It’s all about optimizing room acoustics, and the best way to accomplish this is by placing your speakers around the room. Setting up each one to face your listening position will allow you to control the way sound is absorbed and reflected. Another huge tip is moving your subwoofer away from corners, as it can limit bass notes and even cancel sound depending on the room dimensions. Most new AVRs launching this year will feature DTS:X, which allows you to place speakers where you want them, instead of having to place them in a specific spot.
