It makes some sense to provide a powered woofer for certain kinds of systems. If the midrange/tweeter assembly is quite efficient, but, the designer cannot find a suitable woofer of equivalent or higher efficiency, a conventional design would mean having to pad down the tweeter/midrange to match with the woofer and that would waste the higher efficiency of the other parts of the system. With an active crossover and powered woofer, the system owner can use a much lower powered amp for the top end.
This is a VERY important feature of speakers, like those made by Avantgarde, because very low powered amps, when used with suitably efficient and easy to drive speakers, sound great. I have not heard ANY solid state or tube amp that sounds better (for my taste), than good low-wattage pushpull or single-ended tube amps.
