I second the ATS recommendation.
Their panels are well made, effective, and priced fairly.
Do get some without the wood panel on the back. They can then work to some degree as bass traps if mounted some inches from the nearest wall.
Absorption works best toward the speaker end of the room.
In the rear use some diffusion.
