speakers in a bad room

I can't think of a speaker that will work well in the room as it is today. Way too many reflection points, the room must echo like crazy. Is there any chance you can do make some changes to the room? Buy an area rug for the floor, maybe hang some tapestries on the walls?

i will get a rug in front of the speakers, but is that enough ?

Dude, sound waves are sound waves. Pull out your physics book. Get a thick rug, fill a book shelf at the back of the room (with books), and buy some acoustical treatments to dampen the initial reflection points!
