Dave,

What in a speaker design dictates that number?

Sorry I missed this... There are far too many variables involved in determining a set distance from a wall -- it really comes down to one's personal taste. A general rule of thumb is twice the port diameter, but I have never quite understood the logic behind that recommendation as port diameter is only one parameter in determining airflow velocity and tuning of the resonator.
