I think all untreated rooms can be improved upon.
I was looking at a job at a church last month.
Inside, at the rear of the church up on a balcony, there was a nice choir section (and an organ).
Its dimension were about 20' high, 30' wide, 25' long.
When I looked up at the sheet rock ceiling (cathedral), my first instinct was to clap my hands lol.
Even at this size, including being open (at the front) to the rest of the church, you could still hear a terrible echo.
In fact, the echo sounded worse than the clap did.
It made me wonder how the choir could even hear themselves.
I'm guessing panel absorbers at the ceiling would do wonders to that choir section.
