What are the best Room Accustic Treaments members have found?


I  am looking into adding some room acoustic treatments to my room.  I am just looking for advice on some simple room treatments that fellow members found worthy of purchase.

GIK is the best! The free consultation is very helpful. 

Don't believe anyone who says that something thinner than a GIK panel can treat your room. It can't. It's physics.
