You need a combination of absorption and diffusion in a room to achieve the right balance. Diffusion helps spread sound in a room diffusing standing waves without removing energy content from a room. Rooms that are highly absorptive often sound dead or unemotional. Rooms with the right balance of diffusion and absorption often have much wider sweet spots, and a much more open sounding room. Small rooms will sound large and larger rooms sound larger.
T-Fusor Package of four ($199 plus shipping). These call also be installed tastefully with some absorption devices to maximum effect.
