In studio acoustics the room measurements are used to define the specific problem frequencies (room modes) of the room. Then it’s common to try to control those frequencies. It’s simple: the smaller the room the more problems. The bigger the room the better.
My philosophy was: “why solve problems if you can avoid them?”
Thats why the studio was build so huge that there are no room modes over 30 Hz.
