If you have time, money, and an obsessive-compulsive disorder, you can build your own ideal listening room.
First, the room dimension ratio is more important than room size. The perfect room ratio is 1:1.4:1.9. An example would be ceiling 10 feet, width 14 feet, and length 19 feet. This ratio avoids room resonance from low frequencies. To further reduce room resonance, resilient channels should be used to isolate sheetrock from studs on the ceiling and the walls. Don't forget to use R-15 insulation, and solid wood doors to keep the sound contained in the listening room. The right amount of carpeting and drapes will absorb excess high frequencies.
