Bigger is NOT always better IME... The larger room may well be better, but there are a number of variables that come into play. One of the variables has already been mentioned, and that is the ceiling height. If the ceiling height is the same in both rooms, then that would play to the larger room. Another variable is what are the walls like, are they at angles? Do they have a lot of glass/ windows vs. less glass/window in the small room. How quiet is the surrounding space? Lots of variables.
If all else is equal, then I would say definitely go for the larger room, but things are not usually equal. Let your ears decide.
In my room, which is about the same size as your current one, ( actually a little smaller..10X11) I enjoy a vault ceiling to 13’. The vault is the saving grace. The room sounds far better than my prior room which was 15’ X 25’ and with an 8’ ceiling...off the kitchen.
