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.

That is a room you stick some Sonos speaker in for background music. It can never be a serious music listening room. You need another room to set up a serious system.
Thanks again everyone! I moved my "temp speakers" Old set of nice Infinity RSB's to the Mantel bench on each side and the improvement was 100%. I cant thank you enough for steering me in that direction. My wife was even impressed, and she could care less lol. 
So with the room being what it is, speaker placement was the first hurtle i have now overcome. 
So a nice "bookshelf" size speaker will be my next choice to upgrade to and I will likely add a nice set up cables, and call it good as the room certainly does not justify much more than the 10-12K I will have invested. (I know that's a laughable amount for a lot of audiophiles) 
I'm looking at the Elysian 2's and a couple other options, something in the under 36" tall range as the full size tower options on the mantle will put the tweeters too high..for sitting listening position. 
Thank You all!! 
As has been mentioned, typical box speakers are not great off axis.  In addition to open baffle and omnidirectionals, wide dispersion box speakers can be good off axis e.g. my LSA bookshelf were under $2k and are great at this and not sensitive to room placement.  You can try them at home and return them if they don't work (Check with Walter at LSA who is very helpful)
