I am in the final planning stages of building a new house. Pro's and con's for a vaulted ceiling in the media room. Or, a trayed ceiling? The vault would be 9' on the short wall to 13' in the center, symmetrical. The room is 16.5' wide by 24' long. I have 2 very large diy subs, Dynaudio mains and center. Will be an Atmos 5.2.2 with wiring for 7.2.4 for future. Thanks for the input.
