Calculul puterii unui difuzor

Cum se poate calcula puterea unui difuzor, despre care stiu impedanta... :DMa gandeam la formulele P=U*I si la legea lui Ohm I=U/R, de unde ar insemna ca P=U*U/R, care ce inseamna... (?!) ca daca difuzorul primeste un semnal de U volti, avand impedanta de R ohmi... consuma P watti :) Dar puterea maxima (sau aceea la care se refera toti cand zic "difuzoru asta ii de x watti") cum se poate afla?Multumesc.
