Given an amp with a low enough output impedance, like one of the solid-state monsters, you'll find essentially the same power output no matter what the impedance, frequency or phase angle. This is, of course, not the case with most all tube based amplifiers. With a higher impedance output amplifier, the equation becomes quite complex. The only audible artifact of differing amounts of power, at different frequencies and impedance, is a deviation from "flat" response. Remember, low output impedance is not a panacea, For example, a woofer's critical dampening impedance is where you'll have the best bass control the maximum power transfer. This is seldom anywhere near the typical solid-state amp's almost zero output impedance.
