclined to buy big powerful speakers in an attempt to fill the room with good sound.
Up til now I have been running an Anthem 540 Amp, and running my fronts through a Peachtree 500 from the Pre-Outs on the Anthem to a set of Cerwin Vega Twin 15's. I actually liked the sound of this setup, but the twin 15s were just huge and honestly obnoxious on the living room (my wife had a stronger opinion on that than I did lol) 
So, I have moved the big Vega's down to the shop / pool room  and thats where they will live with a modest emotiva amp/pre amp combo that works well. 
I like the option of a Klipsch Cornwall (old school look, but much shorter and more esthetically appealing than the Vega's or maybe a set of Focal 948's which I listened to at the local shop. Both of these options are in my price range, and I "think" would give me the sound / performance I loved with my Old Vega's but look much better in the room. 
Any advice from the experts on this forum would be greatly appreciated. 
Look at the higher quality in wall and in ceiling speakers. With your requirements I would forego worrying about imaging and just concentrate on clean, clear, dynamic sound that let's you enjoy your music in more of a club like atmosphere where you hear the music regardless of where you are physically. 

You could also have a set of monitors on stands that you set up occasionally when you want to listen in a 2 channel stereo setting. I have a friend with a very large/expensive home that presents like a beautiful model, but no unsitely wires anywhere to be seen. All lighting is from above or built in wall sconces. He brings in his speakers (Tidal "Piano"), which are in a hidden wall cavity and hooks them up to a killer hidden system. He may leave them there all weekend or if he plans to listen during the week. 
Audio Solutions makes some really nice speakers which are not too picky on placement 
It seems you want to fill the room with music/sound if imaging is not hugely important.

I would also recommend the Spatial open baffle speakers if space allows for them.
Ohm are really friendly in a room just like yours.. No crazy prices and they are not hard to set up.. If things change they are still a good omni direction pleasant sounding speaker.

Open baffle? I got no idea on that one.. they do have great sound effects.. They are super hard to get right in a treated room much less a weird room.. I have a few OB designs.. What a PITA.. Dipoles that's a different story.. two different baffles 18-24 inches apart will work... BUT a common pole.. no way to get the timing right.. 

Maybe GRs OB servo subs.. They work pretty good..
