I know one of our members makes is copper pots in 3 inch pots and I think that is the only way he makes them. He is well known for his copper pots. Mike Yingling, his name just came to me.
Speaking with John Sinclair a few years ago he said there are certain combinations of wood, soundboard and striking surface he will only do in 3 inch pot as they don't sound right in a three and a half inch pots. I Know I have one other that is a three inch pot that also sounds good, but I am just waking up and my already defective brain does not start working kinda right for a few more hours.
