Power handling is determined by the limits of the components used. Coils and resistors are rated in maximum current and capacitors in maximum voltage. So you can get whatever size you need.
Check the π crossover document for more information. Pages 67-80 are specifically about power handling, and illustrate the requirements of each component with voltage curves.
