Well I have the electronic skills of a dolphin.

But the idea of powered speaks intrigues me. I see
gainclones powering things like Discmans and so on.
But how much power could be delivered via a soundcard
connection direct from the computer? I don't think
I know how to phrase a proper google search for this.

However, Electronic Musician mag has reviews of powered speaks
from time to time. PCs use powered speaks of some sort
so I'm wondering if the dots can be connected.
