AV RoomService dramatically improved the performance of our DALI demo room at Rocky Mountain Audio Fest, 2007. Initially, we had problems with mid-bass frequencies (60 Hz to 90 Hz) loading off the side-walls on the first reflection. The "slapping" sound created a room resonance and an unpleasant din in the room. Upon request, Norman Varney of AV RoomService analyzed and confirmed the problem with his computerized feed-back system. He then provided two acoustically-treated panels placed at a slight angle to the first reflection on the side-walls. The result was immediate and dramatic. The "din" disappeared, and clean, precise music emerged. Mid-bass no longer reflected into the room. We now had a room with sound to be proud of. The music was tight, with controlled bass extension and excellent definition. Perfect! I heartily recommend AV RoomService to anyone seeking to optimize sonic performance in their home. Norman's analysis and resolution of sonic imbalance is surprisingly quick and effective.
