With new construction on a 13'x20'x9' dedicated ht, what have other members experienced in regards to acoustical treatments? Do I wait until I hear problems or plan and purchase now. Money is an object. What have people found is most important bass traps, FO reflections, etc? In the gallery it appears that most rooms don't have the amount of treatment (if any) manufacturers recommend. Are there things I should do now and wait for others? I worry about a "dry" space. Any opinions would be greatly appreciated.
