Your system will not sound like it should without a thorough audio calibration by a person skilled in the task using quality tools. This applies to expensive as well as less expensive systems. Many people who are dissatisfied with their surround sound continue to change equipment when the real solution can frequently be found within the equipment they own if only they had it setup correctly. Next Level Acoustics fully endorses the following audio calibrators for our entire speaker line.
