Michael. It is simple physics, which is why I link to a calculator so often. There is no 'minimum' requirement per se.

It depends on room size (listening distance), listening volume, dynamic requirements and speaker sensitivity. Those are exactly the variables you enter into a calculator.

I have read and do like Alans articles on power.
