Large room fix

The simplest fix is to throw down an area rug to absorb some of the reflected sound. Next is to reposition the speakers and where you sit. Portable/temporary room acoustic panels may be the best answer. The bass panels and mid/hi absorbers are not hard to make if you have time and skills and will save you lots of $$$$$$$.

I need to place the speakers very close to the back wall around 8 feet apart. They are far away from the side way though. Can you please give some specific examples of the speakers you would recommend.

Steady now, as others have advised, tweak the room. Avoid thinking of any equipment changes, especially the purchased kind.

Csmithbarc, given your placement constraints I would not recommend dipoles, bipoles, or omnis.

Speakers with good power response that I think would work well in your room include models from SP Technology (Timepiece or larger); big Harbeths; Gradient Evidence or Revolution; PiSpeakers (3Pi, 4Pi or 8Pi); Edgarhorns; Classic Audio Reproductions; Tyler Acoustics Pro Dynamics 80; vintage Altec Model 14 and Model 19; vintage JBL Model 4430; GedLee Summa; and the AudioKinesis Jazz Module. I'm sure there are others I'm not thinking of. I'm a dealer for two of the lines mentioned here, and used to be for two others.

Shahinians are an innovative poly-directional that can get away with being placed close to the wall because their rear-facing drivers are angled up, so they're a possibility. Likewise large Silverlines Audio models are a possiblity, as their departures from smooth power response are psychoacoustically rather benign.

If you can't treat the room, perhaps something like the Tact gear would work for you.
