Resonance issues

[KingCur]

My new set with 804S speakers is standing in a new house with hard walls and a tile floor. Occasionally, more so at higher volumes, the sound seems to reflect on the walls, causing a less harmonious sound-picture. Are there any easy-to-install ideas as to improving acoustic qualities of "hard" spaces?

Thanks in advance,

You could make up some sound deadening panels. If you are interested I will describe how to do it.
